A moonlight Beehive eruption in the early morning, except the moon was hidden by some clouds. Along with the lights from the Inn, there was still enough to see it, so that it didn't need to be lit up.

While passing by Sulphide on the way back we caught a smell I've never encountered in this area before, that of a skunk. Didn't notice it on the way out, and was localized to just that area.

A few hours later, in the time it took to go into the Lodge and check out from our cabin, two ravens managed to open the pocket on my bike handlebars and empty the contents out onto the pavement.

By getting out at the eight hour mark, only ended up waiting for Grand for an hour. It was cold and clear, so the moon was bright. The One Burst Grand eruption was short enough that it could've had a second burst, but the slowing down during the final minute seemed like an indication that once it ended, Grand wasn't going to restart.

Beehive erupted just before the start of the Grand eruption window, so many were able to see both eruptions. Ended up waiting for about 1-1/2 hours before the start of a West Triplet eruption, then we needed to wait until West Triplet was nearing the end of its eruption before we got another One Burst Grand eruption.

This eruption had a definite false pause around the nine minute mark before its sudden resumption of activity for another 1-1/3 minutes. West Triplet quit at about the same time as Grand, and Rift still hasn't made an appearance in several days.

It was after sunset, but still light, as I headed out for the next Grand eruption. As I approached the signboards and junction by the lift station, I noticed three deer right next to the bike trail. One ran across the trail into the trees, while the other two stared at me for a few moments, then went bounding off into the meadow toward Old Faithful and Geyser Hill.

I had just tied down my bike at the bikerack near Castle, and was walking toward Crested Pool when Castle started to erupt. It being a windy day, I quickly went the rest of the way toward Tilt to watch what turned out to be the second major eruption of the day. By that time I'd already seen that Rift was in eruption.

Rift erupted for another hour. Two Turban eruption intervals after Rift had quit, Turban had a strong, but short eruption. The next interval was short, and there was little overflow from Grand. So it wasn't a total surprise when the next Turban eruption started strongly. Others waiting for Grand were illuminating it, and I could see at least one boop before the One Burst Grand eruption started. Once again, we got an eruption lasting less than ten minutes with no attempt at a second burst.

The Beehive's Indicator call came in about an hour before the time the alarm was set. It was hours before dawn, so nicely backlit by the almost full moon.

Took a short nap, then went out for a 2-1/2 hour wait for a One Burst Grand Eruption. At first it was dark and mostly clear, with the moon a couple of hours from setting. As it got lighter, the fog formed so that by the time Grand finally did erupt, it was not possible to see into the Sawmill Group from the trees by Rift. Uncertain erupted, and I couldn't tell that until I got closer.

A bit later headed out with the intention of waiting for Oblong. The large steamcloud I saw while riding past the Lodge said that we were a bit late. So instead went Fan & Mortar to see what it wasn't doing.

As I arrived, Bottom was erupting, and Fan's High and Gold vents had high water levels and were erupting vigorously. That activity died down, and over the next couple of hours, there were a series of more ordinary cycles which were never really strong.

Just as about to leave came a radio call about some interesting activity by East Sentinel. The boiling was quite strong, and cyclic. Every fifteen to twenty minutes, the right side would increase in activity and pour water over the side nearest to us. Occasionally the left side would show some activity, but only briefly. It looks like East Sentinel needs to be watched for an eruption.

By then it was time to return to Grand. On the way back, Rocket had a major eruption start just as I rode up. Shortly after, the guy dumping boardwalk pieces fired up his powered wheelbarrow, providing an unwelcome amount of noise. Rather than put up with it, I left.

Arrived at the Grand Group with West Triplet in eruption. Grand spent the next two hours never trying to erupt. Then we got a Turban Delay interval, and four more Turban eruption intervals later Grand finally appeared ready to erupt.

It was a slow start with almost a minute between the start of Turban and the start of Grand. It was a pleasant surprise when the first burst ended at 7m20s. I had just been joking about how we never seemed to get short first bursts any more.

