Observations for 2021 August 10


With Fan & Mortar erupting before midnight, this was another good day to be elsewhere. But did manage to see a couple of Grand eruptions, neither with much of a wait.

The first was at dawn, with ice starting to form on the boardwalk. Got there early in a Turban Delay interval that lasted almost 30 minutes. In the middle of that, Castle started, and actually had a major eruption. The One Burst Grand eruption started out wetter than I would have liked, but was mostly visible from the north end.

The second Grand eruption was early evening, with the sun low, but behind clouds. Only waited one full Turban interval, and towards the end, the clouds cleared so that we got a nice sunlit eruption with rainbows. The first burst was only 8-3/4 minutes, and when the pool continued to slosh around, it became apparent that we were getting a second. A tall, wide second burst that developed into a a second burst that lasted well over two minutes.
