Observations for 2021 August 17


The day started with a notification of Beehive's Indicator in eruption. I got no farther than the path from the cabins when Beehive started erupting.

The report from Fan & Mortar was no eruption overnight. At that point, it was time for Grand. Saw Turban from the bike rack, which was fortunate, as Grand started 30 minutes later. It was a Turban initiated, and it took Grand about twenty seconds to get going. Just over ten minutes in there was a significant false pause, then Grand continued for well over another minute.

The webcam operators reported a Bulger eruption during the Grand eruption, but I saw no evidence of any activity. The runoff channel was dry both before and after, while Bulger was having it's low boils every so often. They've been reporting a lot of activity from Bulger that I think did not happen.

With Fan & Mortar not doing much, I went over to Daisy to catch what for this year was a long eruption, lasting well over 3-1/2 minutes. Afterwards, the vents on Splendid started quickly, alternating between the Main Vent and the Side Boiler.

The mid-afternoon Grand wait had something special. I had just got there when there was a call of large Upper Mortar splashing. Left Grand and headed toward Castle, just in case. Since there wasn't a follow up, headed back to wait for Grand. Sawmill was erupting all during this time, and the group was well into a deep drain. About a half hour later, got a radio call of Uncertain in eruption. I was able to capture some video over the crowd. This is the third eruption observed of the year, and I've seen all three, the last two while waiting for Grand.

Grand erupted about an hour later, and never had a delay during this time. It was another One Burst Eruption lasting about 11 minutes.

Towards evening, there was a report of Little Squirt in eruption. I went over about an hour later, to check on the frying pans I'd seen active back in May. Little Squirt was still erupting, but the only hint of activity was some slight steaming from one of the frying pan depressions. It might take a while for them to get going at the strength I'd seen before.

Headed out for the nighttime Grand, finding West Triplet, Percolator and Sput D active. Also arrived for a Turban Delay Interval. Shortly after West Triplet quit, I saw my first Bulger major eruption of this trip, thanks in part to some headlights from the Inn parking lot illuminating the area. Got down there just in time to see the eruption end. It was quite obvious that there had been an eruption, with water still flowing down the runoff channel.

Then there was this strange noise that seemed to be coming from the area of the sputs. Finally realized that what we were hearing was Beehive. Maybe the smoky haze was having an effect on the sound.

Two Turban eruption intervals after the Delay eruption, we got another strong Turban eruption that either goes into a Grand eruption, or results in a further delay. Grand didn't erupt. By then, we were seeing flashes of lightning and hearing thunder getting closer. A check of the radar weather maps showed that the odds were we'd get soaked before Grand erupted, so it was time to go. Got back to the cabin just in time for the heavy rain to start.