The pause was pretty normal, and Grand didn't play around too much prior to the second burst. That burst wasn't long, and after it quit, it seemed like Grand was sloshing more than normal, with jets of water coming from the vent, when suddenly the pool drained. The eruption lasted less than nine minutes. West Triplet started just before the second burst started.

Even with the short eruption duration, Grand didn't seem to have any afterplay.

Did not stick around for the end of West Triplet, or a start of Rift as it was pointed out that this was an ideal time for an eruption of Great Fountain. So left quickly, and when we got over to the cabin to load up the bikes, learned that overflow had started about a half hour prior. So we had plenty of time to drive out and bike over.

The sun was about to set, and it was below the horizon when Great Fountain finally did erupt. But it was still well lit, and after a few preliminary surges, we got a huge burst that sent out multiple waves across the terrace. Not a superburst, but still impressive, and it all showed up nicely in the recording I made. Didn't stick around much longer, as no one wanted to deal with biking back in the dark.

On the drive back, I did get to encounter just over the Biscuit Basin bridge an oncoming van that just had to get in front of someone else even though I was coming right at him. At least I didn't have to deal with any bison on the road.

In the cabin area, the elk continue to bugle off in the distance to the south.

The moon was nearly full, but the sky and view seemed off, thanks to the considerable smoke still in the air. Shadows were faint and indistinct, and filled in from light scatter by the smoke.

With Grand having erupted during Rift the previous evening, it was hoped that this next Grand eruption interval would be shorter than average. Instead, several Turban eruption intervals after arrival there was a longer Turban interval. It wasn't long enough to be considered a formal Delay, but it felt much like one. Afterwards, the next Turban eruption was accompanied by no runoff from Grand, also typical of a Delay type eruption.

During the wait, I kept checking the weather radar map, because there was a small patch of showers that first appeared over Jackson Lake, and was slowly moving north. Every time I looked, it seemed like it was about an hour away.

So it took Grand five Turban eruption intervals to finally have its One Burst Eruption.. Turban started well before Grand. By that time the clouds had started to move in, so the moonlight, combined with steam from the water column in windless conditions, made viewing difficult. No chance for moonbows.

Some point after we returned to the cabin, the showers finally came through, as everything was wet when awakened by the call that Beehive's Indicator was erupting. Didn't have enough time to make it out of the cabin area before the Beehive eruption started.

Thanks to the longer intervals, Grand was finally going to have an eruption wait starting at a new time of day. West Triplet was in eruption, quitting without a Rift eruption. As it ended, Grand had a long Turban Delay interval. Three Turban eruptions later, we got another long wait as the pool slowly filled, but never started pulsations until the last minute.

Even after Turban started, it seemed Grand was reluctant to erupt. The Vent overflow was well after Turban started, and then Grand had at least 15 seconds of Boops before finally erupting. The first burst lasted well under nine minutes, and there was a short pause. Then the second burst lasted almost two minutes. After the eruption, it took Vent & Turban, which quit, about twenty minutes to restart.

Went out for Grand's first overflow, which was relatively short at 4h17m. Once again, this took place during an eruption of West Triplet and a Turban Delay interval.

Made it back to the cabin just ahead of the first thunderstorm. The second one featured raisin sized hail that turned the area white, along with at least one lightning strike nearby, as I saw now flash but heard what sounded like a gunshot.

The rains continued up to the time to head back out for the next Grand eruption, and I decided I'd rather not get wet for a One Burst Eruption, or even a two burst eruption.

With intervals averaging around eight hours, Grand has locked itself into erupting around the same time of day, every day. Right now that means just before dawn, middle of the day, and just after dark. This morning, I was fully dressed and about to head out the door when I saw that the webcam was reporting Grand in eruption. So time to undress and get a couple more hours of sleep.

Went over to Geyser Hill to try and get some video recordings. Did get another eruption of Slot, and could have gotten a Lion initial if I had been paying attention. With the huge crowd forming after the start of Beehive's Indicator, I decided to try and do a video from Sponge. With the smokey haze creating a white background for the white eruption column, it's probably not the greatest.

