Category: Activity Report

For a double interval, the wait for the One Burst Grand eruption wasn't too long or cold. The eruption itself was nicely backlit but otherwise undistinguished.

Decided to ride the bike over to Biscuit Basin for some photos. There were a fair number of people pulling up to the close entrance road while I was there. None of them actually got out of their vehicles or even turned off the engine.

Sawmill was in eruption when I went out to see Grand, and was still in eruption over five hours later. With a deep drain in progress, I started taking some videos of the area. Got Oval Spring having constant low pool surging, some Spasmodic northwest vent activity, and a Penta steamphase minor. By that time Sawmill finally stopped, so it was time to transfer attention to Uncertain, which started looking good during the Penta activity. Fortunately, it took its time. During the wait, I managed to record a couple of low pool, no overflow eruptions of Sawmill, and finally got Uncertain erupting.

By the time Uncertain had finished, it was time to move over to Grand. We were over 7-1/2 hours into the interval when Beehive's Indicator was noticed by the NPS. So once again, the benches at Grand emptied. The Grand eruption started right after the end of Beehive's eruption, but it was a nice but short two burst eruption, so most who had went to Beehive made it back. The eruption lasted less than ten minutes, and there was no attempt at a third burst.

When we arrived at the Fountain Paint Pots parking lot, there weren't any lights in the distance. We quickly got our gear together, and were about to leave when sudden there were lights and the sounds of people yelling. We hurried over and caught about two-thirds of the second Morning eruption of the year. It was nicely illuminated by several torches, and there was no wind, so Morning was not hidden behind Fountain and Clepsydra steam clouds. After Morning ended we stuck around for the Fountain eruption, which lasted about three quarters of an hour.

When we returned to the cabin, it was time for Grand. We had just arrived when Castle started to erupt. A few minutes later I heard some booping, and we got the One Burst Grand eruption. There was a slight breeze which helped move the steam away from our view. Unfortunately, it was another short eruption with no attempt at a second burst.

By this time Castle was in full steam phase, so we spent a little time watching it slowly die down.

The call for Beehive's Indicator went out around 23:00. With all the long durations, that meant plenty of time to get properly dressed and prepared for a calm, well lighted eruption. Little Squirt was also active at that time.

I missed it, but it turns out that at the same time, Rift was erupting. Not sure when it started, or for how long it erupted, but the next morning at dawn I found Grand an empty crater, and Turban had what appeared to be a normal eruption, so the previous interval wasn't excessively long.

Came back out about 2-1/2 hours later and Grand was well into overflow. Then proceeded to wait for nearly four hours for the mid-day One Burst Grand Eruption. As with many recent eruptions, this one started with a series of boops over a period of about ten seconds.

After lunch, caught the mid-day Beehive eruption. For some reason, the boardwalk was nearly empty, despite (or because) an Old Faithful eruption being due. Old Faithful had a large preplay midway during the eruption of the Indicator, which ended up causing both geysers to start erupting within moments of each other.

The Sawmill eruption I saw start in the morning finally ended shortly after Grand, so after about 2-1/2 hours, I went out to wait for Uncertain. Sawmill was first rising, then started to drop. About this time Uncertain began to splash up, and we could see the water level in the vent. This level kept getting higher as Sawmill dropped. Finally Uncertain started to overflow. This lasted about 15 seconds, at which point the eruption finally began.

The next interval for the One Burst Grand eruption was surprisingly short. I expected it in the dark, but it was light enough to record video of the eruption, which once again started with a prolonged series of boops.

As I was leaving Uncertain earlier in the day, I heard the radio call announcing that Morning Geyser had erupted. With Grand erupting sooner than expected, we decided that it made sense to at least head out there and see what might be happening. There was a small group of people who had heard of the eruption and were hanging around there. Waited for the crescent moon to set, about 45 minutes, during which time nothing happened. Water level was out of sight in Fountain.

