Green River Observations for 2020 October 17

This morning we checked out Woodside Geyser. This feature is located on private property, part of the old town of Woodside and now completely off limits. Based on memory and satellite maps, we figured our best opportunity to see anything of the feature would be from the Union Pacific railroad embankment to the west, just north of the bridge across the Price River. Photos online of the geyser from a few years ago show it erupting quite high, maybe 40 feet, which would mean it should be easily visible. Reports back then also made it sound fairly frequent, something in the range of two hours.

The old route of U.S.6 used to run right next to the geyser. It's location seems to be visible on the satellite map, and we eventually figured out where that area was visible from our embankment vantage point. It was between a couple of abandoned buildings.

Unfortunately, that area seems to have changed, It seems to have been torn up, with the tan formations disturbed and broken up. It seemed like there was some new (as in the last year or so) piping and plumbing around there, along with a couple of unweathered power poles. This is in contrast to the rest of the area, which has that weathered look. A tree visible in the photos from then appears now must be a stump. And nowhere did we see any evidence of water flowing or pooling or even damp areas.

Were there about 90 minutes before finally coming to the conclusion that the geyser there has been considerably altered, if not destroyed. No point in sticking around.

Green River Observations for 2020 October 16

Made a road trip to visit the cold water geysers of Utah along with the Keller family. I've never been to any before, so was all new to me.

Champaign Geyser is about a 25 mile drive south of Green River, Utah, mostly on well maintained gravel road. The washboarding on the road tended to get worse the farther one went. The feature lies just north of the San Raphael River, and we arrived there to find it in eruption.

It's a drilled well driven by carbon dioxide, with a water temperature barely above the air temperature. The vent is tiny, in the middle of a small semicircular cone built up from mineral deposits. Surrounding that is a broad platform with lots of terracing.

The nature of the eruption is unlike that seen when the water is boiling. The water ejected consists of a column of foamy water thrown to about a meter high, frequently cut off by gas causing droplets to be expelled up to three to four meters. These noisy cutoffs would also cause the formation of small water droplets, so we could even get an occasional rainbow.

The eruption continued for the half hour we were there, considerably weaker toward the end of the visit. Since the intervals seem to be something in the range of eight hours, there wasn't going to be another eruption until around sunset or later.

From there it was backtrack and head to Crystal Geyser. The road starts out as unmaintained but paved, then turns to gravel. Unlike Champaign, we weren't alone. There were a number of campers along the river, and people playing with their motorized toys came and went in waves.

It appeared that the last eruption had been a while, since much of the platform was dry, and there was only a little overflow. There are holes in the pipe making up the vent, and water would periodically flow more heavily from them. The intervals were about seven minutes. The water coming out was slightly foamy. There was visible distortion in the air over the vent from the gasses coming out. The foaming and gas bubbles could also be heard as we waited nearby.

There is a wide platform with numerous terraces and terracettes leading down to the river. These formations seem fairly strong, and some of the dry ones had dead tamarask growing on them, and scalloping was still visible. In the catch basins around the vent were numerous tiny to small rounded pebbles and stones. Most of the formations are a dark red or dark tan.

After a wait of about an hour, we witnessed some short, minor activity. This started with foaming from some small bullet holes in the casing. As the foamy water rose over the next minute, more holes, higher up, joined in. Finally there was some foaming about an inch high or so from the vent, lasting for about a minute. Then everything died down.

After another minor, and about 90 minutes later, activity started up again. This time, the foaming got stronger, and a true eruption started. This consisted of a column of foamy water about six to eight feet high, with a few bursts during the first minutes to about twelve to fifteen feet. At first we thought this might be just a strong minor, but as the activity continued, came to the conclusion that this is now the major activity. After about 20 minutes or so of this, we decided to leave, in part because it was mid afternoon, and the activity had attracted a lot of people.

It was instructive to see how people behaved here, when compared to what is considered normal and proper behavior among Yellowstone's thermal features. The most important difference is that here the water is not deadly. We saw multiple dogs off leash running through the shallow pool surrounding the vent. A few lapped at the water, but not for long, as I'm pretty sure the water isn't pleasant tasting. We saw children playing in it, and tossing the formation stones around. As the major started, there were several small children standing right next to the vent that needed rounding up. During the eruption at least two people doused their heads in the foamy spray. And that doesn't begin to take into account all the people wander all over the formations before the eruption.

Observations for 2020 September 09

Arrived at 07:00 to temperatures even colder than yesterday. Except today it was supposed to eventually be nicer. And it was. There was less wind, which made a big difference.

At around 09:00, for the first time this interval, New Crater/Steamboat started looking interesting. Suddenly there was an increase in the flow down from South Vent, and that was sustained for the next half hour. Only once or twice did the North Vent try to join in, so it never looked like an eruption was about to start. The flow down the runoff seemed to decrease as suddenly as it started.

For the next five hours, there wasn't much going on, and on the whole, it looked a lot like the previous couple of days, except with better weather. Unfortunately, the wind tended to move around a lot, with the middle plaftorm being a prime target. But around 14:30, we got another pickup in runoff. Not as noticeable as earlier, but within the next 10 minutes or so, there was a flood of water going down the runoff channel.

It got to the point were I decided that this was my chance to get a start from somewhere other than the lower platform, so I headed down to the bridge. There I found a torrent of water coming down. Surges were moving debris down into the catchbasin above the bridge. I found it hard to tell what was going on, not being familiar with the view, and the steam didn't help. But after a couple of minutes, it became obvious that either we were about to get the start of an eruption, or we could head home because nothing was going to happen until dark.

We got the eruption, about three seconds after 15:00. The surging built into a pair of water columns that were easily visible because the wind shifted so that the parking lot received a small shower. After a few minutes, I headed up to the middle platform, where it was still dry, and remained so for the duration of the water phase.

Then the wind started shifting so that the upper platform got wet, then the lower, then the switchback, then all the way to the bottom. For the duration of the eruption, the only safe place was the "Decker Island" area, and maybe Echinus.

A couple of hours into the eruption, I noticed that there was a second steaming tree down near the North Vent's runoff channel. I've seen the other steaming tree all summer, but never noticed this spot of hot ground.

September 09, 2020

Observations for 2020 September 08

After yesterday, the cold but clear at Norris as a relief. Except there was a wind that pushed the steam onto the platform and down to the bridge. Not that there was anything to see, but did make for some nice rime ice on the tree next to the platform. The activity seemed unchanged when we left at sunset, although except in the shadows, all the snow and ice was gone.

September 08, 2020

Observations for 2020 September 07

The weather when arrived at Norris was clear and cold. Over the next few hours, the clouds started to appear. The sun made an appearance at around 09:00 and then the clouds made it disappear, so it stopped warming up. At around noon, it started to get noticeably cooler and a north wind started.

That shifted the steam so that it was now blowing down toward the bridge when it wasn't obscuring our view from the lower platform. By 14:00 the precipatation started, and quickly turned from sleet to snow. We left the platform at 16:20 by which time there was about an inch of slushy snow everywhere. New Crater/Steamboat had been quiet all day, and showed no signs of even trying to give us a decent minor. The drive home was the first in a while where there wasn't a notice of an eruption while we were driving home.

The drive back was loads'o fun. There was a continuous line of cars from the Madison Junction to Fountain Paint Pots. Only part of that was because of a bison heard at Nez Perce. There was a tree overhanging the road at the Firehole Picnic area, and a lone bison starting another blockage just north of Biscuit Basin.

September 07, 2020

Observations for 2020 September 06

By moonlight, we could see Rift erupting as we approached Castle. I figured that that meant we would need to wait until Rift ended. Which was the case. First we had to wait through a series of four Turban eruptions to get to the Turban delay. Then it took two more Turban intervals before the eruption itself. At some point between the start of Vent and the time a pause could have happened, Rift quit. The night was mild and only a bit hazy from the smoke, and probably the last nighttime Grand for the trip.

The next One Burst Grand Eruption was even more obnoxious. At a little over eight hours, it turned into the longest Grand eruption interval so far this visit. There wasn't any Turban interval delay, just a series of non-descript Turban eruptions and intervals, with nothing to show for any of them. None of the other vents in the area were active, so they can't be blamed either. The only indication of an impending eruption was that the Turban intervals were getting shorter. After the Grand eruption, I did notice that for the first time in a while, Belgian Pool was down about 2cm.

Beehive had a short Indicator eruption, catching us by starting as we approached Anemone, with the wind in our direction. It took a bit of running and berating tourons to get out into the dry area to the north. At least the umbrellas were useful this time. This was around the time that we were starting to see the smoke plume rising to the south.

It appears that Fan & Mortar are going to have weak events from now until the next eruption. There were two today, and decided to ignore the first, but go on down for the second. The opening of Upper Mortar has been so split that it is now easy to see the end-of-event splashing and roaring down deep in the former vent.

And by this time, the whole southern horizon was a mass of smoke plumes visibly growing and rising. Over at Grand for the final One Burst Eruption of the day, were after one Turban interval we got a two Turban Interval delay. Much shorter than the previous waits. There was a hint of rainbow at the top of the Grand watercolumn, but otherwise it was another windy eruption.

September 06, 2020

Observations for 2020 September 05

Earlier this visit I'd walked north from Artemisia to kill some time. Not much to see along this trail, as the trees are thick and the trail is still an old roadway. But caught an eruption of Cauliflower, and decided I should try to get an interval. Today was the day to do that.

Turns out the interval I saw was 43 minutes, and the duration and size of the eruption was a heavy boiling that lasted about 90seconds. This matches my memories from long ago, so it appears Cauliflower's basic behavior hasn't changed much.

From there headed over to Grand. Had a two Turban interval delay before we got a nice two burst eruption. This time, at least, the eruption was long enough that not getting a third wasn't a disappointment.

Went out early evening for Castle, and managed to have it start while on the bike between the Lodge and the Lower Store. But it was still an interesting eruption. The Lone Star Fire had flared up yesterday, and today was huge. Behind Castle, with its intermittent rainbows, was a huge, billowing black cloud.

Went over to Grand early, and may have missed an early Turban interval delay. As it was, four Turban intervals later, just as the sun was setting, Grand had another long Turban interval. So the One Burst Grand Eruption took place just before it became too dark to see much, two Turban intervals later.

But the real fun of the day was the fire situation. Mid afternoon the NPS closed the road from Kepler Falls over Craig Pass. That this is the Saturday of a three day holiday weekend meant there were lots more people around today, including those who aren't intending to stay in the area overnight. This closure, along with the overpass detour, created a huge traffic mess. The mess was made worse because of numerous animal jams as people stopped to get a selfie of a bison along the road.

At one point, the road from Faithful all the way to the West Entrance was gridlocked. It didn't help that there were people with cardboard signs saying "Old Faithful Closed" encouraging people to make improper u-turns and further block traffic. And, the road near Mud Volcano was again closed to do more cleanup after a gasoline tanker spill in that area. (Who exactly was the genius who decided that work couldn't wait until Tuesday?).

September 05, 2020

Observations for 2020 September 04

Decided that there wasn't much point to getting out to Grand as it was getting light, so surprised to find out that it had a well over seven hour interval. That messed up plans for the morning, so didn't really get out til it was close to noon. Mostly got started because there was some minor event at Fan & Mortar, and wanted to see what was going on, but arrived after everything died down.

As it was, Castle started erupting as I was tying down my bike. It had all the earmarks of being a minor eruption, as it was constantly stopping and suddenly restarting. One pause, around the 4-1/2 minute mark lasted for almost a minute. But by 15 minutes it was obvious that the transition to steam had started.

Over at Grand, it was a short, two Turban interval wait with no sign of any delays. The eruption itself as two bursts, which is always welcome.

From there, wandered back down to Fan & Mortar to kill some time. Nothing much happened. On the way back, noticed that Spa was boiling in the northern vent, and near overflow, waited for a bit, and it finally did get to overflow. But within ten minutes, the boiling had quit, and it was back below overflow. Grotto was quiet during all this.

Went out for the afternoon Beehive (they are all afternoon Beehives). From there it was obvious that the fire to the south had flared up, and was getting bigger as we watched. No smell of smoke yet, but expect that to change tonight. Last night we caught whiffs of smoke while waiting for Castle.

The evening Grand was entertaining in multiple ways. I saw Turban in eruption as I was walking up, and when I arrived, West Triplet was in overflow, ending about a minute later. The next interval turned into a Turban Delay,

At around the 28 minute mark, Grand, which had been having waves, booped. Then over the next minute, it had several more, before starting to drop. Turban finally erupted about 6 minutes later, and Grand was low. I made a few notes about the activity, taking about a minute, and when I looked up, Grand was not only full again but having another boil. That lead into an explosive start for Grand.

