Observations for 2022 August 23


A dull day. When I woke up, I found that Grand was at 7-1/2 hours and hadn't erupted yet. So went out into the fog and cold. Waited through three Turban intervals for a One Burst Grand.

For the next Grand, found that Belgian and Crystal were both high. Belgian was within a centimeter or two of the rim, and Crystal was near overflow.

Grand seems to be developing an interesting indicator for an eruption. There have been several cases in the last few days where there is no Turban Delay Interval. Instead, at some point, there is a Turban eruption without Grand overflow. Grand has erupted on the next opportunity. It's almost as if the Turban eruption prior to the no overflow eruption was a Delay Eruption. But, as in this case, the interval was normal (about 18 to 19 minutes) and the duration for Turban is short.

The no overflow Turban eruption happened before the afternoon One Burst Grand eruption. Afterwards, West Triplet had a period of heavy overflow and thumping with a few small splashes.

As the wait for the late evening Grand eruption started, we were surprised by an eruption of Oblong. Unlike most Oblong eruptions seen from Grand, there was no long period of heavy steam before water was visible (or in this case, audible). Instead, within moments it was possible to see the water in the dim light, and the sound of the eruption was obvious. Otherwise it appeared/sounded normal. Turns out that it was the second of a series.

A half hour later, we got the Castle eruption following this morning's major eruption. It was a short minor, and even from over by West Triplet it was obvious that once it stopped, at around 3-3/4 minutes, it wasn't restarting. Even when we returned from Grand's eruption, it was quiet.

The One Burst Grand was about an hour later, and once again it was preceded by a no overflow Turban eruption. Now that this pattern has been noted, I expect it to not be seen again. As for the eruption, at around 8 minutes, Grand acted like it was trying to quit. That low energy activity continued for another three minutes. When Grand finally quit, Vent & Turban stopped within moments.

Observations for 2022 August 22


An early morning eruption of Rift meant that it was unlikely for Grand to have a short interval. But I did want to be there for when it ended. But first, spent an hour at Fan & Mortar watching some sort of weak cycle where Gold and High never really turned on, and Angle just blipped a few times. Almost like it was trying to go into a pause.

I also checked East Sentinel, and all the grass growing in the runoff and splash zones showed that there hadn't been any eruption this year. The formations on the river side were plenty wet.

Finally went over to the Grand area, where Rift was still erupting. After a couple of Turban intervals, there was a Turban Delay. Before the second Turban eruption after that, Rift finally quit at least five hours after it started. During all the time I was there, Sput D was erupting also, and it quit when Rift did. About a half hour later, Sput D splashed a bit, and then started having eruptions like the ones I've been seeing previous days.

The delay ended up being seven Turban intervals. After the sixth Turban eruption, during a Sput D eruption, Rift began to show some heavy steam, looking like it does just before it starts. The Grand eruption had two bursts, with the pause lasting nearly a minute.

When I left, Belgian Pool was high, with Crystal Spring overflowing and drowning Slurp, which was actually in full slurp mode instead of being a wet fumarole.

But when I returned to the area for the next Grand, both of those features were well down, maybe as much as 20cm. Bulger was noisy but during the Grand wait it never erupted.

That Grand wait was long, as after three Turban eruptions there was a Turban Delay followed by seven more intervals. Once again, we got two bursts from Grand. The first burst ended at 8m22, which is short enough to be a One Burst Eruption, but Grand quickly had the second. The whole eruption lasted less than 10 minutes, and Vent & Turban actually continued.

It was also a night for idiocy. First it was a noisy, loud family walking to Morning Glory and back shining flashlights everywhere and shouting at each other. Then it was someone riding their skateboard down the walkway from Castle. The steady headlight and sound on the walkway made it appear to be a bicycle.

Probably waited about 15 minutes for a Turban Delay Interval. The lack of overflow from Grand for the next Turban eruption tends to confirm that. Shortly after that Turban eruption, Oblong erupted. A steamy eruption with several tall bursts on a fog-free, windless morning.

The third interval after the Turban Delay resulted in the One Burst Grand eruption.

