Observations for 2026 August 24


Based on the recent short intervals, headed back out to Grand before the seven hour mark, while it was still dark. Ended up waiting six Turban eruption intervals. For most of the wait the breeze was non-existent, but during the eruption the benches on the north end got soaked, and I'm sure there's not much to see on the video

Afterwards, decided another wait in the Bijou Monkey Cage was in order. One bit of Guru Geyser Gazing I've noticed is that the events of the last few days have come on six hour (or multiple of six hour) intervals. The meant that we had a chance for something to happen around noon.

After a two hour wait with only small Mastiff far vent surges every 10 or 20 minutes or so, we got a large surge. Bijou was already completely off at that point. Shortly after, water was visible rising in Mastiff. At first there were a few spits from the Southwest Vents, and some splashes from Catfish. A minute later the Southwest Vents were putting out a couple of streams of runoff. We also noticed that water appeared to be pooling in Feather, but it was hard to be certain.

Bijou came back on after a pause of at least 4m17s. Catfish also had some tall surges, and the "C-B Vent" erupted briefly to about 20cm.

Before the event started, there were a group of four men talking at the other end of the platform, and it sounded like they had some knowledge of geysers and the Giant area. Just before the event started, it looked like they had started an on camera interview. So in the background of their video they have Suzanne and I suddenly climbing the bench and staring at the platform, with Suzanne making announcements over the radio for the duration.

They may have been doing a video for the YVO or some such. In any case, I'd definitely be interested in hearing if anyone sees such a video.

During that wait, I also heard a woman in a family group ask, "Which one's Giant?"

Got back to the cabin (after a forced NPS bison babysitting detour) and shortly after got the Beehive radio call. During the eruption I noticed a small vent squirting water out to the north from a hole about 15cm above the platform to a distance of about 1/4 meter. It quit with Beehive's Indicator. It was windy, so the eruption of Beehive got the usual stretch of boardwalk wet.

West Triplet started erupting just as I tied my bike down at Castle. With no following eruption of Rift, I expected a wait of a few hours until the next West Triplet eruption window. Two and a half hours later, Grand filled nicely, followed by almost 15 seconds of boops before the One Burst Eruption started. Midway through that, West Triplet started erupting.

Since it was nearly six hours since we saw the Mastiff bathtub hot period, we went down to the Bijou Cage to wait and see if the six hour intervals would hold. Ten minutes after arriving, we got a huge surge from Mastiff, which lead off a shorter and weaker bathtub. While the water level in Mastiff seemed the same, there wasn't any Southwest Vents activity other than a few spits, and the Bijou pause was shorter. The next two opportunities are going to be in the dark, and we won't be attending.