With the sun low, there were some nice rainbows. And it was a pleasant surprise when Grand quit at the 8m24s mark. Except it really didn't try to refill, and then drained, making this one of the shorter eruptions I've seen.

We waited a bit for a possible afterburst, but Grand gave no sign of that happening. So it was about seven minutes before I got down to WestTriplet. It was in a heavy overflow, with thumping and large waves being generated over the vent. Also, a brochure which had been sitting in the vent area for several days finally started to fall apart, with lots of shreds being circulated by the convecting. None of them were escaping down the runoff.

Over the next six minutes, the thumping and upwelling got stronger, and we started getting small splashes. These quickly built into splashes that I consider to be eruptive activity. Then about three minutes later the splashing got really strong, and continuous, and it was obvious that West Triplet was in a full eruption, the first since 26 Aug. During all this, the remainder of the brochure finally drifted into the vent, and it became part of the shreds being circulated.

It was only three minutes later that Rift started. This seemed to start out slower that the typical Rift eruption, and I wouldn't have been surprised if it had been one of those rare eruptions that never overflow. But it too got stronger as the eruption progressed, and the runoff looked normal.

I've seen Grand have this sort of "low pool eruption" before, but this is the first time I can remember actually seeing West Triplet come out of a dormancy period. Interesting that the eruption started in a way (very gradually) that is much different from normal, and how Rift came alive so much faster than normal.

Went out before midnight for another Grand eruption. The smoke filled the basin, not quite as bad as some of the geyser fogs, but still not pretty. While waiting for Grand, at one point Rift started steaming heavily, and making rumbling noises at depth. This lasted for about four minutes, at a time when Sput D was active. An interesting followup to the earlier eruption.

This Grand eruption had a first burst that lasted 7-1/2 minutes, and the whole eruption was only 9m06s. The second time in a row that we were cheated out of a burst.

Also, the bison have made their reappearance, choosing to use the roads to move around, causing lots of problems.

September 04, 2020

Observations for 2020 September 03

With the weather still nice, went out for another moonlit Grand eruption. This time we got a Turban Delay, but Grand managed to erupt anyhow, and gave us a second burst.

It was still pretty cool out when started waiting for the next One Burst Grand eruption. Castle started as we walked up toward Crested. Waited for an eruption that never looked like it was going to be a minor eruption.

After Grand and Castle, decided that wasting time at Fan & Mortar was the thing to do. In two hours (a full Daisy interval) nothing much happened, which is not surprising since the previous eruption was only a few days ago.

Beehive had it's regularly scheduled afternoon eruption, and after that I saw a Bulger major eruption that had a brief moment of water visible in the Hole. The last 90 seconds or so of that eruption had Bulger stopping briefly, even starting to drain, only to start back up. The Grand eruption was after a two Turban Interval delay, and did give us a nice second burst.

It seemed like a good idea, to go out at sunset and catch one of, and maybe both, of Fountain and Great Fountain. Arrived to the Lower Basin and just as we turned into Firehole Lake Drive, heard a call announcing the start of overflow. Pulled up and sure enough, there it was. That gave us a timeframe for visiting Fountain. Over there, nothing happend during the time we had, so we returned to Great Fountain to catch it, and maybe, if lucky, return for the end of Fountain.

Arrived to find a vent that was barely in overflow. Turns out right after we left, there had been some sort of major drop, and the overflow had only just restarted. So waited, and watched for Fountain. Which also took its time. Well after sunset before it erupted, and still no Great Fountain heavy boiling. Fountain finished and we were still waiting. It was almost completely dark before we finally got "the big boil", and then had to wait almost eight minutes for bursting to start. Fortunately, the crowd there was well behaved, and no one had the genius idea of illuminating it, so we got to see the bursting silhouetted by the last light.

On the drive back, past Hot Lake, the car in front of us suddenly stopped. Odd, but then we saw why-- there was a badger crossing the road and headed toward Narcissus.

By then it was almost time to go to Grand. It seems that it had a Turban delay as we arrived, and we finally got the One Burst Eruption four Turban intervals later. On the second Turban eruption, we even got a long, heavy overflow, but not enough to be a Delay in its own right.

Finally decided since Grand was so late that we'd not try for the next one before dawn, but wait for Castle. After over half an hour, it finally started. Then quit for a short minor eruption just about the time we got into position to enjoy the moonlight on the water column.

September 03, 2020

Observations for 2020 September 02

Update: Added photo.

With a bright full moon and no need to go to Norris, it was time to see Grand in the dark instead of just hearing in. Came out and waited just two Turban intervals for a nice One Burst Grand eruption,

While waiting for the next eruption, I noticed muddy footprints on the wet boardwalk. Between the rows of benches on the north side were a faint line of paw prints, about 8 to 10 cm across. There was a second set on the main walkway area. They both appeared at the north end, crossed over the runoff channel, and disappeared at the sign location.

It was supposed to be a windy day, and already there was a strong, cool breeze moving the steam around during the One Burst Grand eruption. In the afternoon we did have to endure a four interval Turban delay for what was pretty much a repeat.

The final Grand of the day was again in the dark. There was a small crowd gathered, including people who had just seen Castle have one of its pause-type major eruptions. Many of those drifted away during the several Turban eruptions we had to wait for. But the conditions were fairly warm, for September night, despite the steady wind. Grand finally rewarded us with the fourth One Burst Eruption of the day.

Of interest is that West Triplet still hasn't erupted in over a week, and each eruption of Grand was followed by a strong overflow from it. And, as noted before, the fluctuations in Belgian seem to have stopped. There is even some runoff coming down from Crystal at times.

September 02, 2020

Observations for 2020 September 01

Day started cold, but not as cold as the forecast. At Norris it was overcast well into the morning, so it never really warmed up until around noon.

Of course there's no fun in finding out that you wasted another day in a place you don't particularly like only to have the geyser you waited for erupt as you were near Madison Jct. just as it got dark and cold again.

September 01, 2020

Observations for 2020 August 31

A cold, wet day where the original plan was to head to Norris. Except based on the reports and instruments, there wasn't any reason to go and kill a day there. So instead it was spent mostly staying warmer and drier.

Did head out for a couple of Grand eruptions, The first One Burst Grand had an interval just under six hours, and there were only light sprinkles during the wait of a couple of Turban eruption intervals.

The evening Grand was dry, but conditions seemed worse. It looked and felt like October, with a cold wind and gray, low overcast clouds and everything steamy. But Grand cooperated, and gave us a nice second burst after a short 8-1/2 minute first burst. And once again, West Triplet came up to overflow, but did not erupt. Also I've noticed that Belgian Pool still has not fluctuated much in the last few days.

Made an attempt to see Great Fountain, as it was near the end of the NPS window. But when we arrived, it was not even in overflow, and it was going to get dark in about an hour. With the heavy overcast, no chance of any sort of sunset light show, so we left.

August 31, 2020

Observations for 2020 August 30

Checked out Oblong, just in case, but it was full and overflowing. The Giant Platform was mostly dry, with a few puddles probably left over from the rains the other day, or some big Giant surges. Over at Daisy there was a normal eruption.

Grand had another one of its fifth hour Turban Interval delays, but this time instead of making us wait for an hour, it had a second delay and then erupted. It was another two burst eruption, and Grand's vent held up for about fifteen seconds before draining and and immediate quitting by Vent & Turban.

Wasted some time at Artemisia, then went on down the trail to see if anything was visible. While most of the interesting features are completely hidden, I did see a Cauliflower eruption that had about a meter boil at the beginning, then a few more boils before dropping back down.

The weather deteriorated for the late afternoon Grand wait. There was a consistent 15-20mph wind the whole time, and despite the sunny, clear sky, it felt cold. No delays, and the interval was less than six hours. There was a large boop from Grand a couple of seconds before the eruption started with a bubble bursting. There was a rainbow coming and going the whole time as the wind shifted the spray that was headed toward Rift. We also got a second burst, a long one so not chance for a third. The surprising thing was that despite the eruption lasting over 11-1/2 minutes, Vent & Turban didn't quit.

Once again, West Triplet showed no attempt at erupting, just heavy overflow after each Grand eruption. Now over four days since and eruption, and even longer for Rift. During this time it also seems like Belgian has been full most of the time, and not shown the fluctuations and drops seen earlier.

In the Lodge Cabin area, the NPS has the fire crews doing some tree thinning within ten yards or so of the cabins. Lots of smaller trees are being removed, and branches from some of the larger trees, too. No evidence they are going to clean up all the deadwood littering the area, though.

August 30, 2020

Observations for 2020 August 29

More Grand eruptions today. Came out at the 11 hour mark no knowing when the previous eruption had occurred. Was at Belgian when Turban started, and moments later saw what appeared to be a Grand Boop well over a meter high This was followed by another, maybe two meters high. Finally Grand started a One Burst Eruption.

Turns out the NPS had the electronic time (around 04:15), but never got around to publishing that information. Typical.

Later spent a hour at Fan & Mortar where I saw nothing but Garbage Mode, with the vents starting and stopping several times during that period.

The after ended the string of short intervals at Grand with a four Turban Interval delay. Once again this eruption was followed by overflow from West Triplet without an eruption. It's now been over three days since its last recorded eruption.

The night was warm, with a clear sky and a bright moon. Probably arrived just in time for a Turban Interval delay. This Turban duration was long, and the next interval didn't have overflow. The delay turned out to be beneficial, because before the next Turban eruption, Oblong erupted.

In the dark, it seemed like the Oblong eruption was short in both height and in duration, but could definitely see bursting and hear it. Several others went down for a closer look, and got there before the end. During the subsequent wait for Grand, it seemed at times like the steam picked up down there, but no followup eruption.

The One Burst Grand eruption was pretty standard for one lasting about eleven minutes. But during the eruption, I noticed Churn splashing, backlit by the moon with heavy steam. Was over by the time I got past the trees at Rift and Bulger, so I returned to Grand.

This time, West Triplet did not even overflow following the Grand eruption. It's now been well over three days since the last eruption of West Triplet was observed.

August 29, 2020

Observations for 2020 August 28

Went out in a foggy Upper Basin with the expectation of waitiing a few hours for Grand. Turned out it was less than one, although that was a two Turban Interval delay. The eruption itself was my third consecutive two burst eruption, which is something I haven't experienced in quite a while. The second burst had a distinct false pause about a minute in, but instead restarted and lasted for another minute. During the eruption West Triplet overflowed, but I don't know if it actually erupted.

In the afternoon we finally got back to having One Burst Grand eruptions. I think this was probably a four Turban Interval delay, but can't be sure. The first Turban eruption I saw lasted over six minutes, which is a good sign of a delay, and the next interval had no overflow.

It was an all Grand day, it turned out. Went out after dark for the moonlight One Burst Grand eruption. This one was short, less than ten minutes and Vent & Turban seemed to quit at the end for well over a minute, then came back without a pause in Vent.

August 28, 2020

Observations for 2020 August 27

After came in last night, the thunder and lightening started. There was more in the early morning hours, which meant there wasn't much incentive to get out despite Giantess still being active. This rain did have the nice effect of getting rid of most of the smoke in the air, although there was still a hint when I first got out and about.

Thanks to an electronic time, knew that we were actually well into the interval as we headed out for the One Burst Grand eruption. I noticed that Sawmill was perhaps even higher than noted earlier this visit. The catch basins may have been just rainwater, but hard to tell. At Grand only waited for one Turban interval. After the eruption, West Triplet was overflowing heavily for a while, showing no attempt at erupting.

On Geyser Hill, waited through a rain show to finally get some daylight activity from Giantess. At over a day, it was still bursting nicely. Infant was still boiling heavily up to a meter, and it smelled almost exactly like Emerald Pool at Norris.

Walked around to check out Plume. The only difference was that the water level was actually visible in the two front/lower vents, and the deep sputtering was visible and sounded a lot wetter.

For the afternoon Grand, there wasn't any attempt at a Turban Delay. We also had a relatively short first burst and a quick second. After this eruption, West Triplet didn't try to overflow.

The early nighttime eruption also had two bursts. Caught us by surprise, as the interval was under 5-1/2 hours. But it had two bursts, and again, West Triplet overflowed after the Grand eruption with no attempt at erupting on its own

August 27, 2020

Observations for 2020 August 26

After last night's fiasco, headed back to Norris when we found no report of any eruption. This time not only was it dark, but foggy as we pulled into the parking lot. The fog got worse out in the basin, such that as the sun rose, it was difficult to see from the platform what was going on with the vents. We did know that there was some sort of push around 07:07 that got us excited, as if it was starting to erupt. But nothing.