From there, went on down to Fan & Mortar, where a couple of hours wait resulted in a weak cycle, followed by a stronger one. During the first cycle, High and Gold never looked even close to having that "is it trying to go into eruption" look that seems to occur during most cycles. Angle was off during most of that time, until the end stages.

The next cycle started quickly, with Angle on within minutes of the start of River, High and Gold. But they also had much higher water levels than before. Angle then quit, and wasn't active again until near the end of River activity.

While sitting back on the abutment in the shade, I had a weasel run across the bridge right in front of me and disappear down the slope. Might be related to the one I saw in the same location last year.

Early afternoon, and arrived at Grand with Turban erupting. Thirty minutes later, Grand was low as Turban started erupting. Grand's pool refilled, and Grand erupted about 55 seconds after Turban. During this One Burst Eruption, Grand had distinct slow-downs at around 7-1/2 and 9 minutes. They weren't quite false pauses, because there wasn't the usual tall jetting afterward.

Went back to Fan & Mortar for more observations, in which we saw a moderate cycle that included steaming from the frying pan areas near Lower Mortar. I left after an hour, only to get back to the cabin just in time for the radio call that there was a splash in Fan's Main Vent.

Got as far as Grotto when another call announced that that was the only splash, and the activity didn't look promising. As Grotto Fountain had just started, I watched it erupt along with the start of Grotto.

At Fan & Mortar, the unpromising start turned into a pause, with some more Main vent splashing. But when River and the rest of Fan started up, the activity died down. After that, suddenly the frying pans were quite steamy, with the Frying Pan vent pouring out water.

There as one more Grand eruption for the day, and it appears we arrived for another Turban Delay Interval. This time the delay was for only two Turban intervals. The first burst lasted 9m19s, which often results in a One Burst Eruption. But by bright light we could see the water sloshing around in Grand's vent. It took about 45 seconds for the second burst to start. The second burst could have stopped in time for a possible third, but the second half consisted of lethargic short jets.

Saw Oblong erupting while walking through the Sawmill Group headed for Grand. At Grand, waited a couple of Turban intervals, and then got the Turban Delay Interval. Took Grand three more intervals to recover and give us the One Burst Eruption of the morning.

Went on down to Fan & Mortar. Arrived as the Fan vents were getting quiet. Upper Mortar was rumbling a bit. And I saw some steam from the Lower Mortar frying pans.

A few minutes later all the Fan vents were quiet, including Angle. Except for a brief series of splashes a couple of minutes later, Angle stayed off for the next 52 minutes.

About a half hour after the vent went quiet, Bottom started splashing, and it could even be considered to be in a weak eruption. The runoff channel near the vent got wet during that time.

Shortly after that, River came on, and a couple of minutes later High and Gold came on strong. Five minutes later, Angle joined in. Twenty minutes after that, all the vents seemed to shut down, and Angle was still quiet when I left ten minutes later.

For the first time this year, I saw an actual normal cycle, and Angle quiet for more than a minute or two. Since it's been well over 2-1/2 days since the previous eruption, this fits in with the belief that they have recovered and have the potential for more eruptions.

Once again, Oblong erupted right as I arrived at Grand. The wait was another one of those cases where the Turban eruption durations and intervals slowly decrease. This time, the interval only had to get to 17-1/2 minutes before Grand would erupt. Sometimes it waits until Turban's interval gets near 16 minutes.

Even though the first burst lasted 9-1/2 minutes, which is more than long enough for a One Burst Eruption, we got a second burst. The water in Grand's crater sloshed about for almost a minute.

Observations for 2022 August 19


Two minutes after we arrived at Lone Star, while we were tying up our bikes, it began a major eruption. Spent about ten minutes watching the eruption, then headed off toward Shoshone Geyser Basin.

As expected, the hike in took more time than previous trips, as it's been six years since the last visit. Went in this time because we were able to piggyback on a research permit which would allow some time on the west side of the creek.

On the way in, we got to see the trail crew in action. One section of muddy walkway, just beyond the last thermal area on the trail from Lone Star, had already been replaced. Another section, the extremely muddy walk just before the start of the upgrade to Grant Pass was in progress. Was surprised to see that it was being built over steel beams, and should last a while because of that. But for now, that meant walking over the wet area on the planks of the former walkway, laid down haphazardly as a detour. Definitely had to watch your step on that.

