Observations for 2025 August 26


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.
