Observations for 2025 June 07


Grand is starting to get stuck in a mode where it erupts almost exactly three times a day, eight hours apart. Once again went out for the first eruption of the day just before sunrise. At least today there wasn't any ice on the boardwalks.

Castle was still putting out some noise at the end of a steamphase. Despite it being well over seven hours, Grand still hadn't erupted, thanks to the Rift eruption last night.

Only waited two quick Turban eruption intervals before the One Burst Grand eruption started. It lasted only 9-1/2 minutes and should've had another burst. What little breeze there was pushed the misty rain over the boardwalk from West Triplet on north.

Afterwards, I noticed that Uncertain was splashing and gurgling heavily. A short wait gave me a short Sawmill eruption where the starting water level was out of sight. As soon as it ended, Uncertain started to overflow and burst up. It took a while for those burst to build in height to a full, normal eruption.

For the wait for the mid-day Grand eruption the Turban eruption intervals varied greatly, from over 22 minutes to barely over 16. Then West Triplet started to erupt and Grand followed before West Triplet ended. The first burst only had about ten seconds of Big Sawmill before Grand paused. The second burst lasted nearly a minute, and an eruption lasting just over ten minutes had Vent & Turban quitting.

Before sunset Grand had the possibility of erupting before sunset, but it didn't happen. Instead we got a series of non-descript Turban eruptions, then a long West Triplet eruption. Grand did manage to have the One Burst Eruption right after the end of West Triplet. There was still a fair amount of light, and the moon, so it wasn't necessary to illuminate the eruption. It was still fairly warm, and the wind from earlier in the day had disappeared. The only drawback was that during the wait, we were subjected to an obnoxious family that only left two minutes before the Grand eruption.

We also got to see another 3-1/2 minute Castle minor during the wait.