Otherwise the walk to basin was uneventful. We arrived at just after 10:00, and went on toward Minute Man Geyser. The pool was in overflow, and Minute Man itself was noisy. We got the first eruption of the series a few minutes later. For the next three hours, it would erupt with intervals between 50 and 90 seconds.

Across the creek we saw activity from Velvet, Lion and other features that I'm not familiar with. There was also a deer grazing way back near the trees. We met up with the permit holders and split up, with one team across the creek while others stayed to make contact with those on the trail. Just as part of our group was about to cross over, Bead erupted. At that point Shield and Gourd also started, and they seemed to be active most of the rest of our visit.

So I was on the east side for a few hours. Watched and timed Minute Man, then did a survey of the other features. Triple Bulger was erupting from the nearer vent (I believe that's the blowout.) Never got any good timings, but some of the bursts were 1.5 meters high. Double Geyser was overflowing steady, with a stream of bubbles rising from one of the opening. Little Giant was quiet, while the new feature next to it seemed even larger, erupting vigorously to several meters at times.

We also made contact with several groups who came in from the lake landing to the south, as well as the Shoshone Lake patrol ranger. One of the groups had intended to spend the day exploring the area, and were surprised and disappointed to learn that the area was closed, and the best they could do was to see the western features from viewpoints along the trail. I think they also planned on doing some hotpotting.

Finally crossed over to the west side of the creek, just in time for another eruption of Bead. Then we got the first of a few spells of light sprinkles. Spent some time around Velvet, which was having intervals of about 12 minutes. Over by Coral Spring, we saw Diverted Geyser was quiet, and it started while we were there. It appears that it is usually active, so we were fortunate to see it quiet.

Did a run up to Boiling Cauldron. The sluiceway seems the same, while I'm sure the details have changed since my last visit. The bison skeleton in the nearby deep pool has become harder to pick out.

Over at the hot pot, despite the area closure, the beaver dam was in place. The boiling spring that supplied much of the water was not overflowing, so the only water source was the boiling ragged vent next to the creek. The tree which had fallen over it just before my last visit had left a pile of needles on the ground near the spring, and all the branches were blackened but in place. (I need to check, but I thought back then that pool was point onto the tree, which I thought might cause some silicification.) The little "Anthills" were all dry and quiet.

The trip back was interesting. We started back at 16:00, and until we got to the construction zone, there was constant thunder in the distance. But it never rained. I also learned, about a mile into the hike back, that my old hiking boots were finally falling apart. The sole on the heel of one was completely detached and flopping, while the other was threatening to do the same. So for the next five miles I tried to watch how I was walking and where I was stepping so I would not tear them any further. That slowed us down a bit, but I made it back to the bike without having to resort to my river crossing sandals. And my feet felt fine when we finally got to the bikes at Lone Star.

Get back into the area and learn that it's been 5-1/2 hours since the previous One Burst Grand eruption, so of course we need to go out there, even if it is after sunset.

Ended up not having to wait. Turban made a noise, and Grand immediately had an explosive start to the One Burst Eruption. There was just enough light that we didn't need to illuminate the eruption.

And while Grand was erupting, Castle started. Didn't realize this until after Grand had quit. By the time we got over there, it was already in steam phase, and with the wind, getting the entire walkway up from the bridge wet.

Turns out that Fan & Mortar erupted shortly after sunset yesterday. By this morning, they had recovered and looking like they were having Events (Main vent splashing, etc.). But the water on the boardwalk and the splash zone flowing into Backwater and the full catch basins pretty much confirmed what had happened.

So it was on to Grand, where we arrived just in time for a Turban Delay Interval. The only remarkable thing about the followup was that it took only four Turban Intervals before we got the One Burst Grand. Three or five is much more common, but the buildup to the eruption was obvious minutes before.

