Month: June 2025

Grand is starting to get stuck in a mode where it erupts almost exactly three times a day, eight hours apart. Once again went out for the first eruption of the day just before sunrise. At least today there wasn't any ice on the boardwalks.

Castle was still putting out some noise at the end of a steamphase. Despite it being well over seven hours, Grand still hadn't erupted, thanks to the Rift eruption last night.

Only waited two quick Turban eruption intervals before the One Burst Grand eruption started. It lasted only 9-1/2 minutes and should've had another burst. What little breeze there was pushed the misty rain over the boardwalk from West Triplet on north.

Afterwards, I noticed that Uncertain was splashing and gurgling heavily. A short wait gave me a short Sawmill eruption where the starting water level was out of sight. As soon as it ended, Uncertain started to overflow and burst up. It took a while for those burst to build in height to a full, normal eruption.

For the wait for the mid-day Grand eruption the Turban eruption intervals varied greatly, from over 22 minutes to barely over 16. Then West Triplet started to erupt and Grand followed before West Triplet ended. The first burst only had about ten seconds of Big Sawmill before Grand paused. The second burst lasted nearly a minute, and an eruption lasting just over ten minutes had Vent & Turban quitting.

Before sunset Grand had the possibility of erupting before sunset, but it didn't happen. Instead we got a series of non-descript Turban eruptions, then a long West Triplet eruption. Grand did manage to have the One Burst Eruption right after the end of West Triplet. There was still a fair amount of light, and the moon, so it wasn't necessary to illuminate the eruption. It was still fairly warm, and the wind from earlier in the day had disappeared. The only drawback was that during the wait, we were subjected to an obnoxious family that only left two minutes before the Grand eruption.

We also got to see another 3-1/2 minute Castle minor during the wait.

Went out to Grand expecting the next eruption to be in the dark. Did not expect it to be well after midnight.

At around the time I would have expected the eruption we got a strong, heavy overflow from Grand and the Turban eruption interval was 24-1/2 minutes. While not a Delay as defined, Grand and Turban acted as if it was for the rest of the wait. The durations on Turban eruptions got shorter as did the intervals. The final Turban eruption interval preceeding the explosive start of the One Burst Grand eruption was less than 14 minutes, and it took Turban over a minute to finally begin its eruption. The lighting by the moon, and the obscuring steam wasn't too bad, but not bright enough for us to seen any moonbows.

Came back out after dawn, and this time there was no wait for the One Burst Grand eruption. What little air movement was toward the south, although there was a steady rain mist coming down to the northern boardwalk were there was the view.

Checked out Economic before both eruptions. For the first, Economic was low, with the water level inside the inner rim and many of the runoff channels (especially the one under the boardwalk) showed no sign of being wet recently. For the second visit, Economic was in steady overflow and the under boardwalk runoff was wet.

Went down basin to take a look at the progress (or lack thereof) in rebuilding the boardwalk south of Giant. There old walkway has only been partly removed, and from a distance I could not seen any new sections. On the way back, I did manage to get a Rocket major eruption.

Like the morning eruption, we didn't have a long wait for the One Burst Grand eruption. An otherwise undistinguished eruption at midday with weather that was nicely sunny but a bit breezy at times.

After the Grand eruption, West Triplet started to erupt. As a Rift eruption is expected by midday tomorrow, I waited around for the end. It only lasted eight minutes, so no Rift eruption for at least a few more hours. Just before I left, Grand started having some small afterplay.

Was not surprised to see Rift in eruption when I came out for the next Grand eruption. Ended up waiting through a two hour series of Turban eruptions where the durations were short (around 3-1/2 minutes) while the intervals got shorter. Once they got around 16 minutes, I noticed that Rift was dying down. Half hour later, it quit as Grand started to erupt. We got a well lit two burst eruption where the durations were reasonable and ordinary.

Just before Grand, Beehive erupted. I watched it from the Sawmill Group.

---

It seems like every day over the radio I hear at least one report of a "thermal trespass" in the Biscuit Basin closure. I have yet to hear of anyone being cited for entering that closure. All that happens is that some or all of the group gets an identity check and a verbal warning. So if you are willing to risk the possibility of having a lifetime record in the national Dept. Of Interior "DOI-10 Incident Management, Analysis and Reporting System (IMARS)", you can get out there and look around and shoot your videos and selfies.

Plan ahead. Go out in the morning when the fog will help hide you. Go in from the Mystic Falls trailhead. Carry a radio that's tuned to the West Direct and West Repeater channels so you know when you've been spotted. Wear a bit of a disguise, in case you are seen. Something you would normally never wear, like a bright red MAGA ballcap, or a fluorescent orange jacket. Something that could easily be used as identification from a distance, and easily hidden when needed.

