Observations for 2021 August 24


No reason to go down basin, so off to Grand instead. The walkways were just starting to ice up, and it was hazy from the smoke. The One Burst Grand was somewhere in the large steamcloud we saw. During the eruption Castle started, but we weren't sure when. By the time got over there, it was in steam.

Midday was time for another Grand eruption. This one had two nice bursts. The first burst tried to pause at the eight minute mark, then continued for another 20 seconds. Afterwards I waited a bit at Sawmill, as it was as full as I've seen it this year, but after about 15 minutes, nothing had changed. It still wasn't in eruption as I left from Castle.

From there it was off to Geyser Hill for Beehive. By then it had gotten windy, so the Beehive eruption was sending a curtain of spray all the way to Infant Geyser. Also, the Base Vent bubbler was active for a brief time as the Indicator quit.

Arrived at the sunset Grand as West Triplet was ending an eruption. Sawmill was also in eruption. The group seemed to be fairly full, at least for this year. Slurp was actually quiet, despite the lack of water coming in from a low Crystal.

Bison at Oval Spring

At some point while waiting for Grand, a bison moved into the Sawmill Group. It bedded down for a while right next to both the boardwalk and Oval Spring. It was so close to the walkway that for once, no one tried to walk past it.

As the bison appeared, Grand had a Turban Delay Interval. Fortunately, it delayed the Grand eruption by only two Turban eruption intervals, so there was still plenty of light to see the eruption. Again, we had a short first burst and a nice second burst.

The bison had moved over into the trees as we left.