Just couldn't stay away, so back out at Grand well after midnight. Less than an hour's wait for the One Burst Grand eruption, which started with a nice explosive start by Grand. Since the moonlight was still bright, didn't illuminate the eruption and get the start times for Turban and Vent. Did brave the rain to the north to make sure that Vent did start at around the four minute mark.

With all the relatively short intervals since the last Rift eruption, came back out in the morning with an expectation of a short wait. That didn't happen. Instead had to wait nearly three hours for the One Burst Grand eruption. No Turban Delay intervals, just Grand never showing any signs of trying to erupt until the the final interval.

Right after Grand ended, Oblong erupted, which seems all too common lately.

During the wait, the water level in Belgian rose from being well below the second lobe (down maybe 10 cm) to having standing water in the lobe. Also toward the end of the wait for Grand, a small amount of sizzling was visible in Sputnik during the eruptions of Sput D. The intervals for Sput D's eruptions varied from 10 to 25 minutes, and I don't think I missed any, and there didn't seem to be any pattern to them.

Right after Grand, before we could untie our bicycles, Castle started erupting. This turned into a long minor eruption, over ten minutes long, with lots of pauses during the last three minutes.

It was a nice wait before sunset. Once again Grand did not have any Turban Delay Intervals, but two Turban eruptions before Grand erupted, there was a short, powerful Turban eruption, followed by a short Turban interval. It's almost as if there was some sort of delay going on.

The eruption started with a series of boops. It ended at 8m42s, and finally had a huge second burst. Following that the pool drained with no attempt at another burst, despite the duration only being just over ten minutes. And then Vent and Turban continued to erupt.

Belgian Pool was quite high by then, and it sounded like Crystal had even managed to drown Slurp a little. West Triplet also overflowed heavily after the Grand eruption, but no attempt at bursting or erupting.

When saw that Rift was erupting, decided to get some more sleep. So surprised to learn that Grand erupted as Rift ended. Did come out for the first overflow, which at 4h20m, seems longer than non-Rift first overflows by about a half hour. Also, that Turban interval was essentially a Turban Delay Interval, as it was over 30 minutes long. When I arrived Crystal and Belgian were still at a high level, with water in Belgian's lobe, but when left an hour later, Belgian was now down about 1cm below the lobe level.

Just after first overflow from Grand, Bulger started a major eruption. Within a minute, Bulger's Hole was full and starting to erupt. The eruption lasted about 40 seconds, and Bulger had a short 6-1/2 minute eruption itself. Also noticed that Sput D/Delta was having occasional steamy burst as if it was trying to erupt, but didn't have any water.

Coming back out for the Grand eruption, Belgian and Crystal had dropped even further. In quick succession we saw Grotto Fountain, Grotto, Oblong and Daisy. It was a bit of a pleasant surprise for Grand to erupt about a half hour later on only a seven hours interval. After the first burst ended, water sloshed around in Grand's vent for about a minute before finally draining.

Came out at sunset for another Grand eruption, expecting to see it in the dark. Right after sunset we saw a coyote run across the rocks at the top of the slope trying unsuccessfully to harvest a marmot. It hung around for a while, but eventually gave up and headed north.

By then it was apparent that we were having a Turban Delay Interval. At 28 minutes, Grand had several boops, but the pool stayed high. Two minutes later it booped again and then started an easily visible One Burst Eruption. Around 9m45s there was a false pause, and eruption continued for another 1-1/2 minutes.

Just before the false pause Castle started its eruption. And for once, it wasn't a minor.

Observations for 2022 August 15


When I checked, it seemed like the sky was clear and the moon bright. But by the time we gout out to Grand, it was fogging up, and calm. The steam for the two Turban eruption intervals we had to wait kept changing direction, so hard to tell where to go when the eruption started. It rained at the north end, so the walkway by West Triplet it was. Turned out to be a nice view from there, and we even got a second burst. By that time, the fog was thick, with Geyser Hill invisible from Crested Pool.

As we rode past the Inn, Old Faithful had a large pre-play surge. We stopped, and then the eruption proper began. At 03:00, it can be an impressively loud geyser, even from our vantage point between the benches and the bike path. It was also not foggy there, as the fog was drifting down basin.