If you do get cited, have a lawyer ready so you can file a discrimination lawsuit. Just because you aren't a foreign tourist (frequent culprits) and despite your have spent years visiting this park, that doesn't mean you should not receive a verbal warning like everyone else. Enjoy!

I've been informed that 'coy' is an acronym from wildlife management jargon meaning "cub of year", a term that has escaped into the wild. I guess it's not surprising that a group that seems to enjoy using terms like "stall", or "crash", or "ernesto", or "delay" would readily adopt it.

Arrived at the bike rack by Castle to find Rift in eruption. For the next 2-1/2 hours got a series of short duration and short interval Turban eruptions. When Grand finally did erupt, Rift was still in eruption. The first burst lasted long enough to be a One Burst Eruption, but not long enough to prevent a second burst. It turns out that after a 70 second wait, we were rewarded with an explosive start to a second burst.

Rift quit sometime during Grand's eruption, and Vent & Turban were only off for about six minutes before their restart.

Uncertain looked promising, but while it made a lot of noise gurgling, there wasn't much visible splashing, and after a half hour or so, the vent was mostly quiet.

Then it was time to go over to Geyser Hill to wait for Beehive. Not a long wait, and the wind ended up cooperating. At first it appeared that the railing was going to get inundated, but the wind shifted enough that by the end of the Beehive eruption, the wall of spray was crossing the river and forcing spectators over there to move.

After noon there was a nice short wait for a less than seven hour One Burst Grand eruption interval.

At first I thought the overnight Grand interval was ten hours, and I had no reason to head out. Then I woke up and redid the math, and decided a twelve hour interval was worth investigating.

I expected to walk up to a full pool, and I did. So much for seeing fog rising above the fog on the webcam. In any case, it was a Turban eruption interval later that we got a Delay that lasted over 33 minutes.

A quick check of Economic showed it to be well below overflow, at the level of the inner rim. There also weren't many puddles in the runoff, and the area beyond the boardwalk was dry.

But like last night, there was only a two Turban eruption interval delay, with the explosive Grand start actually visible due to a slight breeze from the north. Grand ended at exactly eight minutes, followed by a half-minute long pause before the second burst. At 1m07s, that burst wasn't long enough to constitute a Long Burst. About 45 seconds after the end of the second burst, it appears through the steam that Grand was full and starting to push out water. That's when the activty of Turban and Vent picked up, with Vent blasting away. No third burst, and a less than ten minute long Grand eruption ended with Vent & Turban quitting.

Decided that since there wasn't much going on, and it was early, that this might be a good time to go to Fountain Paint Pots and maybe seen an eruption, or at least take a look at the vista enhanced overlook.

There were some periodic Jet eruptions after our arrival, and a half hour later Morning's Thief erupted. I always remembered it as being tall and narrow. This eruption was tall and wide, with much overlap of Morning's pool.

Fourteen minutes later Fountain finally erupted, with two more of the wide and tall Morning's Thief eruptions. Fountain lasted only 28-1/2 minutes. I tried to take video of the whole eruption from the first Morning's Thief, but the wind was directly toward the overlook. And it was cold so there was plenty of steam. Now that it actually is an overlook, will have to try again under better conditions.

In the afternoon we watch ten eruptions of Turban before we finally got a One Burst Grand Eruption. Every one of those was similar to the preceeding, the only change was that the intervals between Turban eruptions got shorter. After the sixth Turban eruption, West Triplet started to erupt. This is the first time I've seen West Triplet have a normal erupion lasting about 1/2 hour that wasn't associated with eruptions of Grand or Rift. At least the One Burst Grand eruption lasted over 11 minutes.

After that, it was time to have dinner. And after dinner, Beehive erupted. The wind cooperated and no one on the walkway got wet.

The sky was clear and the moon was beyond the first quarter, with the temperature already in the upper 30s. But only had to wait a couple of Turban eruption intervals before the Grand One Burst Eruption started. Once again, it was a short eruption, at 8m41s, and there was no attempt at a second burst.

Thanks to an observation in the middle of the night, could sleep in a little longer before going out for the morning Grand eruption. The sky was much clearer than expected, but cold and windy. And still ended up waiting two hours. We finally got a two burst eruption from Grand. After the second burst ended at just over nine minutes, I thought a third burst was guaranteed. The vent drained and made no attempt to refill.

