Observations for 2024 May 31


Just after midnight we heard the radio call for water in Beehive's Indicator. Had plenty of time to get out there for a nicely illuminated eruption that started with a huge surge of water, maybe 10meters high. With no wind, the water column went straight up and then straight down.

Later went out for a half-hour of undistinguished Turban eruption intervals, followed by a nice two burst Grand eruption. The first burst lasted 8m21s, which has been known to be the duration of a One Burst Grand eruption, but not this time. Instead we got a second, 2-1/2 minute long second burst. Both bursts didn't seem to be very tall.

It was after Grand when the trail closures were lifted. Since I hadn't really had a chance to go down basin, finally got to do so early in the afternoon.

Got to Daisy in what was the latest part of the published window, only to find it completely dead. Having nothing better to do, decided to stick around see the build up to the next eruption. Turns out there was a double interval of about 1h45m for each. The duration was still 3m22s, but it does seem that the intervals over the years are getting a little shorter.

(When I arrived, there was a raven working on the remaining bits of a small animal located just behind the bench.)

During the Daisy eruption the call came over the radio for water in Beehive's Indicator. So once Daisy had finished, I rode down to the overlook, after dodging a bison grazing where the trees and the warm ground meet. Beehive started as I passed through the little grove of trees.

The wait for the evening Grand eruption was also uneventful. The lighting was nice, and the wind had finally died down. The first burst lasted just under nine minutes, but the pool looked full once the steam cleared. This time the burst heights seemed taller than earlier. In both cases, Vent and Turban restarted within ten minutes.

Afterwards there was a long Bulger eruption, but not even steam from Bulger's Hole. Spasmodic had been overflowing earlier, but was dropping. This is the first time in years, since Sawmill reactivated, that I have seen that. Would like to see Sawmill overflow before erupting, because I think that would indicate a Penta major eruption could finally happen.