As we were leaving, we saw a light approach from the Paint Pots. Suddenly the light veered off the boardwalk at the Volcanic Tablelands sign and headed north toward the trees. I had the powerful flashlight and lit the person up. He immediately and quickly headed back to the walkway, then continued toward us. For the next half hour, he wandered around the area as if wanted us to ignore him. In any case, he finally drove off.

It's true that we harassed him, but I would have ignored him completely if he had stayed on the walkway. As it was, I wonder if he had a campsite over behind that sign. Too bad for him Morning erupted.

Was quite surprised to learn that Grand erupted shortly before dawn. Had expected (and planned) on it erupting several hours earlier. The interval was so long that I suspected a Rift eruption, but when I got out there, it was obvious that Rift had not erupted overnight.

So instead I spent some time taking videos in the Sawmill Group. Got to see heavy bursting from Spasmodic as it dropped, Oval Spring having good size bursting from the north (front) vent, multiple eruptions of Tardy, the end of a Sawmill eruption, and a Penta steamphase minor.

Missed the start of the last item, as I was set up to record Bulger and Old Tardy (which ended up doing little to nothing), but quickly moved the camera over to Penta. Once that was over, it seemed like activity in Bulger did pickup a little.

After Sawmill restarted, I took a break, and got back in time to begin waiting for Uncertain. At first Uncertain was making lots of gurgling sounds, with an occasional visible splash. Then, quite quickly, Uncertain became quiet. That turned out to be due to it rising in the vent. We witnessed a couple of floods coming from the vent before one of them triggered the Uncertain eruption.

After that, it was a bit early, but still time to wait for Grand. I wasn't paying close attention when I realized that Grand's pool was full and having small waves at the six hour mark. Got the camera started in time to capture a couple of the strong boops. As expected, the pool level quickly dropped well before Turban finally erupted.

Three Turban eruption intervals later, we got a repeat of that performance. This time there were at least five boops, with several well over a meter high. Turban finally erupted just after the 25 minute mark.

So once again we had to wait three more Turban eruption intervals. This time the pool filled early, around the fifteen minute mark, but did start having wavelets until several minutes later. Again, there was some booping from Grand, but this time we finally got the One Burst Eruption, which lasted well over eleven minutes, with Vent & Turban quitting within a minute, and restarting within another six minutes.

The next Grand eruption would be in the dark. Unlike the last few intervals, however, the wait for this One Burst Grand was short, only 6-1/2 hours. The Turban eruption interval was not quite long enough to be a delay. Once again the eruption started with several boops. We heard the first one in the dark, 15 seconds before the eruption.

Did another half-hour video of Sawmill erupting, with Tardy frequently active. About a minute after I stopped recording, as I walked past Belgian Pool, Sawmill quit. Which was something I would've liked to have recorded.

Did not participate in the long wait for Beehive to erupt, but did get out for the 25 minute long indicator. Once again, it was a mostly windless eruption, although there was an attempt at the breeze moving the spray toward the boardwalk.

In the evening, Grand was set up again for a sunset eruption, but unfortunately there was a real Turban Delay interval of nearly 33 minutes. The One Burst Grand didn't occur until six more intervals had passed, but it was still light enough to see details in the pool. There was a sharp false pause just short of the eight minute mark, and the whole eruption lasted just nine minutes. There was no attempt at a second burst, but at least Vent & Turban continued.

It appears that overnight there was at least one long Grand eruption interval, since it was a double interval of sixteen hours. Otherwise the One Burst Grand was the common variety where it lasts less than 10-1/2 minutes. Vent & Turban seemed like they tried to quit, but then the activity picked up considerably, with Vent roaring as if something else could happen.

In the evening there was another long series of Turban eruptions without there being a Turban Delay interval. During that time we saw a couple of Daisy eruptions and a nice tall and wide Oblong eruption. Two Turban intervals before the Grand eruption, we had what appeared to be an attempt at an eruption. That eruption was also short and weak. The next Turban interval after that was one where Grand had little to no overflow.