It was a day to get some housekeeping chores out of the way, but fortunately the call for Beehive's Indicator came during a lull. Over on Geyser Hill it was still cold and windy, and that wind kept shifting enough to require the deployment of the umbrella on a couple of occasions.

Later, I got to see Rift in eruption as I arrived at the Castle bike rack. West Triplet was drained by the time I arrived. Instead of the long wait, after a half hour Grand had a Turban Delay Interval of just over 30 minutes. With Rift (and Percolator) still erupting, we got a One Burst Grand eruption that lasted 45 seconds longer than the morning's eruption.

After a night where any sort of aurora failed to appear, we were rudely awaken by the radio call for the start of Beehive's Indicator. Made it out in plenty of time, and didn't need the umbrella this time.

Afterwards, not knowing the time of the overnight Grand eruption, I decided to head out at the twelve hour mark. Then I heard another radio report of the bear and cub in the Daisy Group. That quickly changed to near Castle. I decided today would be a good day to be on foot, in case the NPS decided to shut an area down and I ended up separated from my bike.

Got to Grand just in time of the start of Turban. I'd arrived so early that shortly after I was able to see Grand's first overflow, with the water suddenly creeping down the dry runoff channels. That's when I learned that the overnight time had been posted. Seems that First Overflow time hasn't changed much over the years. This one was 4h17m, and I'd always worked off of 4h20m.

At the same time, Belgian and Crystal were both still extremely low.

What was interesting was that the Turban interval following was over 30 minutes long. One hypothesis I've had is that almost every Grand eruption has a Turban Delay Interval, it's just that we don't seem a lot of them because they come between First Overflow and the opening of the eruption window, when people finally start observing Grand.

In any case, I headed on down basin to check out Economic. It was in overflow, but not as strong as what was seen last night. Onward to Giant. The flowers growing in front of Bijou and Catfish are out in force, and a good sign nothing much has happened there.

Then did the loop around Daisy, which had erupted as I approached Oblong. On the boardwalk next to the swamp beyond Splendid, I found a long line of muddy little bear footprints. All the way to the junction.

Being a Monday, I realized that I needed to head back to Grand before the boardwalk construction crew arrived at 10:00. Got back just in time, as the guy putting up the closure signs appeared at Chromatic at 10:10.

On the way back, noticed that Economic seemed unchanged.

The wait for the One Burst Grand eruption only an hour, with no Turban Delay Intervals. It lasted over eleven minutes, and was followed by a six minute pause in Vent & Turban's activity. West Triplet also started thumping and splashing following Grand.

While waiting for Grand, I was surprised to see Uncertain erupt. All of us waiting there saw the narrow water column, but afterwards Uncertain did not exhibit its usual post-eruption gentle steaming. Instead it was splashing as if it hadn't erupted. It had quieted down a bit by the time I left the area after Grand.

Down at Grotto the boardwalk crew swapped out dumpsters. As usual with the NPS, the esthetics of the placement has a lot to be desired.

Then spent 1-1/2 hours at Fan & Mortar watching what appeared to be a real cycle of activity. Started out near the end, with all the vents of Fan erupting weakly. They then stopped for a while, until I notice Bottom Mortar splashing at depth. This got stronger and then Fan's River vent started. Shortly after, High started and looked quite strong-- 2-3 meters high with Gold also joining in strong. That didn't last long, maybe a minute at most, then the activity subsided. When I left, it looked a lot like how it did when I arrived.

A quick check of East Sentinel showed no change in appearance from yesterday.

At Grand there was an hour wait under cold and blustery gray skies for an undistinguished One Burst Eruption that lasted just over nine minutes, which made no attempt at a second burst.

It was almost dark when the radio call for the start of Beehive's Indicator went out. It included a request for a flashlight. It was still bright enough that the water column could be observed, but we lit it up anyhow. Fortunately, despite it being a windy day, there was no wind during Beehive's eruption, with the water column going straight up and the spray dropping straight down. As we left, the wind picked back up.

("Coy"? Or is it spelled "koi"? Obviously some petty apparatchik decided that someone else, at some time in the future, could potentially be offended by calling a newborn bear a "cub" and that needed to be rectified immediately. Renaming well established things is an offensively obnoxious and stupid exercise of raw power, whether it is unilaterally renaming "Mt. Doane" to "First Peoples Mountain", the "Gulf of Mexico" to "Gulf of America", or changing "cub" to "coy". The online dictionaries don't seem to have caught up with this particular neologism, either.)

The local ravens paid us a visit this morning. Suddenly there was all sorts of noise on the roof and in the trees nearby. I found the contents of the pouch on my bike scattered about, and Suzanne's bike seat had a nice hole punched into it.