Early afternoon it was time again for the mid-day Grand eruption. Which turned into the late afternoon Grand eruption.

I got out to the Grand Group with West Triplet in eruption. When that ended without an eruption of Rift, I figured we had a bit of a wait until the next West Triplet eruption. That took place over three hours later, after a long series of quick fills by Grand, followed by low pool waves and short Turban eruption intervals and durations.

During the wait we also got to see a Castle minor eruption and three Daisy eruptions.

West Triplet finally erupted again, with no real change in Grand's behavior. Finally Rift started to erupt, and then we got the One Burst Grand eruption another two Turban eruptions after that. The eruption lasted almost exactly ten minutes, but at least Vent & Turban continued.

The string of One Burst Grand eruptions continued today.

First it was the one before dawn, which consisted of a series of short Turban eruption intervals before a short One Burst Grand eruption.

Then there was the One Burst Grand eruption that had a shorter series, but also had short Turban eruption intervals. This time Turban initiated the eruption, and it lasted over 11-1/2 minutes. West Triplet also started erupting just over a minute after Grand started. And once again, there was some large afterplay from Grand starting about five minutes after the restart. Disappointed that we didn't get the Rift eruption over with.

Just after dinner came the call for Beehive. During the walk over, also heard that Depression was starting to erupt, so I managed to capture that to video.

At the seven hour mark, Rift was in eruption, and had been so for quite a while. Only 45 minutes into the wait, Castle started to erupt, and it quickly became obvious that it was going to be a major eruption. A number of those waiting were going to go over there to look for moonbows, with Rift still in eruption. But on the next Turban eruption opportunity, it also became obvious that Grand was going to start, based on the strong Turban eruption.

There was a nice, short first burst, a fairly lot pause, and a short second burst. It was dead calm, and the jets of water rose above the building steam cloud. But once again, we got a two burst eruption lasting less than ten minutes, with Vent & Turban then quitting.

Castle was still in eruption, and had pretty much made the transition to steam, but was still impressive seen from the boardwalk, and there was enough spray to see a nice moonbow.

Another morning wait for Grand with the previous eruption time in doubt. But only a 1-1/2 hour wait before the One Burst Grand eruption, and did get to see from Sawmill the Beehive eruption. The start of Grand's eruption was one of those where the pool is nice and high early, and never drops or does something annoying.

West Triplet started at about the time it became apparant that this was going to be a long eruption. I waited for the end of that eruption intending to record the start of Rift's eruption, but for once I was disappointed that Rift did not erupt.

Afterwards realized that it had been an hour since the last report of an eruption of Tilt, so waited about ten minutes to record the next eruption. At least I didn't wait an hour there like the last attempt.

Went out to Grand prepared for a stay into the dark, and needed what I took out. First, West Triplet was in eruption as I arrived, and when it ended without a Grand or Rift eruption, I figured we had a few hour wait until the next West Triplet eruption.

During the wait, Grand had several early fills but then dropped. West Triplet finally erupted over three hours later, and the very next Turban eruption was a Delay eruption interval. Then 45 minutes later Rift started. Fortunately, Grand was able to have the One Burst Eruption two Turban eruption intervals later. The moon was brown, so the view wasn't great.

It was pointed out that the missing GeyserTimes Grand info could be because it was never entered in the first place. That would seem to be the case, as there are a few non-electronic records during those years. But the electronic times never duplicate the observed times. That implies that the electronic records are incomplete. In any case, I are confused, and maybe what is going on with the electronic records needs to be clarified.

After last night, not in a great hurry to get out and about. Did end up getting out to Grand Group around the seven hour mark. An hour later it was warmer and drying and we got a nice One Burst Grand. No West Triplet eruption before or after.

In the Sawmill Group Uncertain was splashing and slopping out water, so it wasn't a long wait before we got an eruption there. Did not seem to be as tall as the one I saw yesterday from Grand.