The Grand eruption started at about the last possible moment. It was two bursts, with the second burst starting with Grand's pool in the shadows. A faint rainbow was visible near the top of the water column, which shows how low the sun was. That burst also lasted almost 2-1/2 minutes, with much of that time taken up with Big Sawmill mode.

For the morning Grand, once again had a short wait for the One Burst Grand eruption. West Triplet did overflow for a while after the eruption, but this time there wasn't any convection or thumping.

Going out for the next Grand eruption, as I passed Crested Pool I noticed that it seemed the ospreys were making a bit of noise. Then I saw the reason-- there was an eagle flying low headed upstream.

The wait at Grand was a long one. As we approached the eight hour mark, Grand finally looked like it might erupt, only to suddenly drop and then sit for long enough for it to be a Turban Delay interval. As expected, Grand finally had it's One Burst Eruption four Turban eruption intervals later. After the eruption, I noticed that the runoff from West Triplet was wet, indicating that West Triplet probably had a decent overflow during the Grand eruption.

Before the Turban Delay, Beehive's Indicator was called over the radio. Not only did this cause a mass evacuation of most of the gazers who had been waiting, but it appeared that many of the visitors followed them, as the benches seemed empty.

After Grand erupted the Sawmill Group was in the proper state for an Uncertain eruption. Uncertain was noisy, but there wasn't much splashing. After waiting about half an hour, suddenly Uncertain's vent filled with water, and with 15 or so seconds, the eruption started. As the Uncertain eruption was ending, Sawmill started to erupt. That eruption lasted for about 50 seconds, and then all was quiet.

Once again out at dawn in case Grand ignored the Rift eruption and had another shorter interval. There were three bison grazing on both sides of the bike trail just across from the store as I rode out. It was warm enough that there wasn't any ice on the walkways, and the sky had cleared enough that the sunrise wasn't brownish-orange. Didn't have to wait long for the Grand erupion. While the first burst was moderatly long, the second wasn't totally unexpected.

Spent the rest of the morning at Artemisia, which showed no signs of trying to erupt.

The afternoon Grand also had a short wait. Despite the One Burst Grand lasting over ten minutes, the pool refilled enough to be seen sloshing about for about fifteen seconds before finally draining.

It was not quite dark when I pulled up to the bike rack and Castle started to erupt. Unfortunately, it was a six minute minor.

So went over to Grand where I noticed that West Triplet had a wet runoff channel. Then waited one Turban interval for the Grand eruption. Turban started the eruption, but with the bright lights deployed, we could easily see the strong waves and boops. It had two bursts, and lasted just under ten minutes, with no attempt at a third burst. It's interesting how these short two burst eruptions cause Vent & Turban to quit.

Got out early because there were no reports of any activity overnight. Arrived at Grand near the six hour mark, and the pool was full, indicating it had been more than a few hours since the previous eruption.

Caught a Castile minor eruption, then two Turban eruption intervals later got the One Burst Grand eruption. When I arrived at Grand, the boardwalks were clear, but were slippery with ice by the time Grand erupted.

Then it was time to revisit Artemisia to look for a part from my camera tripod that was last seen after yesterday's eruption. (I found it.) Also took the opportunity to record some video of East Sentinal boiling heavily.

By the time I arrived back in the cabin, the start of Beehive's Indicator was announced over the radios. So went out for a nice eruption with calm winds and a double rainbow.

Early afternoon I arrived at Grand to what was probably a Turban Delay interval. I didn't see enough of that interval to be sure, but all the other indications (long Turban eruption, no overflow from Grand on the next Turban eruption) were there. The Grand eruption may then have been the fourth after a Turban Delay. Turned out to be the first observed two burst eruption since the three burst eruption. The duration was less than ten minutes, and Grand made no attempt to have a third burst.