Even before the Rift eruption I'd decided to sleep in this morning, but with that wakeup call, got out to Grand around the usual time. Waited a few Turban eruption intervals before we got the expected Delay interval. There wasn't any booping, but the strong convection over Grand's vent was clearly visible and doming at times.

Then had to wait the usual seven Turban intervals before Grand finally did erupt. As the eighteen minute mark on that interval approached, Grand did not look good, but it quickly filled so that by 22 minutes, Turban had started and Vent began overflowing. Still, Grand had to have several seconds of booping before finally initiating the eruption. And once again we got our One Burst Grand which lasted less than ten minutes.

Was contemplating going over to Geyser Hill when the Indicator call went out. Got over there just before the eruption, and had to make a decision as to where to go, especially after yesterday's eruption. The wind was strong and shifting all over the boardwalk. Ended up near Plume, and only had to use the umbrella for a few seconds near the end. Like the Grand eruption earlier, the Beehive eruption itself was knocked over by the wind. The length of board walk drenched was down near the sign and benches, and surprisingly narrow.

I noticed that both Belgian Pool and Crystal Springs were both extremely low as I headed over toward Grand.

Waited a couple of Turban eruption intervals before we got the Delay Interval. This one was relatively short at less that 27 minutes, when compared to the ones lasting well over 30 minutes we've had recently. Grand then had a One Burst Eruption just two Turban intervals later, on an interval that tried to become a Delay but came up short by about a minute.

Checked on Economic afterwards. It was strongly overflowing in all directions, with occasional convection. The water to the south reached nearly to Key Spring, while the runoff under the boardwalk extended well into the flats.

Came back out at dawn for the next Grand eruption. The One Burst Grand lasted twelve minutes, and it finally didn't have a Turban Interval delay and erupted with a shorter interval. Otherwise it was just another cold and steamy eruption.

The day was clear and warming rapidly, and there had been no report on Aurum in over a day, so I decided to go there and record an hour or so of video with the hope of catching an eruption. About an hour later we were rewarded with just that, a nice, strong eruption that seemed to last longer than the 1m16s it actually did.

From there stopped by Beehive to kill a little time with little expectation of seeing an eruption, but didn't have to wait long for the Indicator to start. During that time, as the crowd got larger, I was assessing the winds, and trying to figure out the best place to avoid getting wet. My efforts were wrong, as I got drenched and the umbrella when deployed was of little help.

Still damp, headed out to Grand. Once again we got a short interval before the One Burst Grand eruption. At just under 8m10s there was a long false pause, followed by another 2-1/2 minutes of strong activity (not the usual Big Sawmill). Afterwards West Triplet was in heavy overflow with thumps and some small splashes.

That's when Castle started to have a major eruption. Waited and watched that as it turned to steam before heading in.

Later in the afternoon it appears the bears we saw a week ago were back in the area. Heard over the NPS radio that at first they was causing a traffic backup south of Biscuit Basin. Then they were seen headed south toward Punchbowl and Black Sand Basin along the Daisy to Biscuit bike trail.

It was well before sunset, but went out for the next Grand eruption with the expectation of it happening in the dark. The second Turban of the wait not only was a Turban Delay Interval, but had several boops.

While the Delay interval was in progress, a bison appeared over between Rift and the walkway. It just stupidly stood there as only a bison can for at least fifteen minutes. Finally, just before Turban started to erupt, it began to move toward Grand and the hillside. With Turban erupting, it slowly made it way along the base of the hill. The rim of Grand's crater lies right at the base of the big rock. The bison walked in front of the walk, then ignored Turban and proceeded on until it finally encountered the grassy area to the north.

A couple of Turban intervals later two more bison appeared on the boardwalk by Belgian Pool. These two moved a bit faster, with one going behind Grand and the big rock, while the other passed in front of Percolator and crossed the runoff channel. Once again, they ignored activity from Turban.

It wasn't until the sixth Turban after the Delay that we finally got our Grand eruption. The sun had long set, but it was still bright out, and not too cold. The Turban start of the eruption was explosive, with Vent starting to overflow almost immediately. Grand booped several times before it also began to erupt. It was dead calm, so the highest jets had to clear the growing steam cloud, which then turned into a nice rolling base surge.

Eight minutes into the eruption Grand had a false pause. But it did manage to finally stop at just under 9-1/2 minutes. It was difficult to see, but it appeared there was water in Grand's vent. It was a long pause, and the second burst was just long enough to qualify for the Long designation.