And that was the way it went for the rest of the day. There would be what appeared to be the start of the push from the North Vent, only for the South Vent to take over.

Around 11:00 we got a radio call informing the gathering that Giantess had started erupting a couple of hours earlier. There was general disappointment with this, but no one left to head back south the the Upper Basin.

At around 17:15, I went down to Cistern to take a look at what it was doing. It wasn't overflowing much, even though the boiling over the vent was fairly heavy. The day had been so disappointing that I was considering leaving to got and see some of the activity of Giantess. As I rounded the last hairpin turn and got within sight of the platform, New Crater started another push that actually got the inhabitations shouting. I started video recording, and made my way back to my chair as this push died. I left the camera running, fortunately, as a second push started a few seconds later, and this one led to the actual eruption at 17:36.

I rushed back to get a height measurement. I got 65% of 130 meters, or 84.5meters (277ft). This matched the impression of those who saw the start from a distance, that it wasn't one of the taller eruptions.

The wind direction was perfect. Most of the parking lot was spared being drenched, and we never were in danger of getting wet. If the wind had been a bit more to the north, we probably would have had a dirtier eruption, and perhaps even a choke. As it was, North only showed a hint of brown for a while.

Stayed for about 90 minutes, until the clouds and wind shift encouraged us to leave. Got back to the Upper Basin with it not quite dark, and headed over to Geyser Hill. The parking lot was mostly dry when we left, although the exit end loop was damp along the edges.

Did the loop around the hill before heading over to the benches near Vault. At Plume, it looked like there was quite an area that had gotten wet, but Plume itself sounded unchanged from what I'd seen earlier. Over between Depression and Heart I thought I caught a whiff of low tide. I expected more, considering there had been quite a bit of time for grass to grow in the various runoff channels.

Caught a couple of Giantess active periods, and an eruption of Vault. Most interesting was the activity of Infant. It was well above the rim, and the muddy looking water was boiling and erupting up to a meter high almost continuously. It also had a sweet smell a lot like Emerald, not the putrid smell I normally associate with it.

Observations for 2020 August 25

On the drive to Norris in the dark, had a bison encounter. It was standing in the southbound lane in Fountain Flats just across from the Thud Group. It didn't move until was right next to it, despite flashing lights and honking horn. Other than that, the drive was uneventful.

When we arrived there was someone on the Upper Platform, prone and in a sleeping bag. I rudely woke him up and he quietly disappeared.

Uneventful also describes the day at Norris. There was a datalogger report of something big happening around 03:00 and New Crater/Steamboat was in some sort of recovery mode the rest of the day. Most of the activity consisted of strong North Vent activity which shut down when South Vent joined in. Only late in the day did it start showing real signs of life, with the biggest attempt right as everyone was headed out ahead of darkness and a windy storm and a stream of incoming drunken louts. Even then, despite the mass of water from South, the North Vent would die instead of getting stronger.

Which brings us to the big event of the day. During the drive back to Old Faithful, it is always fun being cut off from any information about what is happening at Norris for almost an hour. So the first thing anyone does, with a certain amount of dread, is check to see what happened at Norris during that time. I've been fortunate in that until tonight, I've not had to see a posting saying I've missed an eruption.

Except tonight's posting had a time that made no sense. It only about an hour old. I double checked my logbook, and supposedly the eruption started just as I'd left the platform. It always takes at least fifteen minutes to uncover the truck and head out, so there was no way this report was accurate. I flagged it immediately.

Needless to say, quite a few people saw this report and got upset by it. The report was not appreciated and caused a bit of anger at the sloppiness that got it posted in the first place. People who report this information need to remember that those of us actually here in Yellowstone rely on GeyserTimes for accurate information, and it is the duty of those making reports to insure they are accurate before making them. There is nothing to be gained by attempting to be "First!" if that information is flat out wrong, as it was here. It's not a game.

In the morning I expect to check GeyserTimes and see if I need to head back to Norris, or if I can sleep in. I want to be sure I can trust that info, and not have to independently confirm it at a time when I am barely awake.

As mentioned earlier, it was stormy on the drive back, with occasional showers. Unfortunately, it appears that there really wasn't enough rain to have an effect on the fire, and the wind was probably not helpful.

August 25, 2020

Observations for 2020 August 24

Arrived at Norris at dawn, not really expecting much until the afternoon. Turned out to be late afternoon, with over a period of 20 minutes there being three significant attempts at erupting starting around 16:27. There was a second, even better period starting just about the time to leave, with three more attempts in a period of six minutes starting at 20:13. Then nothing as it got dark.

It was hard to tell the smoke from the clouds during the day, although by evening there was some patchy blueness to it. Back at Old Faithful, the smoke could be seen as fogginess and was definitely a smell in the air.

August 24, 2020

Observations for 2020 August 23

The fires didn't dominate the day. The general smokiness wasn't changed much, but this morning there was a definite smell of burn wood in the air that disappeared as the day progressed. It wasn't until about noon that the plume of smoke from down south became obvious. By evening it would have been clearing if not for the local fire.

The morning Grand was a Turban Interval delay, and it was on the third Turban eruption that we finally got the One Burst Grand eruption. That burst lasted just over 9-1/2 minutes, then Grand held water over the vent for nearly a minute before draining. With that, Vent & Turban also quit.

The afternoon saw another Turban delay, this one for five intervals. Grand finally erupted as West Triplet quit. Fortunately, we got a second burst this time. With a first burst lasting less than eight minutes, we definitely expected one. That burst was fairly short, and Grand showed no attempt to have a third, even though the duration was still under ten minutes. Again, Vent & Turban quickly quit once the eruption was over.

One interesting non-thermal item of the day were the otters just below the Sawmill bridge. They were seen first just after the morning Grand eruption. They got out of the river, only to disappear into one of those dead holes just upstream on the west side. The grass looks beat down between that hole and the river, like they've done that before. They weren't seen the rest of the day,

August 23, 2020

Observations for 2020 August 22

Went out early for Grand based on a double interval. Didn't find out until later that the first interval was particularly long, and we'd arrived not much after first overflow. No delays, but the One Burst Eruption had an interval of about 6-1/2 hours.

The mid-day Grand was similar. A Delay Turban was followed by three Turban intervals before we finally got the One Burst Eruption. This one also lasted just under ten minutes.

After Grand, decided to go to Artemisia to kill some time. Walked up, dropped my pack and started to get out the water bottle when I felt the first thumps. Unfortunately, the wind was pretty strong, and shifting, so there wasn't any place to stand where one didn't get the full force of the steamy fog. And it was hot.

Returning from there, glanced at Fan & Mortar, and they looked dead. By the time we got to Castle, there was a radio call about splashing in the Main Vent. Went back, and there was some huge splashes, as wide as the vent and well above the highest part of the rim. Unlike yesterday, Bottom Vent didn't dominate, but even so, the Fan vents started out nice but by the time Angle Vent started, it was obvious that there wasn't much of a chance for an eruption.

After the Fan & Mortar event, noticed that there was a large smoke plume to the south among the general haze. Turns out there's a small fire near Lone Star. The NPS closed the trail and evacuated the campsites by helicopter. We had intended to go out that way tomorrow, looks like that is off.

Went out for a Grand in the dark, and had the place to myself. Interval was just under six hours, and no signs of any sort of delay. Best of all, Grand quit at just over eight minutes, and followed up with a nice illuminated second burst. Total duration was only 9-1/2 minutes, so could've had a third if it had tried.

August 22, 2020

Observations for 2020 August 21

Another smoky day, but not quite as bad as yesterday morning. By evening most of the smoke seemed to be thickest to the south, down in the Tetons and Jackson.

Went out on a double interval for the One Burst Grand eruption, and got a full Turban Delay interval. So that was probably the shorter of the two intervals.

Checked out Daisy, which had another short duration of around 3m15s. Over at the Sawmill Group, saw Crystal in overflow, along with Belgian actually up to and over the rim. I still can't see any correlation between the water levels there and the activity elsewhere.

The mid-day One Burst Grand had to have a five Turban delay, again showing the bimodality in the intervals. The call that Beehive's Indicator was erupting came after about three intervals. So many left for the sure thing. Fortunately for them, Grand held off so that we had a total of five intervals in the Delay.

Later in the afternoon, Fan & Mortar had a nice attempt at erupting. There were some Main Vent surges that filled the vent area. Lower Mortar had a high water level too. But Mortar's Bottom Vent was dominating, and it lasted a long time. I don't like seeing that, and it always seems that Fan's response to strong Bottom Vent is weaker than desired. That was the case here, where the excitement evaporated at the activity died out as Angle Vent started.

So went over to Grand for the evening activity. There it seemed like I missed a Delay, based on the long Turban duration and the lack of overflow before the next Turban eruption. West Triplet started at the same time as Turban, and that led to a true Delay. West Triplet's duration was short, so it was a surprise that almost immediately Rift started. And then the One Burst Grand eruption started. I had been prepared for a long wait, with an eruption in the dark, so this was a nice relief to see it just after sunset.

August 21, 2020

Observations for 2020 August 20

Woke up to an orange sky, and not needing to go to Norris. Seems that fires in California are having an effect here. Another example of how California has to inflict itself on the rest of the country.

Having a Beehive eruption before noon was a bit of a surprise. Was a nice eruption because it was dead calm. The winds picked up minutes after the end, and lasted all day.

I don't know if the mid-day Grand had a Delay, as the Turban activity didn't match what I would expect. West Triplet was erupting with everything erupting behind it when I arrived. It was five Turban eruptions later that Sput D had a small erupion, followed by the One Burst Grand eruption.

Later caught a Daisy eruption in the wind, a two hour interval. That was followed by watching Spa for about 45 minutes. It had multiple large bursts. Nothing high, but lots of wide, sustained activity.

The evening One Burst Grand didn't require much of a wait. Rift was erupting as I arrived, and was still erupting when I left. This time Grand did have the Turban Delay. About 2-1/2 minutes before the eruption booping started, with the pool full but calm. It wasn't until there was a big boop that the waves started and Grand then quickly followed. Because of the smoke and lighting, it was a gray eruption on a smoky background.

August 20, 2020

Observations for 2020 August 19

When the NPS says they are going to open an area at a given time, they mean it, even if the press release implies that they might open early. So we arrived into the Norris Basinat 10:00 instead of the usual dawn. Waiting for the lot to open was mildly entertaining, watching how people behaved to suddenly finding they needed to make a decision on what to do instead. As for the closure, it didn't matter, as New Crater/Steamboat didn't do much for most of the day.

Late, as the thunderstorms were starting, we did get the first strong minor that I've seen this summer. That was followed at about one hour intervals with other strong surges, but no actual attempt at erupting.

In my decades of coming here, I've seen a lot of geyser gazers who have disappeared or drifted away over those years. I do wish that Dave Leeking was one of them.

A while back I wrote up some advice and hints and observations for newer gazers. Here's something new to add, based on what I observed yesterday-- Don't go around telling vistiors you just met about the wonders to be found in areas closed by the NPS. Especially then don't go and give them detailed instructions on how to get into those areas and how to get around the NPS closure signs.

August 19, 2020

Observations for 2020 August 18

It was exactly twelve hours since the last Grand eruption, and I had just passed Crested Pool when the One Burst Grand eruption started. Must've gone on the Turban delay.

Afterwards, noticed that it was getting close to the time for Daisy. Kept looking back as walked to get the bike, but no eruption. Had just left the bikerack when l heard the radio call.

Did get up there for the next eruption, which had an interval of less than two hours, but a duration of 3m11s, which is really short as I remember.

The next wait for Grand didn't have an official Turban Delay, but it acted like one. The first interval seen was about 24 minutes long, and then Grand proceeded to have Turban intervals with all the usual delay characteristics-- short Turban duration, short intervals, and little to no overflow from Grand. This time, though, Turban started the eruption, and there was a nice second burst. It was a long pause, so the crowd had plenty of time to get out of position for their selfie-photos of the second burst.

West Triplet started at the same time as the Turban eruption prior to Grand's eruption, and continued on even after Grand was finished. This meant the duration was up to 1/2 hour, and as expected, Rift started shortly after. West Triplet was still going when I left, for a duration in excess of 45 minutes.

Got the call for Beehive's Indicator, and despite the wind knocking it down, it was a nice long one, nearly five minutes. The crowd was small, despite the Naturalist telling people about it. Seems most people were more interested in getting over to Old Faithful, which erupted shortly after Beehive.