With Rift erupting, decided there was no point in going out for the next Grand eruption early. I finally arrived at about the eight hour mark, just after the end of the Rift eruption. The Turban intervals and durations were both short. Ten minutes before midnight, Grand suddenly erupted. The eruption was over before midnight. It appeared that there was no attempt at refilling and having a third burst.

On the way out to Grand, in the trees across from the signs near the store, was a bison. I didn't see it until I passed it on my bike. The bison never looked up, as far as I could tell.

Figured the double Grand eruption interval would put the eruption well into the morning, so didn't head out early. A report of Grand not overflowing with a Turban eruption helped narrow down the time, too.

After 45 minutes, we got a long Turban Delay interval, which fixed the prediction quite a bit. The One Burst Grand eruption was four Turban eruption intervals later. The duration was a disappointing 9-1/3 minutes, with Grand making no attempt at a second burst.

Afterwards it was pointed out that an Artemisia eruption hadn't been seen since yesterday. It being a nice warm day with only a slight breeze, I decided that here was the opportunity to make a video of an eruption. Only had to wait about 1-1/2 hours, and suddenly heard and felt some thumps. The wind was away for most of the eruption, so had an excellent view.

Then on the way back, just as I approached the Lodge, came the call that Beehive's Indicator was starting. So went on over for that eruption. The wind was still a bit variable, and I had to get out the umbrella even though I thought I was in the safe zone at the eruption start.

Finally got a late evening eruption of Grand. No Turban Delay intervals, and the interval was only about 7-1/2 hours. The One Burst Grand eruption lasted just over ten minutes, and once again, there was no attempt at a second burst.

		      Grand: 19m29s

While leaving, noticed that Spasmodic was just starting overflow. Uncertain wasn't making much noise, but Sawmill was high. A few minutes later Sawmill started. Penta, meanwhile, was showing water splashing in the Top and Bottom Vents. This activity continued for about 1/2 hour, during which time Spasmodic dropped below overflow. Penta was still splashing around as I left.

Coming back from dinner in the Bear Pit, I was riding my bike when I encountered an animal just after I entered the cabin area. At first I thought it was a small coyote, but when I shined a light on it, it turned out to be a large fox. I ran past me and disappeared between some of the cabins nearer the Lodge. Now, if only it would harvest a few of the squirrels that insist upon coming in the cabin when the door is open.

Got up at dawn expecting to confirm that Grand had erupted recently, and that was the case. Based on the empty vents and lack of activity, I put the eruption around 05:00. I also noticed that Castle was having a deep, rumbling steam phase, also indicating that there had been a major eruption much earlier. Sawmill was also in eruption, but Spasmodic had a wet runoff channel, and looked it was near overflow again, but I didn't stay to see if that would happen.

The wait for the midday Grand eruption was relatively short. Saw Turban in eruption, and the next eruption was about 33 minutes later, so definitely a Turban Delay interval. Shortly after, a bison wandered across Grand's runoff channels, headed toward Economic. The One Burst Grand eruption came four Turban eruption intervals later.

Afterwards, noticed that Uncertain was having occasional splashes while Sawmill was low. The latter slowly rose over the next half hour, and the splashing in Uncertain decreased, until Sawmill finally did erupt.

Once again, arrived to a Turban Delay Interval. This time saw the preceeding eruption from the bike rack, and there was a small boop that resulted in and immediate drop in Grand's pool level. On the third Turban eruption there was strong overflow, and the subsequent Turban eruption had no overflow, but it lasted far too short to be a true Delay. Then on the fifth interval, Grand had another Turban Delay, just over the limit. The One Burst Grand eruption was just visible in the twilight. Toward the end of the eruption, there were several slowdowns that behaved like Grand was trying to pause.

Another day of Grand erupting in the morning at about the same time I my alarm went off so I could head out to see an eruption. Then again, correlation isn't always causation.

And Beehive erupted a few hours later. Once again, it was calm until shortly before the eruption when the wind started shifting about. Had to use the umbrella.

