Observations for 2023 August 24


Out to Grand on a foggy, damp morning. Only waited one Turban eruption interval, which turned into a Turban Delay eruption interval of 33-1/2 minutes. Because of the fog, it was hard to tell what the pool was doing after Turban started erupting. But a minute in, Turban was still powerful and vigorous, and the steam over Grand's pool seemed to have increased. So I wasn't surprised when after 1-1/2 minutes of Turban erupting, Grand started also. This was another long One Burst Grand eruption lasting almost 11-1/2 minutes.

With Little Squirt active yesterday, and nothing much else going on, decided to spend time on Geyser Hill over by Aurum. The vents were splashing around, but I don't know enough about it to know if we were close to an eruption. In any case, about a half hour later we got the call for Beehive's Indicator. I arrived at the benches just in time for Beehive to have a huge surge and being erupting. After the Beehive eruption, Lion had the second eruption of its series.

The midday Grand eruption was similar to this mornings, where once again Grand erupted after over 31 minutes of a Turban Delay interval. This time Grand started the eruption with an explosive burst as high as the trees, as seen from the benches. And once again, it was a long One Burst Eruption.

Went out early for the next Grand, because it was the first nice sunset, with no wind or clouds, in quite a while. Ended up seeing another Turban Delay interval, this time at the 5-1/2 hour mark. But the One Burst Grand occurred only three Turban eruption intervals later, so the Grand interval was just over 6-1/2 hours. By then it was dark. Only four geyser gazers were there for the start, but the quarter moon gave plenty of light so no flashlights were used.

The last several minutes of the eruption were Big Sawmill mode, and just as Grand ended, Castle started. The minor eruption was over by the time I was packed up and walked over there. Not unexpected, as there have been several major Castle eruptions in a row.