By the time for the next Grand eruption, the fog had burned and been blown away, although it was still cool and damp and the sky was overcast. This time only had to wait for one Turban eruption interval before we got the One Burst Grand eruption.

For the third Grand eruption of the day, the wait was even shorter. Arrived well before six hours since the previous Grand eruption, and two minutes short of six hours, Grand had a series of large boops that started the eruption proper. In the middle of the afternoon, the benches were practically empty.

After that, spent an hour and a half at Fan & Mortar. It was having cycles similar to what I had seen a few days before the eruption. While Angle was mostly on, the rest of the vents would start and stop with discrete pauses between the activity. During that pause time, I noted that the noise from Upper Mortar would increase, and Bottom Vent would have occasional splashes.

After sunset, headed out for one more Grand for the day. The water level in Belgian Pool and Crystal Spring
remained high all day, with water well into the lobe at Belgian, and Slurp being drowned by a trickle of water from Crystal.

Did not get a Turban Delay interval, but still Grand waited until half hour before midnight to erupt. The sky was light behind the One Burst Eruption, but the moon was still well behind the ridge. Sort of the reverse timing of Grand waiting until just after sunset to erupt. But we did get to see a total of five bursts over four eruptions today.

Decided today was a good day to visit some backcountry geysers.

After yesterday's storms, it was damp, cool, gray and foggy. Left from Fountain Paint Pots parking lot at 09:00, and arrived at Great Fountain by 09:20. The pool was high, but yet at overflow. So went back to Pink Cone, where we spent 45 minutes eating breakfast and seeing nothing happen. Returned from there back to Great Fountain.

We found it had just started to overflow. There was steam coming from the pool outside the crater, but no overflow off the inner terrace. As we waited, the fog finally cleared, revealing blue sky, but there was also no wind, which made it hard to determine which place might be the best place to see the eruption start. Also during the wait, saw five eruptions of White Dome.

After at least 72 minutes of overflow, Great Fountain went from big boil directly into erupting. It wasn't a great start, and the second burst wasn't all that good, either. But the third burst started with several surges that put water over the edges of the terraces.

It was after the first burst that the only other people we saw passed by. A couple of people more interested in bicycling, as they didn't stick around for the eruption after a couple of minutes.

We left after the third burst to go to White Dome. After having frequent eruptions during the wait, it was over a half hour later and no sign of an eruption. During that time, Great Fountain had its fourth and fifth burst, and both of them had surges that looked nicely large from our vantage point.

During the wait at White Dome, we did see an eruption of what might be WDG-1. But it only lasted two minutes.

After finally giving up on White Dome, we then saw Pink Cone in eruption. Not sure how long it had been erupting, but an hour later it was still having strong resurgences every time it looked like it was ending.

Late in the eruption we saw an eruption of Bead, and just before leaving, Narcissus and then Pink erupted.

Got back to the Upper Basin to find that Beehive hadn't erupted as expected. So pleasant surprise to hear the radio call about the Indicator. It was a short Indicator, and arrived just as Beehive started.

Later it was time to go to Grand. Got there on what looked to be a Turban Delay Interval, and the lack of overflow from Grand before the next Turban eruption tended to confirm that. If Grand had erupted on the second or third Turban eruptions after the Delay, we'd have been able to come back inside before the rains started. As it was, we got wet, and had to wait until the eighth Turban eruption before Grand finally had the One Burst Eruption. This took place just after the sun disappeared behind the ridge, so between the steam from the humidity and the lack of sunlight, it wasn't particularly good looking eruption.

And then, as we were leaving, Oblong had an eruption.

Spent over and hour at Fan & Mortar. Unlike sits last week, there was not real pattern to the activity, with River, Gold and High turning off and on, and Angle sputtering away the whole time. Not surprising, but was hoping maybe Angle would quiet down a bit.

At Grand, arrived in time for a Turban Delay Interval with multiple Grand boops. Then a series of eight more Turban intervals before we got the One Burst Eruption. The wait was hot and humid and windless. The clouds were building with occasional thunder, but it seemed they never provided much shade.

