Observations for 2022 July 12


Woke up about 6-1/2 hours after the previous Grand eruption to see a report that Turban had erupted about a half hour earlier. Made the assumption that this meant that Turban was in the middle of a Delay interval. Had earlier decided that it made sense to skip a short interval. But with the delay , it mean that we had plenty of time to get out to Grand and see the eruption.

Turned out that could've slept in another hour or more, because it took nine Turban eruption intervals before Grand finally erupted. Another One Burst Grand that lasted just under ten minutes.

Did get a bonus, as Castle started while untying the bikes. The first few minutes of the eruption were filled with pauses, then around the six minute mark the play became continuous, and we got a nice major eruption.

The next Grand interval did not have a Turban delay that anyone observed. But it still took almost two hours of Turban eruptions that never looked promising. Then we got an early fill and a One Burst Grand eruption that lasted 8m16s. After the burst, the pool held water for maybe ten or fifteen seconds, then drained. At least Vent & Turban made no attempt to slow down and stop.

Next it was over to Geyser Hill to see what Beehive might do. Waited about 45 minutes, and there were a few nice splashes from Beehive, but nothing much to get excited about. Then there was a large surge, maybe 5 meters high, followed immediately by another surge that lifted into a full eruption. The water column for the first 20 seconds or so appeared to be shorter than most starts I've seen, then it climbed up to full height.

The Indicator joined in briefly during the middle of the eruption, and the duration was longer than normal, perhaps because of the less powerful start.

During the wait, Lion had made several weak surges. It was about time for another series to start, so headed in that direction. Got to Lion just as the initial eruption of the series started, and had to make sure to not be downwind.

During the eruption, I saw something which may or may not be normal. In Big Cub, I caught on video a blip of water, maybe a few cm high. It was not any higher than the back rim of the vent. A review of the video shows that I wasn't imagining things, but it lasted only a few frames.

Saw the next One Burst Grand as I was passing the Inn on my bike. Watched the rest of the One Burst eruption from Castle.