Oblong hadn't been seen this morning, so worth a trip down that way. Economic was in slight overflow, although it is getting oranger. Got to Oblong, and barely had enough time to set up the camera before the eruption began.

About that time came a call that water was splashing in Fan's Main Vent. Got down there and there were still a number of huge splashes seen. Mortar's Bottom vent was also in eruption when Gold and High vent had abrupt starts. High was especially impressive, and if later in the cycle, would have been a really good sign. Instead the activity slowly decreased. But it is encouraging that Fan & Mortar are exhibiting more than short, weak cycles.

From there, it was noted that it had been over a day since an eruption of Artemisia had been seen. A quick side trip showed that East Sentinel was boiling heavily, but there was no sign of any recent eruption. At Artemisia there was first a short wait before an Atomizer minor eruption, then almost immediately Artemisia started. The wind was ideal the entire eruption, with the steam going into the trees and no one having to move to avoid the steam bath.

On the way back, attempted to see a Rocket Major eruption, but instead got Grotto quitting. The dumpster makes for a nice view block for a number of the benches which by then were in the shade.

Just got back to the cabin after having a burger at the Lower Store when suddenly Beehive's Indicator started. So it was back out to Geyser Hill. Little Squirt may have started erupting during Beehive's eruption, because I don't remember seeing it when walking out, and the water was just starting to progress down one runoff channel.

Got out to Grand in time for a Castle minor eruption. Then waited an hour for West Triplet to start. This time Grand had the One Burst Eruption on the next Turban eruption. It was short in height, but long in duration.

Since the wait for Grand was shorter than expected, some of us went down to Oblong to see if we could catch another eruption. Waited until well after sunset, but despite some strong overflows, it did not erupt.

In the predawn hour, just outside my cabin, I encountered a deer as I was headed toward the indoor plumbing. It was still there, but took off, as I returned.

Went out to check on Grand next, and found that it had erupted as I was getting prepared to go out. I did see a steamy runoff channel from Rift, indicating that it had quit during or just after the Grand eruption.

Back to the cabin, where it was time to make a quick sandwich for breakfast. Just as I put the jelly on the bread, get a radio call for Beehive's Indicator in eruption. The sun was low and it was calm, with a nice rainbow at the top of the water column and in the rainfall.

It was during Beehive's eruption that another radio call came through. This time it Fan & Mortar were finally having an observed event cycle, with Main Vent splashing and Bottom Vent erupting. So after returning to the cabin, got on the bike and headed on down. Nothing much came of it, but it's nice to see something happening there.

The afternoon eruption was really a wait for West Triplet to erupt. The Turban eruption intervals were fairly short, and it wasn't until West Triplet erupted that Grand showed that it might erupt, by having the Turban intervals get shorter. The One Burst Grand eruption took place on the Turban eruption immediately after the end of the West Triplet eruption. The start was nearly simultaneous, with Grand having a boop, then Turban, then the Grand start, all within a couple of seconds. The eruption itself was long, almost 12-1/2 minutes long.

Back out to Grand in the dark, but with a nice moon until well after midnight. An hour after arrival West Triplet started, triggering Rift to start just before midnight. Waited a few more Turban eruption intervals, then as the moon was setting, decided to give up and head in.

Had just approached the bike rack at Castle when we heard the radio call for Beehive's Indicator. So bicycled back to the cabin and headed for Geyser Hill. The moon had set, so the bright lights were on. I was at Anemone when it started. Was quite impressive.

Returning from Geyser Hill we saw a large steamcloud to the north. Grand was erupting.

Back at the cabin, headed to the indoor plumbing and in the light from the streelight I saw a head poking up from behind the rocks along the drive. Was being watched by a deer just downslope from the road. Leaving the restrooms I was surprised by a second deer running out from the cabin area, across the road and running down the hillside. The first deer on the slope was still there, watching me. Then it moved away and I lost sight of it.