Kept expecting the rains to start during the wait at Grand, but it was actually over an hour later. They lasted into the night, and I decided to let someone else enjoy a One Burst Grand in the dark.

Observations for 2022 August 12


After midnight there was high thin cloudiness with occasional thicker clouds. Most of the time the area was brightly lit, even when the moon went behind a cloud. Got out to the Grand area for a twenty-five minute wait for a Turban eruption, so we definitely had to wait through a Turban Delay. But we only had to wait through two Turban eruption intervals for the One Burst Grand Eruption.

About an hour later, Fan & Mortar had the first eruption in several months. Before going to Grand for the early morning eruption, I went down basin to check things out. There was definite wash zone beyond the walkway with runoff into the Backwater Spring area. The catch basins between Upper Mortar and the river were full, and all the vents were completely quiet. What was interesting is that there wasn't much evidence of flow down from Bottom Mortar to the river. I would have expected there to be pooled water there.

The One Burst Grand eruption came after a Turban Delay interval and three more Turban eruption intervals. It was followed shortly after by an eruption of Castle, the followup to last night's pathetic minor eruption.

The afternoon saw the forecast thundershowers finally appear. Went out to Grand after one ended, and was sweltering in my raincoat by the time I arrived because the sun came out and the wind died down. But then the rains started for a bit, and the coat went back on.

But wasn't a long wait. For whatever reason, after a day of long Grand intervals following the Rift eruption, Grand has reverted to shorter intervals.

The start of what turned out to be a unique eruption caught me a bit by surprise, as I didn't start the video recording until it had started. I try to capture the lead up to the eruption through the Grand start until Vent reaches full height. During the past week, the Vent start has been as late as four minutes after Grand's start, especially if Turban is also slow to start.

From my location, it was sometimes hard to see Vent due to the way the steam was swirling around. But as five minutes approached, I realized that I could see Vent clearly, and it wasn't erupting. A few years ago, I saw an eruption of Grand where, if I remember correctly, it took over seven minutes for Vent to start. Seven minutes became eight this time.

At 8m42s, Grand's first burst ended. It was strange to see just Turban erupting with the water in Grand's vent sloshing around, and no Vent eruption off to the side. The sloshing built into a tall second burst (my first of the trip), and when it ended, there was still no Vent activity. That's when I definitely saw water in Vent for the first time. Grand sloshed a bit like it might try for a third burst, then drained. The total Grand eruption duration was exactly ten minutes. It took Vent a minute after Grand's end before it finally started. It built up as normal, but unlike most post-Grand activity, it was tall and not steamy. (It occurs to me that if there had been a third burst, Turban would probably have quit, and Vent may not have started at all.) Waited to see what Grand might do, but after about fifteen minutes there was still no afterplay.

Came in just in time to miss the showers and then heavy rain for the next few hours.

Back out well before midnight. It was mostly cloudy, with frequent lightning to the north. Waited about an hour with no decrease in the lightning, with occasional thunder from a strike that was probably in the Lower Basin. During the same period, the sky near the moon was starting to clear.

Turban started the proceedings, and the moon was still behind a cloud at that time, so we illuminated the start of the Grand eruption. But within minutes, before Vent started, the moon cleared the clouds and we were able to watch the One Burst Grand eruption backlit. Vent itself started at the expected time, but under the conditions, it appeared to be taller than usual.

Observations for 2022 August 11


Could have gotten out to the morning Grand eruption if I'd been a bit faster in getting up and moving. Not too surprised that the Rift effect had finally wore off.

Finally got out for the next, noontime Grand. Only waited one Turban interval for a One Burst Eruption that lasted less than ten minutes.

With nothing much better to do, spent an hour or so in the Bijou Monkey Cage. For much of the time, Bijou was quiet or showing only small splashes. Then every so often, it would pick up in activity, joined by splashing in Catfish. In less than a minute, it was back to mostly quiet. Only once did I see any sort of splashing from Mastiff's back vent. The platform itself was dry except for what was probably a puddle left over from last night's showers.

As I was about to untie my bike, Grotto had a Central Vent Delay. Hung around for a while, but nothing much else, other than a lot of rumbling, happened over the next half hour.