August 18, 2020

Observations for 2020 August 17

Went out for the dawn Grand eruption when it just became light enough to not need a light to take notes. I didn't see a Turban delay, but then next four Turban intervals looked like there had been one, with some eruptions with no overflow, and short intervals between Turban eruptions.

When Grand did start, it was nicely lit by the sunlight well above the ridge. And we got a second burst, which made it even better.

The other day I noticed that the old stairway up from the Sawmill Group Bridge is being covered by formations deposited by South Scalloped.

I arrived back at Grand just in time to see Rift starting, and West Triplet ending. This was the folllowed by a 36 minute Turban interval for another Delay. Rift proceeded to erupt for almost exactly two hours, ending near the start of the four Turban interval delayed One Burst Grand eruption. This one had a short Vent & Turban pause. Belgian Pool also was full at the start of Rift, and full after Grand ended.

In the evening we got another Turban delay. It would have been a nice Grand eruption, with the sun low on the horizon. But had to wait two more Turban intervals for a One Burst Grand eruption right after the sun finally disappeared.

August 17, 2020

Observations for 2020 August 16

Down by Fan & Mortar saw an osprey gliding upstream. It perched on on the top of e of the trees beside Link's runoff channel for a while, then suddenly launched itself toward the river. Unfortunately, it came up empty. It then cirlcled around a bit, and we thought it might return to the tree, but it headed upstream. About five minutes later, it reappeared low over the river, headed downstream with a small catch.

Up at Daisy, nothing much different. The duration of the eruption was short, although the intervals were just over two hours. Lots of Side Boiler activity in Splendid, and I left just as the activity switched to Main Vent.

The One Burst Grand eruption managed to have both a Turban delay and erupt almost outside the NPS prediction window. Just two minutes in. The delay was around 5h10m and had several small boops, so I wasn't surprised when it immediately dropped.

At Beehive, the wind was directly toward the walkway the whole time the Indicator was erupting. Just as Beehive started, the wind shifted to spray the walkway and platform on the other side of the river, and stayed that way for the duration of the eruption.

Went to Three Sisters Spring to watch Mugwump for a few hours. It was erupting about every twenty minutes. Most eruptions were minors, where there's one big burst and some other boiling, and the whole eruption lasts less than ten seconds. Did see a couple of major eruptions, with multiple big bursts, and a lot more overflow that lasts for a bit under 1/2 minute. The last one we saw was the best of the day, with a flood of water coming done.

Myriad #1 also had a couple of small but heavy boils during that time.

At Grand the Turban interval went long. Grand's pool was full, and over about 45 seconds, there were six to seven small boops. There were never really any waves, despite what Grand was doing. Then the pool dropped and stayed that way until Turban started about six minutes later. I was making notes when I looked up to see the pool back to full, with waves. No boops this time, but instead got a quick start with a nice bursting bubble. The rest of the eruption was a pretty typical One Burst Grand, although it lasted almost twelve minutes. At first it looked like Vent & Turban were going to continue, then suddenly Turban got a lot stronger for about fifteen seconds, and then abruptly quit. So much for any afterplay and an afterburst.

Finally, it was time to wait for a sunset Castle eruption. The rainbows were just starting to be visible at the top of the water column from our vantage point.

August 16, 2020

Observations for 2020 August 15

Grand definitely seems to be in a mode where it is having four to six Turban delays if it doesn't erupt then. I didn't see the delay this morning, but all the Turban intervals and durations matched what I have seen after the other ones of the past few days.

This eruption itself had two bursts. The conditions were about a good as they get. It was late morning, so the sun was still backlighting the eruption as seen from the northern benches. There was no wind, and the sky was blue to the ridges. It was almost as perfect as 90% of the reported Fountain and Great Fountain eruptions are described to be.

Checked out the Fan & Mortar area. Nothing much exciting there, although there is no garbage mode, but definitely cycling. Noticed that the Link runoff culvert has a lot of dried and dying slime mats, implying that it's been a while since the last strong minor eruption.

The afternoon One Burst Grand fit the pattern. There was a 30 minute long delay Turban interval on which Grand erupted three minutes into the window.

August 15, 2020

Observations for 2020 August 14

This time of year, arriving at Norris at 06:00 means it's still dark. Last month it was light for the drive from Madison Jct.

The parking lot was empty when we arrived, and over the next few hours a few people filtered in for the wait. The wind of the previous few days was gone, the sky was completely clear and there was little precipitation onto the platform.

The wait was pretty dull. No longer does it seem that New Crater/Steamboat has big, notable minors. Instead, the only sign of any progress seems to be that the South Vent becomes more voluminous and the platform to the left becomes wetter.

I'd just returned from a parking lot run less than ten minutes earlier, and was starting to read a book when suddenly the activity picked up. As with the 2020 August 03 eruption, there was no warning. Within seconds, the eruption was starting.

This eruption start seemed wider and not as tall as others I've seen. The wind direction was toward Echinus, so we never were in danger of getting wet. It took a while for the water to start down the North Vent's runoff channel, and none of the other channels under the switchback had water. North Vent only briefly went slightly gray, then was back to clean. Few rocks were thrown.

Later in the evening did go out for a nighttime One Burst Grand Eruption. It lasted long enough to insure no chance of a second burst.

Update:
Forgot to mention that on the drive back from Norris, I did see something erupting in T.Scott Bryan's Tangled Geysers group. I always glance over that way assuming the traffic allows for it. The feature was at least a meter tall, looking a lot like Old Tardy, and active the whole time it was visible.

August 14, 2020

Observations for 2020 August 13

I figured getting out to Grand after a double interval of twelve hours would mean I'd get to wait a bit. Instead, I was at Belgian when the One Burst Grand eruption started.

From there it was a quick check to confirm that the Giant platform was completely dry and ignorable for now. Also wanted to look at Fan & Mortar, who had the start of a nice, normal cycle. No garbage mode that I could see.

Leaving there, I noticed that Grotto Fountain was bubbling. Didn't have to wait long before the pressure pool was suddenly full of water and almost to overflow. It was a ten minute long eruption before Grotto started, and it lasted over 21 minutes, ending suddenly. There was also activity from South Grotto Fountain before and after Grotto started.

The day started out breezy, and was extremely windy by the time for the next Grand wait. I had to wait almost half an hour to see my first Turban eruption, and it was six more Turban intervals before Grand finally erupted. The behavior was similar to yesterday's two long delays.

But we got a reward. Grand quit at around 7-1/2 minutes, then we got a short second burst start thanks to the wind. It looked like after about a minute that it would stop, but at that point the burst settled into nearly three minutes of Big Sawmill Mode. The followup West Triplet lasted only 26 minutes, but the restart was after that.

It was still windy in the evening, and cloudy so there wasn't any chance of a sunlit eruption even if it went early. As it was, arrived at what was probably near the start of a West Triplet eruption. As it erupted, Grand looked good much of that time. So once again we got an early delay.

Fortunately, it was only a two Turban interval delay until the One Burst Grand Eruption. Was enough light to see it. Would have been cooler and darker if it had waited.

It's amusing that it appears Grand has been bimodal the last few days, mostly erupting outside the NPS window on either side. Even this evening's eruption fits in, in that it tried to erupt early.

August 13, 2020

Observations for 2020 August 12

The middle of the night One Burst Grand eruption continued the number of short intervals I've seen recently. The sky was overcast, so not much opportunity for any meteor observing.

I did have to wait a Turban interval, but that one ended with another of those Turban starts where it just feels like Grand wants to start. The power of Turban, combined with the hint of steam getting thicker over Grand proved to be correct. That eruption was one of those with several minutes of Big Sawmill, padding the duration out to 12-1/2 minutes.

West Triplet started before the eruption, and right after Grand finally quit. Rift started.

Went out again in the morning for the next One Burst Grand. It was overcast, breezy, and cool. Got a Turban Delay with the first Turban eruption after arriving. This one even featured a small Grand boop several minutes before Turban started. Right after the boop, the pool dropped and kept dropping.

Ended up having a six Turban delay, although if one of the intervals had been about 30 seconds longer, it would have been a D2/D4. Several of the Turban intervals featured weak or no overflow from Grand, and short durations for Turban. It finally erupted on a short Turban interval where the pool was full by eleven minutes and then kept slowly filling with lots of waves.

The pool drained after the first burst, then refilled. It sloshed for over a minute before until Vent started having some powerful jetting, signaling the end. With the draining, Vent & Turban quit almost immediately.

Also got to see a Churn eruption from the benches right before the first Turban Delay. At some point, would be nice to see one up close.

The afternoon One Burst Grand was almost a repeat of the morning's activity. There wasn't a threat of rain, but it was overcast, cool, and windy. The interval was slightly longer even though the Turban Delay was for five intervals instead of six. West Triplet was ending an eruption as I arrived, and it started again during the Grand eruption.

All three Grand eruptions today were outside the NPS prediction windows. The first was before, the later two were after.

August 12, 2020

Observations for 2020 August 11

It was a day to do things outside the thermal areas. Although, I did visit Mud Volcano for about an hour for the first time this century. Took some video which will have to wait until September to get posted.

Did go out after dark for the One Burst Grand eruption. Expected to wait a while, instead got an interval under 5-1/2 hours. That's four eruptions in a row where I've waited less than a Turban interval.

August 11, 2020

Observations for 2020 August 10

Found out during the night that there was no need to go to Norris. Woke up to find that Fan & Mortar had finally erupted. Out at Grand, waited 30 minutes for Turban to finally start. Grand's pool was low at the time, but quickly filled and we got a One Burst Eruption with an interval of less than six hours.

The next One Burst Grand eruption was also on a short interval. Arrived for the last minute of a West Triplet eruption, and Grand started less than 15 minutes later.

After that, spent mid-afternoon waiting on Geyser Hill, since Beehive has been having one day intervals this week. Turns out in quick succession, we got Lion and Beehive eruptions, and then, after about ten minutes, an Aurum eruption.

The final One Burst Grand eruption of the day was also a Turban Delay start. I didn't see the previous Turban eruption, but it had been over 25 minutes when Grand had its first boop. Over the next 80 seconds, there were several of them, some to 2 to 3 meters in height. Finally, one of the boop went from boiling to jetting, and the eruption started.

So I saw three Grand eruptions today, and didn't see any Turban intervals, but did see to Turban Delays.

August 10, 2020

Observations for 2020 August 09

Another day pretty much like the previous. Again, there was some nice activity from New Crater/Steamboat during the morning, but by afternoon it had settled into a mode where it looked like it was trying to start, but as soon as the North Vent started to build, it would die down instead.

I also didn't get to see the bear that wandered up Tantalus Creek and headed off toward the parking lot.

August 09, 2020

Observations for 2020 August 08

Arrived at Norris in the dark. It appeared that New Crater/Steamboat was much improved from yesterday. But that only lasted until mid-morning. As the day progressed, it regressed. When we left just before sunset, the activity seemed to be little better than what we'd see yesterday. The platform and rocks around the South Vent were dry, as well as the back runoff channel. A disappointing day.

August 08, 2020

Observations for 2020 August 07

Spent about an hour and a half at Norris to confirm that it was way too early for a Steamboat/New Crater eruption. The activity was even quieter than when we arrived for the previous eruption. Based on this, we figured there was at least six to eight hours before the chance for an eruption, and left.

Got back just in time to head out to Grand. The interesting things about the morning One Burst Grand eruption was the way Vent and Turban died down to almost nothing, then came roaring back. Stuck around for the possibility of afterbursts, but the afterplay didn't start for over ten minutes.

Mid-afternoon Beehive eruption had a slow start, with about ten seconds of large surges to about 5-7 meters before actually starting. But despite the wind, it was a nice tall eruption.

The afternoon had another One Burst Grand Eruption. This time Cent & Turban did quit, and it took nearly 24 minutes for them to restart. Once again there was a short, 6 minute West Triplet eruption after Grand quit.

August 07, 2020

Observations for 2020 August 06

Was probably the last opportunity for a moon-lit Grand eruption, so went out even though the high clouds scattered the light so that there weren't sharp shadows. Unlike most nighttime eruptions, the breeze for the One Burst Eruption was not to the north, so the eruption was nicely visible from the wooden benches area.

With the parking lot scheduled to be gone next year, a trip out to Imperial was fairly high on the list of things to do this year.

We got a later start than intended, and the lot was well over half full by the time we arrived around 09:00. There were considerable number of people going beyond the overloop not just to Fairy Falls, but to Imperial. The whole hour we were there, there was at least another group present.

Imperial erupted continuously whiile we were there. Some of the bursts were huge. From where we were at the last trees before the mudpots, some of the water was visible well above the ridgeline. If my math is correct, these bursts were around 12.5m (45ft) high.

