Observations for 2024 September 03


For the morning Grand, once again had a short wait for the One Burst Grand eruption. West Triplet did overflow for a while after the eruption, but this time there wasn't any convection or thumping.

Going out for the next Grand eruption, as I passed Crested Pool I noticed that it seemed the ospreys were making a bit of noise. Then I saw the reason-- there was an eagle flying low headed upstream.

The wait at Grand was a long one. As we approached the eight hour mark, Grand finally looked like it might erupt, only to suddenly drop and then sit for long enough for it to be a Turban Delay interval. As expected, Grand finally had it's One Burst Eruption four Turban eruption intervals later. After the eruption, I noticed that the runoff from West Triplet was wet, indicating that West Triplet probably had a decent overflow during the Grand eruption.

Before the Turban Delay, Beehive's Indicator was called over the radio. Not only did this cause a mass evacuation of most of the gazers who had been waiting, but it appeared that many of the visitors followed them, as the benches seemed empty.

After Grand erupted the Sawmill Group was in the proper state for an Uncertain eruption. Uncertain was noisy, but there wasn't much splashing. After waiting about half an hour, suddenly Uncertain's vent filled with water, and with 15 or so seconds, the eruption started. As the Uncertain eruption was ending, Sawmill started to erupt. That eruption lasted for about 50 seconds, and then all was quiet.
