Observations for 2026 August 31


In the morning, did not head out until it was time for Grand. Glad I didn't try for the nighttime eruption, as the interval was about nine hours.

Walked up to the Grand Group with West Triplet full of water and starting to drain. Shortly after was a Turban eruption that was much shorter than typical.

Grand tried to have a Delay on the next Turban eruption interval, and failed. Instead we got 75 seconds of boops, including one that may have been five meters high.

After that, the One Burst Grand was pretty normal, although there was a short false pause at about the time a real pause would have been nice.

Sawmill was erupting, but Uncertain was pooling on occasion, so stuck around for that. Also got a Castle major eruption while waiting for Uncertain, which seemed to have a shorter duration than previous occasions.

Went on down to the Bijou Cage to see what was happening. Bijou was on strong, but not as high or powerful as it was before the eruption. Catfish was having occasional splashes also. Mastiff was having small surges from the back vent, while there was no depth charging from the front. The Southwest Vents were steaming gently.

A half hour at Fan & Mortar was a place to kill time before going over to see an eruption of Daisy.

West Triplet was erupting as the time of the evening Grand eruption approached. Forty-five minutes later, West Triplet ended just as Rift started to erupt. Except this Rift eruption was weak, and lasted less than 20 minutes. I watched the last minute, and the eruption activity by then consisted of a single vent sputtering to about 25cm, with no overflow.

A half hour later we got the One Burst Grand eruption. The sun had disappeared behind a layer of clouds, and there was only a hint of rainbow in the spray from Vent.

Also, why is it necessary to add the redundant comment "saw it" to a geyser eruption entry?