Also watched Spray coming and going. Didn't get intervals, but did see it slow down each time, stop for perhaps 15 seconds, the slowly restart.

Arrived back to the Upper Basin just as the Grand eruption window was opening. Went out and there was already no room on any of the benches, except one wooden one at the very north. Once Vent started, I made my way down toward Rift, as the spray from the wind, while not reaching the boardwalk, was obscuring the water column. Did get a second burst, a nice tall one. And Vent & Turban didn't quit afterward.

Not much to say about the evening One Burst Grand Eruption. Rift was erupting as I arrived. It appears there was a Turban Delay in progress then, based on the next Turban eruption being without overflow and having both short interval and duration. The delay was for three Turban intervals, and Rift quit during Grand's eruption.

August 06, 2020

Observations for 2020 August 05

West Triplet was in eruption as we arrived at the Grand Group. It lasted only about five more minutes. Then it was an hour and a half of short Turban eruptions and intervals. That ended with what seemed like, at first, just another Turban eruption. But this one built in strength, and with the moonlight, it appeared that the steam over Grand was getting stronger.

Finally, after 2m12s, Grand began erupting. The first burst was short, followed by a short second burst. The breeze made it easy to see the entire water column in the moonlight. With a duration of less than ten minutes, we knew that the odds of a third burst were poor, but possible. What we didn't expect was for Vent & Turban to quit.

Up for the next Grand eruption with the sun well above the trees, and it already starting to get warm. This One Burst Eruption at least lasted just over ten minutes. At around 8-1/2 minutes, Grand went into full Big Sawmill mode. At one point, around the nine minutes mark, there were distinct bursts maybe four meters high for a period of about ten seconds. But it could never find a way to quit. The activity picked up a little before it all quit.

It had been well over 20 hours since the last time Artemisia erupted. So went on down there since there wasn't much else to do. After about two hour wait, finally got the thumps signalling the start. Pretty standard eruption, although the steam plume never overwhelmed the observation deck like the last time.

Looks like Beehive has found the ability to erupt daily again. Got the Indicator call, went over to Geyser Hill to see it, and made the mistake of not staying put but instead trying to run through the rain. At least a nice warm day, and dried out while waiting for Grand next.

Saw a big burst out of Depression as I was tying up my bike at Castle. Over at Grand, only had to wait one Turban interval for the One Burst Eruption. Afterwards, watched Slurp erupting and actually putting out a trickle of water. A major eruption.

For the sunset One Burst Grand Eruption, the sun disappeared behind a thin bank of clouds just as the waves on the pool started getting big.

August 05, 2020

Observations for 2020 August 04

It was mostly a Grand day. It started with a moonlight One Burst Eruption just after midnight. There was a hint of moonbows in the steam, which obscured the start.

The morning One Burst Grand eruption could've been a bit better. The sun was just starting to illumintate the tops of the jets. With a duration of just over 9 minutes, a second burst would have looke quite nice.

Later, just before noon, I walked up on the start of Rift. The water had yet to reach the boardwalk. After another One Burst Grand eruption, Rift was still active. Grand erupted on a Turban Delay, with some booping around four minutes before the actual start. The start itself was slow, with building boiling before a nice bubble start.

I did get to see an eruption of Bulger's Hole. Bulger had been having its frequent minors, and I caught one just after the Grand Eruption. Ten minutes later, it had a major eruption. Four minutes into that, the Hold erupted to 2 to 3 meters for about 30 seconds, then quickly draining.

Also saw the start of Grotto Fountain. The top of the water column was easily over the tops of the trees in front of it for well over a minute.

Checked out Oblong, but no more eruptions since the one in the dark. The runoff channel from Solstice looked even drier, at least at a distance, which re-inforced the idea that it had quit shortly before my observation the other day.

The final Grand of the day occurred before sunset. There was a delay this time, too. The standard delay where the following Turban eruption is short, with no preceding runoff. This time there was finally a second burst. What made that a little more interesting was the the pause was long, over a minute, and there were several large boop-like boils before the burst actually started.

Observations for 2020 August 03

Headed up to Norris at dawn with the expectation that there wouldn't be much reason to stay past noon. When we arrived at 06:20, what we saw did nothing to persuaded me otherwise. New Crater/Steamboat was pretty quiet. Down at the bridge there was a steady trickle of water, augmented by widely spaced surges from South Vent.

Over the next 3-1/2 hours we never saw anything that looked promising. The weather deteriorated, with a thick gray cloud cover, and no warmth. As for the geyser, there was no vertical activity from North Vent, nothing sustained and definitely nothing approaching any sort of notable surge. The only thing I saw that was moderately encouraging was that it appeared that occasionally the play was nice and wide, and wasn't being killed by South Vent. Was considering moving my deadline from noon to 10:00.

So it was a complete surprise where we got a really nice burst out of North Vent at 09:56. One that kept building, turning into a surge as South Vent joined in. In a matter of seconds, it was obvious that an eruption had started.

Everyone was completely unprepared. It took me 40 seconds to dig out my phone/camera, attach the handle and start recording. I did have the presence of mind to almost immediately run down to the runoff and see what it looked like. I captured the appearance of the North Vent runoff channel filling, impressive how calm that started, only to be a raging stream a few seconds later.

At that point, returned to my seat where I at least covered the packpack in its raincoat. At first it looked like we could get some chokes, as slight the wind was toward the north. The North Vent was brownish and not steady, while the South was taller and continuous.

Then the wind shifted, toward the platform. I had to abandon the area to get out of the rain and into my raingear before becoming soaked. But that also meant that nothing was being washed into the North Vent. It became clear and clean for the rest of the time we were there. The wind kept slowing shifting from down to the bridge to the upper platform. No spot was safe.

After returning to the Upper Basin, went out for Grand. It first had what appeared to be a Turban Delay, which the long duration and subsequent lack of overflow before the next eruption tended to confirm. After two intervals, there was a second delay. This time Grand did erupt on the next opportunity. It was less than 17 minutes later, and overflow from Grand was just starting. Grand filled over the next minute until it finally had a series of increasingly larger boils. One Burst, as usual.

Last night, while waiting for Grand, I thought there was a period of time where the steam from Oblong had increased, and it might be trying to erupt. As it turned out, it did erupt a few hours later. There was a second one while we were still at Norris. So after Grand, when down to check things out. I couldn't see or smell any evidence, despite knowing there had been eruptions.

Also while down there, checked out the Giant platform. Grotto had had a long marathon yesterday lasting until around dawn today. It looked like Bijou started erupting while we were waiting for Grand. The platform was totally dry, which indicates that despite the changes going on around it, Giant isn't ready, yet, for a hot period.

August 03, 2020

Observations for 2020 August 02

Once again went out for activity at Mugwump and friends. The sequence of events there seemed fairly standard-- Mugwump was erupting every sixteen minutes or so. About five minutes later Three Crater would start having splashes, some up to two meters high. These continued into the next Mugwump eruption, when it would stop. In addition, Myriad Group #1 was active. This would start having strong convection at the time Three Crater would start, and last about two minutes. On one occasion, it had a couple of bursts to about 1/2 meter.

The water level in Sawmill's pool is as high as I've seen it since it was active. I thought I'd post a photo of it showing that. Note the small catchment in the foreground.

Arrived at Grand for a Turban Delay and a West Triplet eruption. The latter wasn't long enough to trigger Rift, and the Delay was for only two Turban intervals. It was a One Burst Grand eruption, not too exciting, but nice sunny conditions.

Got to see Artemisia erupt for the year. Was hot and dry and sunny, so perfect conditions, except the breeze was up the slope, so had to constantly keep shifting position. There was also an Atomizer minor eruption, little more than heavy splashiing, at the start, but didn't stick around for any more activity there.

Was one of the hotest days I've experience here in years. Supposedly the weather station recorded 86F. So was a pleasant surprise for the afternoon One Burst Grand to require only a short wait. During most of the eruption, there was a full rainbow from Vent all the way to Rift. And for the first time in quite a while, there was a short pause before Vent & Turban restarted. Once again, there was a short, about six minute duration West Triplet eruption shortly after.

Later took advantage of the full moon to experience Grand. It cooperated in erupting not only before midnight, but had two bursts. The moon was too high for any rainbows.

August 02, 2020

Observations for 2020 August 01

First up was a visit to Mugwump and friends. Spent about three-fourths of an hour there, seeing three eruptions. The last was much larger than the first two, in that only the last one put water down the runoff between the pool and the roadway.

Before each eruption, Three Crater started up. A number of the bursts seemed larger than in the previous visit. The activity there stopped with the Mugwump eruption, only to start back up again about six to eight minutes later.

When saw the activity the previous visit, in late June, there was one time when I waited in the evening when there was no breeze but still warm. The pool was dead quiet at times, and it was possible to see convection and upwelling from and area in front of Mugwump's vent. Today, before the last, large eruption I saw, this area boiled heavily and had several bursts to about 25cm. This activity was seen about the time Three Crater started and lasted for a couple of minutes. It was seen again just before the Mugwump eruption.

Over that Grand, all the sputs were quiet prior to the One Burst Eruption. There were consecutive Turban delays. The Grand pool filled slowly during the second delay. There was never a time it looked really good, then dropped. The progression was just extremely slow. So much, that Grand started having heavy boils and even boops nearly two minutes before the eruption finally started.

Down basin, Solstice Geyser is quiet. From what I could tell, the runoff channel was dry and the slime mat was drying out, implying it's been that way for several days. During the days prior to this visit, I'd seen reports of it being both active and quiet, so will be interesting to see if it is becoming intermittent, with long durations and intervals.

At Giant there was no evidence of change or increase in activity. The platform was nearly dry, with just the usual puddle next to Giant's cone that could have been rainwater. At Oblong, I did walk up to it slightly below overflow. That restarted a few minutes later, obvious from the steam coming from the catch basins near the vent.

Conditions in the morning were clear, sunny and almost too hot. That changed by the time it was time to head out to Grand. There had been distant thunder for about an hour before that, and it was mostly cloudy with occasional sprinkles as I headed out. After a couple of Turban intervals I finally had to put on the rain gear.

While the rain stopped by the time the eruption started, the wind shifted and it got more humid. That meant that when Grand started, the northern benches got wet and there was so much steam it was difficult to see much of the eruption. So it was a bit of a surprise when finally, after a minute of waiting, there was the first surge of the start of the second burst. And thanks to that amount of time and the wind direction, it was possible to see the full water column.

I made it as far as the bridge before I had to wait at Castle for a lull in the rain to bicycle back to my cabin.

Today I noticed that the Firehole River is as low as I ever see it, with the ledge at the Sawmill runoff channel completely exposed. But I also noticed some fresh, clean gravel has been washed below it, creating a debris fan. I expect that when Sawmill reactivates, it will create a huge delta, but what caused this small one? Closer examination shows that the area around "Snake Eyes" & SG-#8 is exceptionally clear of debris, as well as the runoff channel, as the photos here show. I suspect there was an eruption there. I didn't notice this when I left in early July.

August 01, 2020

Observations for 2020 July 31

The One Burst Grand for our return was not particularly auspicious. Arrived well after sunset, but that glow, with the moon meant it was still light. Ended up waiting almost two hours for an almost 7-1/2 hour interval. The Turban activity was dull and normal, and if there was a delay, it was well before we arrived. The moon was visible when we arrived, but clouds moved in from the north so that there wasn't even a glow by the time of the eruption.

The only item of note was the frequent activity among the sputs, probably Sput D. Loud (for nighttime) and frequent, and what exactly is going on there will have to wait for daylight.

Observations for 2020 July 06

Out at dawn to sit in the fog. Grand erupted on the Delay, and even had a second burst. The wind picked up enough to push the fog away once the eruption started.

A few hours later was headed out to Castle and then Grand when got the call that Beehive's Indicator was erupting. So instead went over to Geyser Hill to catch Beehive up close. Considering the one to three day intervals and the number of no-Indicator eruptions, have seen a few from Geyser Hill. This one drenched the walkway well beyond Anemone.

Castle was erupting as we finally got down that way, and the One Burst Grand interval was less than six hours despite a Delay.

From there it was time for Daisy, and arrive about two minutes before the eruption. I didn't see anything from Splendid during that brief time. The Daisy duration was longer, 3-1/2 minutes this time.

From there caught an Atomizer major eruption, then returned to Daisy again. This time was around long enough to confirm that Splendid was doing nothing prior to Daisy's eruption. Worse, the duration of the eruption was just over three minutes.

