Observations for 2021 May 27


In the middle of the night got a notification of Beehive's Indicator erupting. Got out too late to see it, but did confirm that the bubblers near Little Squirt were quiet (but the boardwalk was frost free) and did see Old Faithful on the way back.

Not much reason to go to Norris, so decided to skip the day and see geysers. The morning's One Burst Grand was nicely back lit, very steamy but the wind was from the north. Afterwards, went down to see Fan & Mortar in Angle/Garbage mode.

I thought I'd seen Daisy heading out to Grand, but was mistaken as I arrived at what I thought was well before the two hour mark, and Daisy was nowhere near ready. The eruption itself lasted on 3m09s, which seems to not be unusual this year.

The crowd at the early afternoon Grand looked like one that is waiting for an eruption in July. As it was, they got to see a three Turban Interval Delay. The Delay interval was short, only 25-1/2 minutes, but sufficient. The next two Turban intervals were short and had little to no overflow.

West Triplet continues to overflow fairly steadily, with no signs of erupting. It has also taken on a brownish color. The flow picks up during and after Grand, and can be little more than a trickle otherwise.

Afterwards, came across Crystal Spring having one of its major slopping episodes, where water floods out over the rim in all directions. Waited about 20 minutes for a repeat, but all I got were some brief slaps against the shelf every three minutes or so.

Went out early for the late evening Grand. Saw Turban erupting as I tied up my bike. The next Turban eruption was 35 minutes later. Since it was less than 5-1/2 hours since the earlier Grand eruption, I wasn't surprised there wasn't an eruption. Fortunately, the Delay was only for two Turban intervals, and it was still pretty light when Grand started. The first burst lasted under eight minutes, so we expected and were rewarded with a second burst that lasted just over a minute. Long enough that we didn't get the third burst, and Vent & Turban didn't quit.

After leaving Grand, noticed that Sawmill was higher than I've seen it in years. And it was still rising. It was getting dark, but the reflection of the sky in the pool seen from over by Tardy showed the level pretty clearly. It appears that it got to the point where overflow was starting, and then the pool dropped. There might have been some water flowing under the gravel in the runoff, as there were several areas that looked wet when we left.

As we left, I also noticed that Churn was down slightly, stopping most of its overflow. The level was similar to that following an eruption of Churn.