Before the next Grand eruption Uncertain looked promising, with Sawmill low, but slowly rising. Then Sawmill had two bursts, as if an eruption was starting, neither of which got much higher than the crater rim. That seemed to kill any chance of Uncertain, and the acual stort of Sawmill a few minutes later meant it was time to head over to Grand.

Also had to use the umbrella at Grand. After another series of non-descript Turban eruptions and intervals, Grand had a One Burst Eruption in what seemed like calm conditions. So much so that the people down by West Triplet and Rift got wet. Then the wind started swirling around, and the benches at the main runoff channel got soaked too. Then back to the south.

The next Grand wait started at sunset. For once the interval was not atrocious, and the conditions were much better than last night. The One Burst Grand eruption was well illuminated, and the rain fell in the usual location to the northwest.

It was a windy, cool morning. The temperature was only 50F, but the wind made up for it. The wind also blew the water column from Beehive right at most of the railing.

Once again, just missed a Grand eruption at dawn. I was a bit surprised that there would be two short intervals following yesterday's long wait. The wait for the mid-day Grand eruption wasn't so bad, just under 7-1/2 hours.

That eruption started out fairly normal, but with a lot happening in a short period of time. From Vent Overflow to Boops to Turban Start to Grand Start took twelve seconds. That first burst lasted only 7m18s, which either meant we got to see the shorted Grand in years, or were going to get a second burst. That second burst lasted exactly 75 seconds, just enough to qualify for a "*" marker. The last 30 seconds consisted of Grand trying to stop, but instead boiling up in Big Sawmill Mode. With the total duration at that point under nine minutes, again not surprised when we got a third burst. There was no attempt at a fourth, and Vent & Turban shut off within half a minute.

While waiting for Grand, I noticed a small sput to the south/right of Sput D. At first I thought it was activity from Sputnik, but after getting closer, determined that it was Sput G, which I first noticed about this time last year.

After Grand I noticed that West Triplet was full. About nine minutes after Vent & Turban quit it started to overflow. After about two minutes, with water pouring out, thumps started, and collapsing bubbles could be seen down in the vent. This lasted for about a minute and a half, with overflow stopping shortly after.

Woke up to find that Grand had erupted about a half hour earlier. Not too disappointed, as it was cold and foggy out even after sunrise. Then we got the morning Beehive Indicator call. Went out with the intention of getting a video. The fog pretty much lifted during the wait for Beehive.

Little Squirt was in eruption, so after Beehive's eruption I got a few minutes of it. During that time it slowed down and almost quit. Since it was calm and Geyser Hill was empty, I stayed on to get about a half hour of Anemone erupting. During that time Little Squirt finally did quit. As for Anemone, I got some short South eruptions, and a long one, as well as several North eruptions. It was interesting how North Anemone would wait until noisy people were nearby before finally erupting.

Back in the cabin, I heard over the NPS radio that the Great Fountain prediction was for 11:15, but it was in overflow. This was around 08:45. I guess that this person didn't understand that a prediction based on overflow superseded the one based on the previous eruption. In any case, made the immediate decision to head out and try to see Great Fountain. It was my first visit to the Lower Basin this trip.

We arrived and had maybe a five minute wait. The first series had several nice bursts, which I got on video, so it was a slightly better than Adequate Fountain. Then went over to Fountain Paint Pots on the off chance that Fountain might also erupt. After an hour, we gave up and returned. Fountain didn't erupt until several hours later.

About an hour after the morning Grand eruption, Rift was reported to be in eruption. Went out to Grand at about the 6-1/2 hour mark, and Rift was still in eruption. We just missed a Turban Delay Interval, and proceeded to wait several hours until Grand finally had its One Burst Eruption. Toward the end of that time, Turban was having eruption durations less than three minutes long, and intervals under 16 minutes long. It also had a pseudo-delay, where the Turban interval suddenly jumped by about six minutes, and was followed by a Turban interval with no overflow. During the wait we also saw a nice Oblong eruption, one much larger than the ones I've seen earlier this trip.