While waiting for Daisy, a coyote wandered past between Splendid and the trees, heading south. After Daisy's eruption, we just got on the main bike trail when several coyotes off to the southwest started yipping and barking. Usually hear them from that area in the evening or dark, not in the middle of the day.

Caught the fourth Grand eruption of the day, and this time not only did it not have a Delay (I was there fairly early and saw several intervals), but there was a second burst. It was a short eruption, a bit over ten minutes long, but Grand made only a feeble attempt to refill, then Vent and Turban quit.

July 06, 2020

Observations for 2020 July 05

Heading out to Grand when I noticed that Crystal Spring was in overflow and Belgian was full. I've yet to see any pattern in their levels.

There were never really any good waves. But suddenly Grand had a couple of small boops, about 1/2 meter high. Almost immediately, the pool began to drop. It was four minutes before Turban started erupting, and by that time, the interval was well over 25 minutes for a Delay.

The duration of the Turban eruption wasn't out of the ordinary, lasting a bit over five minutes, so at least a delay of two Turban intervals was expected. It was a surprise then to see a full Grand Pool and waves at the fifteen minute mark. There wasn't any overflow that I could see. A minute later, with overflow just starting to be vislble due to its steam, Turban started almost explosively. It took Grand only about 30 seconds to join in.

Eight and a half minutes in, it looked like Grand had paused, only to restart and go into a Bit Sawmill mode for another minute. Vent and Turban, at least, didn't quit.

There was another West Triplet eruption after Grand, this one only lasting 6 minutes. Belgian and Crystal had dropped a bit, the latter below overflow, and Slurp was noisily erupting at depth.

It appears that Aurum may be shifting into summer mode. Spent a little time around it well after the six hour mark. I did get to see the pool just north of Doublet erupt. When I arrived, it was withing the lower rim, but splashing a few centimeters high. The wash zone around it was dry. At 16:34, I saw it erupting to about 1 meter, and the wash zone was filled. That was the end of the eruption. I don't know the name or number, or anything else about what it does.

Saw Turban erupting as I tied down my bike. 35 minutes later I saw the next Turban eruption. For about ten minutes, it looked good, but there were never any waves. Fortunately, the next Turban eruption had no overflow, and Grand erupted on the second Turban fill. This was another two burst eruption, with excellent lighting. West Triplet started during the second burst.

It appears the way to keep Rift from erupting is to want to video record the start of an eruption. I've now seen a number of complete West Triplet eruptions, and never has Rift shown any inclination to start. Percolator and Sput D tend to start about ten minutes into West Triplet's eruption, then they quit shortly after West Triplet ends. One variation was today's later eruption where Sput D stopped for about five minutes.

It being full moon, went out for a few eruptions with that in mind. Unfortunately, Castle erupted before moonrise, and the One Burst Grand didn't seem to have the same moonbows of the night before. Did finally get the Rift start. It didn't seem to matter as Grand erupted about 15 minutes later, but wasn't able to record it.

July 05, 2020

Observations for 2020 July 04

Did another check on Daisy. This time there wasn't any boiling in Splendid prior to Daisy's eruption, but there was water in the orange lobe and it dropped as expected. The boiling afterwards didn't seem quite as strong, but was from both vents, and I didn't stay around for long.

Grand was cooperative in the morning. I think I arrived for a Turban Delay, as the first Turban duration was well over six minutes, and for the next one Grand's pool didn't have much, if any, overflow. The real cooperation was that there were two bursts, and it was fairly obvious that the pool was not going to drain before the second burst started. West Triplet started after, but there was no eruption of Rift.

Came out early for the next Grand opportunity, arriving with West Triplet and the sputs all in action. Again, there wasn't an eruption of Rift. This time there definitely was a Turban Delay, as the interval was over 36 minutes and Grand even had a couple of small boops.

Two Turban intervals later, we got another Grand eruption were there wasn't much doubt there was going to be a second burst, but this time , after about 45 seconds, Grand went into Big Sawmill mode. At that point it felt like it was trying to stop, and just couldn't. This lasted for at least 20 to 30 seconds, when finally the activity picked up a little bit. This continued on for a burst lasting nearly three minutes.

Then finally got the opportunity to see Grand by moonlight. There were occasional clouds covering the moon for a few moments, but nothing threatening. It was One Burst Grand, but the moonbows were some of the best I've seen. From West Triplet, for moments there was visible a full arc extending to the left and over the steam from the Daisy Group. At times, it seemed like the stronger parts, in Grand's water column, had a hint of color in it. Best of all, the dozen or so people out there didn't feel the need to provide their own illumination.

July 04, 2020

Observations for 2020 July 03

Arrived at Norris at our usual time. It was three hours before there was any activity worthy of note. It was a nice, strong surge with the usual little bit of vertical to the right of the North Vent. Following that, about every half hour to hour there was a similar event, but in most cases there wasn't any followup. The next to last event was at 13:33.

The following event was about 45 minutes later. This one looked different from the beginning. It was stronger, thicker, and the vertical surging was definite and pronounced. Within moments, it built into the eruption start, at 14:15. I somehow managed to capture this on video, despite my efforts to screw it up. I'll post the video the middle of next week.

I waited too long to get a height measurement. By the time I got back to the bench, all I got was 50%, which works out to about 65 meters or about 210 feet. Still taller than any other geyser but Giant, but well below what it had been a few moments earlier. This was probably because of the wind direction causing much of the water to flow back into the North Vent. The water was already brown after about five minutes, and threatening to have a full choke. Unfortunately, that never happened. Most of the runoff was behind and toward Echinus. There were several new runoff channels forming over there, while nothing was going in west of the North Vent's runoff channel. That channel was practically dry for most of the eruption we saw.

Thanks to the wind direction, it was easy to see the base of the water columns and the vents for most of the eruption. At times it was obvious that there were several areas of forced steam around and in front of the South Vent. In addition, it was easily apparent that there is some sort of third vent to the right of the North Vent. The video I took shows this clearly.

Finally left the area after a couple of hours. The steam was mostly steady, but some chugging could be seen and heard when the wind shifted more toward the north.

In the Upper Basin, attempted to go out for a post-sunset, early moonlit eruption of Grand. But a thunderstorm moved in and we had no desire to get soaked by it, so headed in before the One Burst Grand eruption could happen.

July 03, 2020

Observations for 2020 July 02

Started the day out by waiting for Daisy to erupt. Splendid was quiet when I arrived, but it was pushing water out into the orange northeast lobe. As Daisy activity increased, the water in Splendid dropped so that the water was no longer going into that orange area. Then, about a minute before Daisy, Splendid's Main Vent started to boil up to about 1/2 meter. This is the first time I've seen such activity in a long time. It quit as Daisy started, which was expected.

The Daisy eruption as again short, this time 3m17s. But a few minutes after the end, Splendid started having boils from both the Main Vent and the Side Boiler. This activity continued for about 20 minutes, and I left a few minutes later. I stopped by about an hour after Daisy, and did notice a small boil from the Main Vent. So there's definitely a small pickup in the activity from Splendid. Will have to see if there's any progression over the next few months.

At Grand, West Triplet was erupting as I arrived. After it ended there was a series of indistinguished Turban eruptions, which lead to a delay. Finally, three more Turban intervals later, Grand had its One Burst Eruption. West Triplet started almost immediately. I expected this eruption to trigger Rift, but was disappointed.

When I came out for the next Grand eruption, I was surprised to see Percolator and Sput D erupting with West Triplet completely drained and dry, and Rift quiet too. About ten minutes later West Triplet started from deep down in the vent. This eruption finally resulted in an eruption of Rift. It was right after the end of West Triplet when Grand erupted. This time we got a second burst with low sunlight and clear skies behind the water column.

July 02, 2020

Observations for 2020 July 01

The first Grand eruption of the day was distinguished by being a short One Burst Eruption that had a long period of the pool pulsating before draining. From there it made sense to go to Geyser Hill, as it had been nearly three days since the last Beehive eruption, and was in the latter half of the Aurum interval.

Aurum seemed not a vigorous as at other times, but still looked promising. So was in the wrong location when Beehive suddenly began. Because of the strong, shifting wind, over by Sponge we got soaked several times. Shortly after than we got the Aurum eruption with an interval just under five hours, so a bit longer.

The next wait at Grand was long, for no apparent reason. No delay, no West Triplet, not even heavy overflows. Just a couple of hours of weak Turban eruptions until it was well out of the NPS prediction window and the crowd started to disperse. But once again, Grand did reward us with with a seconds burst, and despite the wind, the sunlight made for a nice view.

It's interesting in how some observers are intent on recording every spit of every little feature and sput of a group, then fail to report the most interesting activity. A case in point is how some are reporting all the little sputs around Daisy, yet then fail to note the duration of the Daisy eruption itself. That's a number that changes over the years, and seems to be related to the activity (or lack of activity) of Splendid. Back when Splendid was active, the durations were about 30 seconds longer, and if the current value were to start showing a change back to that, it would be good to know. Besides, it's not that hard to calculate.

July 01, 2020

Observations for 2020 June 30

With the weather forcecast for damp and cold, it seemed like a good day to be elsewhere. Did get out for a One Burst Grand in the morning. Expected to wait a while, with all the recent longer intervals, but this time it cooperated and had an interval less five and a half hours. So was able to hit the road earlier than expected.

June 30, 2020

Observations for 2020 June 29

Checked out Oblong, and if I hadn't known there was a report of activity the day before, I wouldn't have been able to determine that from what it looked like. Did not look like the black slime mats were torn up, and because of the wind, not possible to determine if there was any smell of cooked vegetation. The crater was back to full and overflowing.

Right after that was another undistinguished One Burst Grand eruption. The poor weather was dry enough that I did go out for the next One Burst Grand. It was nice to have a short interval although the threatened rain never came.

June 29, 2020

Observations for 2020 June 28

Yesterday just south of the entrance to the Firehole Canyon Drive I encountered two rabbits that were feeling suicidal. At least they ran out from nowhere right in front of my vehicle. I don't think I hit either one. This morning on the way to Norris there was another one at the same location, and I definitely heard a thump this time. The strange thing is that I can't remember ever seeing rabbits anywhere in the Park.

And it's a pretty miserable day when the highlight is kiling a rabbit before dawn. But other than a strong minor a few hours after we arrived, New Crater/ Steamboat looked a bit better than yesterday, but not my much. The rain started around noon, and lasted until we left around 19:00. The platforms were full by noon, but not crowded. It was pretty calm there because many of the gazers who need to socialize (sometimes at high volume) have decided to stay home this year. The most crowded place was at the bridge over the runoff channel, where the line of people and chairs along the railing(s) forced vistors to run a gauntlet to get through.

Because of the weather and lateness of our return, I didn't get a chance to confirm the report of an Oblong eruption today.

June 28, 2020

Observations for 2020 June 27

It wasn't really necessary, as all the indications were that it was too soon, but went up to Norris anyhow. The first few hours of activity by New Crater/Steamboat were so poor that we were considering leaving around noon. But as the day progressed, the activity did improve enough to suck us in until early evening. By then it was obvious that the progression had stopped, and no reason to stick around.

Did see an eruption of Vixen. One that lasted, and lasted and lasted... I gave up after 25 minutes, and it turns out the duration was closer to 45. This after having been fairly regular with about 1/2 hour intervals and durations from 10 to 15 minutes.

Arrived back in the Upper Basin to discover that Grand was having an interval well over 7h20m. So went on out, expecting to see the start while still on the bike. Instead got out there for a full Turban eruption interval.

The pool was nice and full and having waves the next time Turban started. Instead of the expected "vigorous" Turban, it actually had no bursts for several seconds before restarting. It took Grand about 75 seconds to finally start.

Grand also rewarded those who had waited all that time. The first burst lasted 9m19s, which is right on the edge of having one or two bursts. It was easy to see that the pool had water and wasn't draining, so like the other evening, we got another second burst after a long wait.

June 27, 2020

Observations for 2020 June 26

Thought I was going out for a twelve hour double interval at Grand, and it turned out instead I was showing up shortly after first overflow. That was because, following the previous evening's long interval there was another one overnight. Then we had a three Turban interval delay before the One Burst Grand eruption. The delay did insure that it was nice and warm and not steamy.

Was thinking of then heading to Artemisia, but seeing the steam cloud over the ridge just before Grand started meant there was no longer a reason to do that. But a notification that Beehive's Indicator had started was welcome. Considering that right now Beehive's intervals range from one to four days, any opportunity to see it up close will be taken. This was right after an Old Faithful eruption, so there were quite a few people there despite no one there to encourage them to stick around.

Then checked out Aurum, which it turns out had erupted during Grand's eruption, but we did get soaked by an eruption of Lion right after Beehive.