Was about to go out for another Grand eruption when got the call that Beehive's Indicator was in eruption. That was surprising, because yesterday's Beehive eruption was so late that today was expected to be a day that Beehive would skip erupting. Since the start of the Indicator was known (turns out it had been erupting for well over ten minutes) I decided to watch it from the bike trail. It started as I passed the Inn, and across from the parking lot got some nice rainbows.

Beehive Geyser Rainbow

Got out to Grand finally, and the pool was full. No waves, but did get a couple of boops. That alone was enough to indicate that this was some sort of Turban Delay Interval. Unlike the other recent ones, we only needed to wait two more Turban Intervals before Grand (preceded by another large boop) erupted. Once again, the One Burst Eruption lasted less than ten minutes.

Since it had been 18 hours since Castle's middle of the night major eruption, joined the crowd over there waiting for the next eruption. Waited almost 40 minutes, with Castle slopping and even acting like the eruption was starting. I commented that we were going to get a three minute minor eruption.

After waiting 40 minutes, the eruption finally started. Castle had a short pause during the first minute, and pauses were frequent after that until it finally gave up about five minutes into the eruption.

Since we were in the area, stopped by Norris to watch New Crater/Steamboat do nothing for a couple of hours. The runoff channels are slowly turning white from deposits.

Back in the Upper Basin, had a short wait for a One Burst Grand Eruption. It was preceeded by a large boop about 20 seconds before the start.

Just before sunset, Beehive finally erupted, and I watched it from near Sawmill. At Grand, there wasn't any Turban Delay Interval, but the Turban eruption intervals slowly got shorter of a period of two hours. The One Burst Grand Eruption started on a 15 minute Turban interval, and it took over 50 seconds to finally get started.

Shortly after the Beehive eruption, there was a report by Xanterra maintenance of a bear with two cubs sighted behind the Lodge. Sounded like it was over near where The Box used to be. No further sightings, but the trail to Observation Point was closed today due to bear.

There wasn't a Turban eruption delay associated with the morning One Burst Grand eruption. Castle finally had a major eruption shortly afterwards, and then Oblong also erupted. So watched Oblong from near Rift, then went over to watch the steamphase on Castle.

Spent a few hours waiting for the afternoon eruption of Beehive. Was not hot and not windy, which made Geyser Hill actually pleasant.

There was a Turban eruption interval delay for the next Grand eruption. With the shorter Grand intervals, was hoping that this delay would only be for two or three Turban eruption intervals, but ended up taking five eruptions. Once again, it was a long One Burst Grand eruption that we saw, but with nice rainbows, especially after Vent started.

Went out to wait for a moonlight Grand eruption at six hours since the previous eruption, and got to see Rift instead. West Triplet was completely dry, indicating that Rift had been active for quite a while. By bright flashlight, was able to see patches of steaming at Sputnik and Sput F3 behind it. Belgian had already dropped out of the lobe. Walked up on an eruption of Tilt on the way back.

Went out with the expectation of a short interval, since Grand finally erupted four hours after the Rift observations. On the second Turban eruption, got a Turban Delay Interval. Grand finally had the One Burst Eruption nine Turban intervals later. On the fourth Turban eruption, there was no overflow from Grand, as it the third eruption had been another Turban Delay.

Early in the wait, did see a long Bulger major eruption, but there was nothing from Bulger's Hole. Before the Delay, also got to see a nice eruption of Oblong.

The wind allowed for the viewing of Beehive from the south for once, and only during a brief time was there a threat of getting wet. For much of the eruption, it was dead calm and water was falling all around Beehive's cone.

Went out for Grand just before sunset. At around the 6-1/2 hour mark, got a Turban Delay Interval where Grand had multiple boops over a period of a minute. Knew from that that we were in for a long wait.

Turned out to be ten Turban eruption interval long wait. This time the intervals between Turban eruptions slowly decreased, so that just before the One Burst Grand eruption, there was an interval of 16-1/2 minutes. Grand and Turban started almost simultaneously after an extended boil from Grand, and the duration was well under ten minutes.

During the wait we did get to see a strong Penta steam-phase eruption.