It rained overnight, so not going out for the middle of the night Grand eruption was the proper decision. Woke up around the 14 hour mark, so a good time to see what was going on. It was still heavy overcast, and rain seemed likely. As it turned out, I got there in time for a Turban Delay interval. Rumor has it that the NPS recorded an eruption time of around 02:00, so that meant it was the early Delay interval.

For the third Turban interval later, there was again heavy overflow that looked like it was leading up to a Turban Delay. The expected rain never materialized, it was mostly clear and warming. Grand had an explosive start, nicely backlit by the sun. The total duration of the two burst eruption was just over ten minutes, and Vent & Turban quit suddenly, as if the eruption had been a lot longer. It was hard to tell, because the runoff was wet by the rains, but it appears West Triplet never came close to overflowing.

Later it was again time for Grand. Castle erupted just before I left the cabin, and was going into a nice steam phase by the time I got out there. The wait for the One Burst Grand was short, as was the eruption itself.

After sunset it was cold and a bit windy. Arrived at Grand at the six hour mark with the expectation that the string of short intervals wouldn't last. The interval for the next One Burst Grand eruption was just over eight hours, and the duration was under ten minutes.

Grand was not observed during the night, and at twelve hours since the last known eruption, it was time to head back. Once again, I was passing Sawmill when the eruption started. When the first burst ended at less than eight minutes, I was assuming at least another burst. And there was just that one burst, with the total eruption duration just over nine minutes.

Beehive also did not erupt overnight, so went to Geyser Hill for a wait. At first it was cool and overcast, then the clouds disappeared and it became windy. When the Indicator did start, it was time to move to avoid the potential downpour. Based on the top of the Inn flags, it was going to be safe along the southern end of the railing, and it was. The eruption started with an explosive burst, then quit for a moment, only to rocket back up. The duration was a bit short, perhaps due to all that preliminary slopping around.

Went back out to Grand at the six hour mark, expecting this to be the longer interval. And it was, just under eight hours long. The Turban eruption prior to the Grand eruption was unusually short, just over 2-1/2 minutes. At the eight minute mark, Grand's pool looked full, and it slowly kept looking better until the eruption.

This time we had a first burst that lasted longer than the morning eruption, followed by a minute long pause and another minute long second burst. By the end of that burst, Vent was roaring away, but Grand's vent did have water in it for about 15 seconds. During the eruption West Triplet overflowed enough that the wet runoff channel extended all the way to the boardwalk and joined up with the Grand runoff.

As I was leaving, I saw that water in the vent of Uncertain was visible, gently rising and falling. It was drop out of sight for a while, then come back. Occasionally there was a blip, but it was mostly quiet. Finally after about twelve minutes, the water rose to overflow, and an eruption commenced.

Since the interval for Beehive was already over 14 hours, decided to spend an hour on Geyser Hill just in case it decided to erupt. Left after an hour.

After last night, decided that I needed to continue to try to be out for a Grand eruption at six hours into the interval. Didn't need to do that, as the One Burst Grand eruption came just under the nine hour mark for the interval.

Had just left the cabin for the Snowlodge to do some laundry and hadn't left the cabin area when I heard the "five minute" call for Beehive's Indicator. I'd have heard the call for the start if I'd taken the radio with me to the indoor plumbing. With the Beehive interval already approaching 22 hours, I was thinking that it might be a short indicator, but instead it was well over 25 minutes long.

In the evening the weather was not particularly pleasant. It was gray and overcast with a strong wind. At one point everyone waiting dug out their raingear as there were some droplets and the sky looked like it could get much wetter, but the rain didn't ever come. Fortunately only had to wait an hour for the One Burst Grand eruption. The start was explosive, with the first jet of water about 10 meters high, with no preliminary warning. The eruption itself lasted under 8-1/2 minutes, one of the shortest eruptions of Grand I've seen. There was no attempt at Grand's vent even trying to refill.