Later that afternoon, got a radio call from Lynn Stephens announcing a window for an Atomizer major eruption. Since I rarely see that geyser, and there was nothing much else to do, it was a good time to head down there. Since it was warm and Artemisia had already erupted, it was not obscured by steam.

Daisy has been having intervals under two hours, so worth checking to see if there are any other changes in the area. Was able to predict a double interval and be there for an eruption that lasted only 3m13s, which seems even shorter than previous years. Before the Daisy eruption, Splendid did nothing other than a blip over the Side Boiler just as Daisy started. Afterwards, in Splendid the Side Boiler and the Main Vent alternated having heavy boils, some almost a meter high. That seems stronger than prior years. I left after about ten minutes and they were still active.

In the afternoon Grand had another two Turban interval delay before the One Burst Grand eruption. There was a short, 19minute long West Triplet eruption at about the time of the delay. The only other thing of note was that when I arrived, Slurp was again in eruption. No overflow from it or from Crystal, but quite noisy and splashy.

Finally, just to show how dull and boring the Upper Basin has become, I went to Great Fountain for a late evening eruption. Before sunset, so the better view in the warm air was from the benches. It was a long pause, nearly nine minutes, but the first burst had some really nice tall plumes and some nice explosions at the start.

June 26, 2020

Observations for 2020 June 25

It was a dark and stormy day. Got to experience several rainstorms and a hailstorm. Because of that, didn't spend much time out and about. Did get to see couple of One Burst Grand eruptions. By evening, it was dry enough so no excuse not to head out to Grand again.

There, it was something other than of the usual one or two Turban eruptions, delay and then the One Burst Grand. Arrived to find Slurp in an eruption, without Crystal in overflow drowning it. The rest of the Sawmill Group didn't look like it was in a deep drain, so this was a little different from years past.

Got an eruption of West Triplet that didn't lead to a Rift eruption, but during that time had one of those short, vigorous Turban eruptions that act much like a delay. The following eruption was quick, with no overflow, so I was fairly confident that would get the Grand eruption next, shortly after the West Triplet eruption would be ending.

That didn't happen. Instead, got another pseudo-type delay, this time the interval was about 24 minutes. So it was wait two more Turban intervals. By this time the chances for a sunset lit eruption were over, with the sun behind a thick bank of clouds. Also by this time the wind died down completely, with what little movement there was seeming to make the steam follow me no matter where I moved.

I did finally manage to get down by the Vent sign where I could at least see Turban, when out of no where Grand had a 4 meter high burst starting the eruption. Despite the rain there, I did manage to get the start of other activity. The eruption was shrouded in its own fog most of the time. But it was a pleasant surprise when the activity quit at just over nine minutes, and we finally got a second burst instead of the usual short One Burst Grand. This time we could see the water column above the steam, and there was just enough lighting to see some detail.

June 25, 2020

Observations for 2020 June 24

Discovered the hard way that the bike trail to Fairy Falls beyond the Grand Prismatic overlook is closed because of bear activity. Gotta remember to chec the signboards at the trailheads. (In this case, the incident was two days ago, and didn't get publicity until today.) So returned and did a loop of the Lower Basin to find that pretty much everthing of interest was in the middle of its interval. Did finally stop by and see a full Flood eruption, but the attempt to video record the eruption was not successful due to operator error.

Spend a few hours at Three Sisters to learn more about how things work there. Got to see a major Mugwump eruption (one lasting 25 seconds with multiple bursts) and what was probably the last minor (one having a single large burst, lasting about 10 seconds). Three Crater also seems to have multiple modes, from a single large boop to multiple distinct bursts over a period of five or more minutes, but I haven't quite figured it all out.

Did see three more One Burst Grand Eruptions. Two of them came on delays. The last one of the day went into Big Sawmill mode for the last few minutes, with multiple false pauses.

A final indignity was to wait for a West Triplet to finish. It lasted nearly 35 minutes, but Rift didn't start and wasn't even steaming. So I left. Looking back from the walk up to Crested, I could see the steam from an eruption of Rift starting.

June 24, 2020

Observations for 2020 June 23

Rift started about the time we were tying up the bikes at Castle. Then we got a Turban delay. Grand overflowed heavily for about 20 seconds, and there were even some boops before the start. Then Turban took well over a minute to start, and Vent was 3m06s. It was the first One Burst Grand of this visit.

Afterwards, with Rift still erupting, Sput D and Percolator started up. Sput D appears to be much larger than last year's activity, and stronger. It stopped once, and so did Percolator, for about 30 seconds. That's something different that need to be confirmed. After the restart, I noticed a wet frying pan in the gravel at the site of Sputnik. It didn't last long, and I didn't stay around much longer.

After seeing a number of eruptions on the webcam, it was time to try and see Mugwump in person. So it was nice that it erupted within a couple of minutes of our arrival. The eruption lasted 25 seconds, and consisted of a number of large bursts that put out waves into the wash zone to the northwest of the vent. It was also preceeded by a burst from Three Crater, but was there so short a period of time that am not sure it was an isolated burst, or the last of a series.

Waited for another eruption, and started to piece together what to look for. After about ten minutes Three Crater started erupting. This consisted of a long series of distinct bursts about 5 to 10 seconds apart, ranging in height from a meter to maybe 2 or 3 meters high at times. There's a small spot of convection near the edge of the pool closest to the road. The activity from Three Crater made the surface of the pool rough, but it appeared that the convection died down while Three Crater was active. After Three Crater finally stopped, the activity inthat area slowly built up. Eventually there was a second area of convection well behind it in the pool. When that activity picks up, that's when it's time to start the video recording. This eruption looked like the previous, and even put a stream of water into some runoff channels.

The final eruption of Mugwump was different. It came on a shorter interval, lasted maybe ten seconds, didn't reach much height, and the water never made it into the wash zone. Others have reported only seeing these small eruptions, none of the bigger ones. So there appear to be some modes in the behavior which futher study will be needed to understand.

Observations for 2020 June 04

Stopped at West Thumb on the way home. In terms of thermal activity, nothing to report. Lots of craters with opaque hot water at the bottom, more deep holes discharging boiling water, and nothing even splashing or sputtering or even sizzling.

What was noteworthy were the number of elk. Saw at least five or six hanging around in the thermal area and parking lot, including a mother and fawn right next to the boardwalk blocking southern access to the lakeshore, requiring a lot of backtracking. Then I heard one bugle off beyond the parking lot.

June 04, 2020

Observations for 2020 June 03

Was thinking about going out to Grand in the night, but while the moon was bright, it looked like the clouds were coming. Decided to not go out. I woke up again about the time of the eruption, and that proved correct. And the interval was closer to seven hours, which would have made for a long wait.

It was a short wait at Grand. The eruption was perhaps the best of the trip, with what little wind there was pushing the steam up the hillside, so all the vents were visible and the water column and jets were nicely backlit. In addition, there was a second burst.

I couldn't go up on the south side of Daisy as there were five bison bedded down in the area near the trail between Bank Geyser and Bonita Pool. After the Daisy eruption, I watch Splendid for a while. After about four minutes from the end of Daisy, the Side Boiler finally started small. With twenty seconds or so, the activity shifed to Main Vent and stayed there. After a few minutes there were even a few strong surges to about a meter.

The best Grand eruption of the trip had to be followed by the worst. It was still partly sunny when we got out there, but we could see the clouds building to the west and north. It got progressively cooler and windier until we could hear some thunder. By that time Beehive's Indicator started. By the time Beehive erupted, Turban had some sort of delay eruption. It was hard to tell through the steam, but it was probably a Vent Overflow delay. Turban started strong and vigorous, but lasted less than 3-1/2 minutes. Grand's pool level dropped more than normal.

By then, the rain started, and the wind really picked up. It was two Turban intervals later that Grand finally did erupt. A One Burst Grand lasting 8m53s. It was around that time that the wind died down and the rain slowed to a shower.

June 03, 2020

Observations for 2020 June 02

With Grand having an over eight hour interval overnight, there was nothing to do in the morning. So visited the Lower Basin again. A Fumarole was back to being a fumarole, and the Fountain Paint Pots had thickened up enough to make some nice mud cones. There was still a slightly bluish pool over some of the white mud area in the center.

Great Fountain overflowed sometime during the half hour we went to the Paint Pots, so there wasn't much of a wait. And the "Big Boil" lead directly into a decent eruption. I tarped my truck just in case, so there wasn't any target for a superburst.

Back in the Upper Basin we had a short wait for the next One Burst Grand Eruption. There was almost a delay, with a Turban eruption interval of 24m59s. But Grand erupted on the next Turban. During that eruption Castle started, and had another major. I haven't seen a minor this trip.

The Firehole River is still high, with water well over the step at the base of Sawmill's unused runoff channel.

The evening was pleasant, although a bit windy, and would have been a great sunset eruption of Grand. But instead we got Rift starting (with Belgian down about 1-2 cm) and a Turban Delay. Grand showed no desire to erupt until after the sun finally disappeared behind a thick cloudbank above the ridge. Then our D4 One Burst Grand eruption happened. Rift quit at about the same time as Grand, with a duration close to two hours.

During the Rift eruption Belgian had risen back to the rim, and at some point Slurp had also risen and was discharging water along with occasional spits. I'm pretty sure this was not Crystal Spring runoff, too.

June 02, 2020

Observations for 2020 June 01

Riding out in the morning I had to follow a coyote up the hill to Castle. I was headed out in the morning to enjoy what I expected would be the last quiet morning of the spring. The roads in from Montana were opening at 10:00, and figured there'd a fair amount of pent up demand to visit the park, especially today.

So first went to see an eruption of Daisy. Over by Pyramid were 8 bison bedded down. It was a nice, normal Daisy. I didn't stick around to watch Splendid as usual, because I wanted to get over to Castle to catch the next eruption after the one we saw the previous night. I saw Castle start just as I got onto the main bike trail. There was one long pause about four minutes later, and then continuous activity leading into the steam phase.

From there I saw that Rift and West Triplet were erupting. When I arrived in the area, West Triplet had quit, and Belgian looked full and normal. Bulger was having a series of minors. While waiting on Grand, did see a huge eruption of Rocket, well above the trees. Also saw Percolator for a while.

The One Burst Grand came after a Turban delay. Rift continued to erupt during the eruption. Percolator had quit, but Sput D was active. Then Bulger finally had a major eruption. It only lasted a bit over six minutes, but the Hole showed water twice-- at about three and five minutes. The first time there was even a splash or two but the water level never rose higher than about 40cm below the surface.

Went down basin to confirm that there was no reason to pay close interest to either Fan & Mortar, or to Giant. It was near time for Riverside, so we were there when we heard the call for Beehive's Indicator via the webcam. It was a nice view from across the river.

Later it was back out to Grand. Not long to wait for another One Burst Eruption. The crowd wasn't much bigger than what we'd been seeing for the past week. The mass of people I'd expected to rush in from Montana appears to not have materialized.

The webcam people are starting to annoy me as an observer actually in the basin. They seem to be unable to have one report of activity, but must have at least three for every geyser. So many that I've had my "in the basin" reports superceded. They really need to figure out how to arbitrate their little competitions for "Level 5 Geyser Guru" and make one posting.

The other problem is that some people insist on posting useless observations like Pump Geyser. The excuse cited is that "it's to show that the geyser is active." So I decided that it's not just pump, but other features like Tortoise Shell, Comet, Spasmodic and Witches Cauldron that deserve the same treatment. Better yet, those camera watchers should actually spend some time on Geyser Hill and actually watch Pump for a while to learn what it normally does and what sort of activity is worthy of being reported. (They could at the same time see about getting 100 consecutive Sponge eruptions.)

June 01, 2020

Observations for 2020 May 31

Day started out warm and breezy. Arrived to see West Triplet and Percolator erupting, but no Rift to follow. The Grand eruption about two hours later did have a second burst, and was even so short that vent & Turban didn't quit. Belgian pool was lower when I left than when I arrived, which was interesting.

Later went over to Geyser Hill and caught Beehive eruption. By then the wind had gotten stronger, and of course, as we waited, it shifted toward our position over by Plume. As it turned out, we were right on the edge of the wet zone, and that little corner remainded dry.

Over at Grand Rift was erupting. Belgian was down even more and Slurp was making noisy, sloppering noises but not putting out any water. Bulger was having a series of minors. During the One Burst Grand eruption Rift quit, and Belgian had risen back close to its rim.

Made a quick trip out to Castle to catch an early evening eruption that I saw mostly by myself. It tried to stop once around the four minute mark, but otherwise contined a nice series of mostly major eruptions. (At least what I've seen.)