I want to get a video of Tilt from the start, as part of my project to document all sorts of features. The best way to get a full eruption of any geyser is to start recording well before there's any indication of an eruption. So I spent an hour out there, with nothing happening. Finally Tilt starts to steam heavily and splashing begins. And that's when the battery finally runs out. I had checked just a minute or so before, and it still read 10%, so that last tenth goes quickly. Noted for the future. And I still need a full Tilt eruption.

After that fiasco, it was time to head to Grand. Not sure if Rift erupted overnight. It was two hours of non-descript Turban eruptions, again. Grand then finally looked good around the 20 minute mark, and kept on slowly filling and started to have waves. This process was so slow that Grand ended up having a Turban Delay for the One Burst Eruption. It lasted just under ten minutes, just before the end West Triplet began erupting.

Beehive's Indicator was called just as Grand started. The bench behind me, which had been full, was empty by the time Vent started.

After Grand I stuck around to get the duration on West Triplet, to see if Rift would start, and also to observe if there was afterplay. There wasn't any afterplay other than a few weak splashes just about the time West Triplet ended, a half hour later. Rift did not erupt.

Back out at sunset for another West Triplet eruption. And once again, no Rift eruption. I thought that would be a good sign, but instead ended up waiting almost three hours before getting the One Burst Grand eruption. And West Triplet was not erupting when finally left the area.

During the wait Castle had another minor eruption.

So this afternoon, shortly after Rift failed to give me its blessing, as I'm leaving the area, I notice a host of GeyserTimes note entries for several features in the Sawmill group, each with cutesy commentary. The last one for Spasmodic is one word: "Chunked".

I have no idea what this is supposed to mean, and I've been observing the Sawmill Group for decades. So I post a flag on the entry, "what does "chunk" signify?" Is it supposed to be a noun, verb, adjective, or some other meaning?

The poster, "Craigmon99", instead of clarifying the observation, amends the comment to say, "Chunk! The feature that is known as Chunk near Spasmodic was overflowing HKoenig… are you familiar? :)"

It seems "Chunk" is what was years ago called Spasmodic's Triangle Vent. For years it had a small rock wedged into it, and no attempt was made at removal because the most likely outcome would have pushed it deeper. It disappeared one year. It was also one of the vents that was vandalized when someone went around dumping purple dye into some features in May 2020.

In any case, the owners of GeyserTimes don't like "interpersonal drama", so this insult has been swept into the Memory Hole. I want to preserve it here. And it was an insult, as too many newcomers are treating GeyserTimes as their personal High School Cafeteria where Kool Kidz hang out and insult the nerds and geeks.

Related, I've also learned recently that for a number of years all the Grand observations: codes, durations and comments, etc., have been deleted in favor of electronic download records. I checked, and that's the case from 1999 through 2001.

I knew that Grand had erupted with Rift still erupting, so figured the interval would be on the long side. Got out there around the eight hour mark and ended up waiting another 2-1/2 hours before we finally got the Grand eruption. Because of that, there wasn't the earlier fog and steam, making for a nicely backlit eruption.

Grand took it's time getting going after Turban started. It quit quite abruptly, a good sign, and we got a second burst. The eruption was so short that we could have easily gotten a third burst, but through the steam we could see no attempt for the pool to refill.

I went out later for Grand's first overflow, and it came very close around the 4h30m mark, but didn't quite make it. It was another Turban eruption interval later, a longish 4h50m, consistent with other first overflow times I've observed the last couple of weeks.

Got out to Grand in the last afternoon expecting too see West Triplet and the Rift erupting. I was mostly disappointed. Instead we got a series of shortening eruption intervals from Turban, ending with an early fill on Grand and a short Turban eruption interval.

Then Grand took nearly two minutes to start. At the beginning, the pool looked like it needed to fill more, and it did, then the waves started, and got increasingly stronger. Well past the minute mark Grand had strong convection over the vent, then boiling, then some booping, and finally the eruption started.

The length of the first burst was more typical of a One Burst Eruption, but we did get our second burst. Considering the length of the first burst, this time I did not expect any attempt at a third.

