Month: June 2025

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.