As the sun set the wind died down, so the wait for the next One Burst Grand wasn't unpleasant. But first we had to have Turban delay, which made sure that it was completely dark. With the quarter moon giving just enough light to see the eruption, that delay may have made the One Burst Eruption more interesting.

May 31, 2020

Observations for 2020 May 30

A fourth day like the third, although this time there were a couple of moments when it appears that there was going to be an eruption. But in the end, it was another day wasted.

Did get to see a bear on the drive up. It was walking up the road toward Gibbon Falls. I saw this dark lump there, and wondered if it was a small bison. Then it started running and was obviously not a bison. It kept running as we approached, then jumped over the rock wall and was running up the fenced in path. Last we saw of it, it was still running on that walkway.

May 30, 2020

Observations for 2020 May 29

A third day of things looking better at Norris, but not looking good enough. At 13:28 there was an unexpected push that sure looked like New Crater/Steamboat was starting, but after about 30 seconds, it died down. Nothing much the rest of the day other than a couple of vertical episoded early and a couple near the time we were leaving.

The bison were really out in force. Near Tuff Cliff was a herd of about a dozen cows, each it seemed with a calf. Several other places along the way we had to slow down or stop for bison on or near the road.

May 29, 2020

Observations for 2020 May 28

A second day at Norris pretty much like the first. The activity was a bit stronger, especially from the South vent where there were numerous bursts to 10meters putting out lots of water. But until 1903, nothing much out of the North vent. Then there was the usual increase in activity just as we were leaving. This time there was a sustained minor with some North vent vertical. Then nothing much for 20 minutes.

The drive back was amusing. Between Madison Jct and Biscuit Basin, encounter a bison in the exact center of the road. Then beyond Midway were flashing lights and someone talking to a ranger. Around the curve were more flashing lights, and a semi-tractor trailer. Then just before Biscuit, just as the sun was about to set, were two bicyclists headed north. And it looks the the one lane restriction on the overpass at Old Faithful is about to start.

May 28, 2020

Observations for 2020 May 27

A day spent at Norris, where nothing much happened. Steamboat/New Crater looked pretty much the same when we left at 19:20 as when we arrived at 05:50. Seemed like good water coming from the South vent, but North vent was initiating most of the activity, and only once, in the middle of the day, did we see anything approaching vertical.

May 27, 2020

Observations for 2020 May 26

Had decided to not come out for the pre-dawn Grand eruption, so it was a bit of a surprise to find it erupting shortly ater 08:00. That meant that most likely that there were two long intervals overnight. It also meant that I wouldn't be getting out until later.

Did go out after noon, and watched a series of similar Turban eruption intervals. Unlike previous days, there was no hint of any sort of delay. So it was nice to also be rewarded with a second burst, although the eruption was just under ten minutes long and Vent & Turban did quit.

Went on over to Geyser Hill again, to check on Beehive but not stay. It was having minor splashes, but nothing that looked imminent. Over by Aurum and watched and felt a episode of thumping by Doublet Pool. With few people on the boardwalks, it was easy to feel them. Then Aurum erupted just as I was getting ready to leave. Better behaved than in my previous attempt at seeing an eruption.

The day ended with a report of Beehive's Indicator starting. It was a long one, giving us plenty of time to get within view. And again, the area was far quieter than usual. Old Faithful had just erupted, so there were a few families wandering about

May 26, 2020

Observations for 2020 May 25

The weather was finally clear and sunny. So went down basin to watch and wait for something. Ended up being Daisy, where it was the middle of the interval. Splendid was calm for the hour or so I waited there. I did see a couple of Pyramid eruptions, too. The duration of the Daisy eruption was only 3m10s, which seems to be continuing the trend of shorter durations. In years past it seemed like Daisy was regularly 3m40s.

After that, it was to Castle, since it was well over 13 hours since the major eruption last night. Only waited about five minutes for a start. It was strong the whole time, except for a series of pauses between four and six minutes.

Then it was over to Grand. Arrived to a full, steamy pool that slowly dropped. The Turban duration was well over six minutes, which makes me suspect we missed a Delay. That the next Turban interval had almost no overflow tends to confirm that.

Grand erupted on the next opportunity, with Turban taking almost a minute to join in. After yesterday, we couldn't be sure what would happen when Grand quit after 9-1/4 minutes, but through the steam we could see the water over the vent, and we were finally, on the tenth try, rewarded with a second burst. Of course that meant that Vent & Turban had to quit.

West Triplet was overflowing heavily by then, and I did catch weak eruption, with lots of thumps, that lasted five minutes. Then it was a Bulger major eruption, and by the time that finished, it was only a few minutes until Vent & Turban restarted.

So because of that, I ended up seeing Beehive start as I passed by Sawmill. I didn't notice any steam to the left as Beehive was climbing in height, so I'm almost certain there was no Indicator. What isn't know is was that really an interval pushing four days, or were there some missed nighttime eruptions? In any case, the days of multiple Beehive eruptions in a day seem to gone for a while.

It was pointed out to us yesterday by Rebecca Roland that one of the vents at Spasmodic had a strange purple color to it. In the bright sunlight of this morning, this coloration was obvious. I think I walked past there once during the last few gray days, and I don't remember seeing anything like this. It looks like some sort of dye. It might be from some trash, as there is what appears to be paper right up next to the vent. In any case, I doubt it is natural, as that pool is intermittent, and when not empty, it's near boiling.

The wait for the next Grand eruption was similiar to the morning. Arrived to a heavily overflowing pool and the subsequent Turban eruption was a long one. The next Turban eruption had no overflow. Unfortunately, the One Burst Grand eruption lasted just under 10 minutes.

May 25, 2020

Observations for 2020 May 24

No new snow overnight, and since it didn't clear, the temperature stayed just below freezing. So the snow on the walkway out to Grand was mushy and sloppy from all the footsteps from yesterday, most of them being ours.

For the first time it appeared that the water level in Belgian was at the rim, instead of being just below it (or even lower). West Triplet was in intermittent overflow. No delays, but we did end up waiting an hour for a double interval of just under 12-1/2 hours, which isn't at all bad.

The eruption of Grand ended at 8m36s, and didn't even try for a second burst, so that made for the eighth consecutive One Burst Grand of the trip. As we left, West Triplet started to actually burst, but weakly. Then as we passed Bulger, Churn started. I managed to get the rest of the eruption on video. It was a nice solid, typical Churn that resulted in the pool dropping about 5cm or so. It took about fifteen minutes to get back to overflow, and we finally left after twentyfive when the occasion boils didn't result in anything looking like an eruption.

Since was early and nice, for once, decided to visit the Lower Geyser Basin. The Firehole Lake Drive was two grooves of pavement in the snow much of the way. Great Fountain wasn't anywhere near overflow, and Fountain didn't look interested either.

At Fountain Paint Pots there were two sets of footprints leading out and back. A Fumarole was completely drown by a large pool, and just bubbling, and not vigorously. Red Spouter was impressively throwing brown soupy mud all over the place. The Paint Pots themselves were so wet that there were bluish pools over some of the area where the mudpots would normally be active.

There were people at the next eruption of Grand, along with some of the Naturalist staff.The wait started out nice, then the snow showers began. They ended well before another One Burst Eruption.

Afterwards another walk around Geyser Hill showed that Beehive was a bit noiser than yesterday, and that there was some slopping, but it just didn't look interested in erupting. Infant Pool being well above the rim was about the only other interesting thing noticed.

May 24, 2020

Observations for 2020 May 23

The snow started just about the time we needed to go out for the morning Grand. We trudged on out there, into the north wind. The temperature was right at freezing, so instead of bouncing off, the snow stuck and accumulated to gloves, hats, coats and packs.

The wait at Grand was uneventful. I did watch a West Triplet overflow early in the wait, then went on down to the main runoff. just before Grand started, a small bird flew up from the runoff channel and tried to land on my notebook pouch. I shooed it away.Because of the wind, the pool was easily visible. Turban Geyser's intervals were consistently about 21 minutes, and the durations just under five minutes.

Then we got a nice fill, and the 21 minute mark passed. At 24-1/2 minutes, Turban started and Grand quickly followed. Thanks to the wind, there wasn't much height to this One Burst Grand eruption which lasted about 10-1/2 minutes.

West Triplet was overflowing as we were leaving, and started to well up and burst. Didn't stay around for the duration, and what we saw of the bursts were pretty weak, so it might have been a short eruption. Bulger did nothing the whole time we were out there.

On the way out, at Castle, we encountered two other people. The guy was wearing shorts, and I overheard him say they wanted to go to Grand.

The snow continued during the day, so when we went back out for the mid-day One Burst Grand, the tracks from our previous visit (and of the other two people) were just barely visible. Again the wind was from the north, so we were able to easily see the water level in the pool.

We had a ten minute wait with a nice full pool when Grand had a boop. Then nothing for almost four minutes other than the pool slowly dropping. A long Turban eruption and this meant we were getting a delay. It was two Turban intervals, another ten minute long eruption where Vent & Turban quit. Afterward West Triplet was in heavy overflow, but all we saw was a single heavy upwelling, no eruption.

Decided that it was time to visit Geyser Hill, to see what it was like. Walk over to Lion under at least four inches of snow, and slow going as the temperature was also just at freezing, making everything mushy. When we got to Aurum, it was having a sequence of nice surges that sucked us in. It continued to do that for the next hour. At some point Castle started, but it was hard to see it. Mostly we could tell it was eruption by the sound.

I finally had enough, and left to look at the rest of Geyser Hill. Lion was quiet, as was Beehive. It was at Beehive where I turned around and saw the large Aurum eruption steamcloud. Went over to Anemone, and then returned back to the vehicle at the store lot via the Sawmill Group.

Went out in the evening and the snow was pretty much ended. There was even, once, a bright spot in the sky to the west where the sun should have been. Also arrived in time for a delay. This time, it took three Turban intervals for the One Burst Grand eruption. If the sun had been visible, it probably would have just set.

May 23, 2020

Observations for 2020 May 22

There was at least an inch of snow that needed removal from the truck before I could drive over to the morning One Burst Grand eruption. But it wasn't cold, as the snow was melting, and the wind was much less than yesterday. But the weather was getting wet as we came back in.

Belgian Pool had recovered mostly, just slightly below the rim. I've seen that variation before.

Did a survey down basin later in the morning. There are new benches at Castle, Riverside and Fan & Mortar, replacing the old ones. Thirty at Riverside, so there will be much less excuse for people sitting on the bumper logs.

Fan & Mortar looked nice at the start of a cycle, with Bottom vent splashing away, and they all quickly died down as Angle started. I doubt there's been any eruption since last year.

Giant didn't look changed much, either. Didn't spend much time there, as the weather was starting to get wet. An extended observation period will have to wait for nicer weather. Oblong has thick black slime filling much of the runoff, so I doubt it has done anything in the last few months, either.

The mid-day One Burst Grand was during a period of snowing, and had a short interval, so we got to see the start from Castle. Waited through the West Triplet activity to catch the first Rift eruption of the season. Again, things seem unchanged there from last year, as Percolator and Sput D were also active until West Triplet ended as Rift started.

The weather cleared a few hours later, so went out to see the Three Sisters activity in person, instead of on the camera. Got confused by which was which, so initially reported Mugwump for what was actually Three Crater. (I think that pool of water has the highest concentration of less than obvious names.) Saw a couple of periods of intermittent splashes to about a foot. The first lasted a bit over 7 minutes, which the second was only four minutes long.

Then it was off to Grand, where we were treated to a 35 minute delay. It was too steamy to see the pool, but on the other hand, the steam was pouring off well below the rim of the crater. Finally, 20 seconds after a couple of boops, the One Burst eruption began. The steam direction was more up the hillside, so was able to catch the starts of Vent and Turban.

Bulger had been having frequent minors before Grand, and the webcam operators had mentioned it looked different. So after Grand, we stuck around for a while to catch one, with no success. The best we got was deep rumbling.

May 22, 2020

Observations for 2020 May 21

The precipitation didn't start until we passed West Thumb, but before that it was gusty head-winds. The notification sign at the junction sound of Lander had "South Pass 50+mph winds".

But it wasn't wet when we went out for the first One Burst Grand of the year. The sun was actually trying to come out. The first geyser I saw was the end of a Tilt eruption. But the interesting thing was that Crystal Spring and Belgian Pool were down about 3cm, and that was higher than earlier. At the same time Slurp was having a wet steam phase eruption-- lots of wet droplets with a hint of the slurping sound.

On the way back, we did get to see the mule deer and bison who have been hanging around together. They were in the trees over by Oval Spring.