Of course Vent & Turban quit. West Triplet started erupting shortly thereafter, so I stuck around to see if it would trigger Rift. It didn't, but A few minutes after the Vent & Turban restart, Grand started having fairly good after play. Some of the burst were thick and five to seven meters high. Something to consider when there is a Continue instead of a Quit is to stick around and see what the afterplay is like. An afterburst is most unlikely, but even and attempt would be welcome.

Finally, just after dinner and well after sunset we got an eruption of Beehive while it was still light enough to not need any artificial lighting.

There was thick fog in the morning when I went out to Grand. Not surprised to find Grand full and overflowing. About an hour later, it was still foggy when West Triplet started. The steam over Rift intensified, and we ended up getting a an eruption. Right after Rift started, Turban had a Turban Delay interval.

Five Turban eruptions later Rift ended and we got a second Turban Delay interval. By then, the fog was finally clearing, so we had a nice, clear view of the One Burst Grand eruption four more Turban eruption intervals later.

Shortly after Beehive's Indicator started. Was unable to get to Geyser Hill because there was a bison standing on the mound behind Sulphide Spring, and an NPS volunteer harassing people who wanted to use the boardwalk.

In the evening got out to Grand in time for a West Triplet eruption. During that eruption, Castle had a minor eruption. Grand waited until after West Triplet ended before having another One Burst Eruption.

Not much rain overnight, but the radar map said more was coming.

I got out to West Triplet at dawn and expected Rift to start. It steamed heavily until West Triplet quit, then quieted down. By then the rains had pretty much paused.

Two hours later we got the One Burst Grand eruption just as the rains restarted. It was so foggy and steamy I could see the start of either Turban or Vent.

West Triplet started just after Grand ended. I stuck around in the rain because I was pretty certain that Rift would follow, and it did. Just before Rift started I also realized that Castle had started too. Turned out to be another major eruption, of which there have been quite a few (relatively speaking) the last few days.

All afternoon the weather radar map looked like the current rain would be the last, but every time a new shower would build and slowly move through. That was the case in mid afternoon, and not only did the rain start with the Indicator call, the wind picked up too, so Beehive had a short, gray-on-gray eruption. (So not surprising that no geyser gamer even tried to make the claim that it was the greatest Beehive eruption anyone has ever seen. At least so far.)

I then took advantage of a lull in the rain (it didn't stop completely) to head out to Grand. Fortunate timing, as the Turban preceding the One Burst eruption started just as dropped my pack beside the bench. Another steamy start to an eruption. Starting around the 8-1/2 minute mark Grand started slowing down like it was going to quit, only to pick back up. That continued for the rest of the over twelve minute long eruption.

Have been keeping a log of interesting radio calls, and intend to post a summary at the end of the month. But here's a typical example: Visitor assist at Riverside. Woman at the Dan Wenk Memorial Vault needs assistance as she has dropped her iPhone into the pit. (They are supposed to be water-resistant…)

It was raining in the morning, and the forecast was for rain all day. So didn't get out into the Upper Basin until after noon when it was time to head out to Grand.

The wait wasn't too bad, only 1-1/2 hours, and we got another two burst eruption. This time the pause between the two bursts was short, but so was the total duration for the eruption. Despite that duration being well under ten minutes, Vent & Turban quit. With the rain reduced to just drizzle, didn't stick around any longer.

A while later had prepared dinner and was just starting to eat it when a call for Beehive's Indicator came over the radio. It was already in eruption, but was caught early so there was plenty of time to get over to Geyser Hill.

With the rains supposed to be continuing overnight, that was it for the day.

It was a quiet morning, with nothing much going on. Did go down basin to record an eruption of Daisy. Was calm but smoky and Daisy appeared completely normal.

Went out to Grand just in time to catch the Turban delay interval. The next Turban eruption had no overflow from Grand. Four more, and we finally got heavy runoff.

We also got a second burst. As with the other two burst eruptions the last few days, there was almost a minute's worth of sloshing around. Following the second, no attempt at filling for a third, and Vent & Turban even continued to erupt.

That was when Castle also started to erupt. Because of the walkway closure north of Grand, the crowd at Grand all got funneled right into the crowd waiting for Castle, so the walkway was packed. Except the stretch of boardwalk getting wet from Castle's spray. This was another major eruption in a row by Castle.

Another Grand first overflow took place at around the expected time, but once again, it was also during a long Turban Delay eruption interval. Seems to be a pattern here.

With the shorter first overflow, got out to Grand around the seven hour mark. A Turban eruption Interval later West Triplet started. Based on the intervals, expected to see Rift about a half hour later, but West Triplet ended after about 35 minutes. It was only a couple of Turban eruption intervals after that before Grand erupted.

Once again, Turban had a short interval, less than 14-1/2 minutes. Then Grand took well over a minute to start erupting. This time the pause between bursts was quick, despite the first burst erupting long enough to be the only burst.

Five minutes into the eruption, Beehive's Indicator started, so of course a number of people had to scurry off to Geyser Hill in a panic despite most indicators lasting long enough to catch the end of Grand and still make over there. Really too bad this wasn't a three burst eruption.

Went out to Grand before midnight expecting to see evidence that Rift had erupted. As I approached Crystal, I could hear Slurp slurping away. Which happens when Crystal is full and flowing into Slurp. Belgian was also quite high, and West Triplet was empty and dry.

Had to wait about 1-1/2 hours of non-descript Turban eruptions before a Turban eruption that was noticeably stronger and louder. This activity continued on for nearly 1-1/2 minutes before the Grand eruption finally started.

It was a long burst, and easily been a One Burst Eruption, but after almost a minute, got a nice second burst. If this burst had lasted a bit longer, the eruption would've earned it's "*".

Went back out in the cool morning about 7-1/2 hours later. Once again there was a series of uninspired Turban eruptions. Then we had a short Turban eruption interval, followed by a second one where Grand started having a full pool with strong waves around the 13 minute mark. It took Grand over two minutes of strong pulsations and heavy upwelling before it finally had the first boop, nd even then took a few seconds to get started.

Again, that burst ended with a duration that could have easily been a One Burst Eruption, but almost immediately Grand's vent refilled, and again it sloshed around for what seemed like a long time before the second burst started. It was dead calm, and the water column was extremely high.

During the eruption, West Triplet started to erupt. I figured that this would probably be the eruption that triggered Rift to erupt, so stuck around to at least get the length of the West Triplet eruption.

It took Rift 45 minutes from the start of West Triplet to finally make an appearance. The West Triplet eruption itself lasted about 1h13m, which is one of the longer eruptions that I can remember.

The walkway is blocked off just north of Turban again for the boardwalk construction, so there were a lot of people going as far as Grand's sign and heading back. At one point when the area had emptied out, I noticed a woman hanging around the northern runoff channel. With no one around, she got out a spoon and her phone/camera, dipped the spoon into the runoff and then did a selfie recording while sipping from the spoon. She repeated this action from the West Triplet runoff channel. As she passed me at Rift, I casually mentioned that randomly sampling thermal runoff was not the best thing to be doing, as some waters can be pretty nasty. She shrugged it off with a no-spika-da-Englis attitude. I'll let someone else do the YouTube, Instagram, or TikTok video searches.

Went on down to confirm that ignoring Fan & Mortar this trip has been the right decision. Spent an hour there and saw garbage mode. On the way back, I noticed that Rift was quiet 1h45m after it had started.

Went out for another Grand 1st overflow time, expecting to wait a while. Once again, Crystal and Belgian and high, with the first almost to overflow. The first overflow took only 4h31m, but came during another Turban Delay interval. It's almost like Rift had no effect on Grand this time.

The next Grand eruption tended to support that hypothesis. Was originally planning to head out later, but decided to come out instead at around the 7h15m mark. Waited three normal Turban eruption intervals and then Grand had an early fill with heavy waves and finally the One Burst Grand eruption, which lasted one second over ten minutes. It was followed by an eruption of West Triplet, which seems like a quick recovery for it, too.
