Observations for 2026 September 07


Once again it was out to the Bijou Cage at dawn to see what had transpired overnight. It wasn't possible to tell, as it had rained a few hours earlier.

The day started out cold and overcast and blustery, and by mid-morning was cold and sunny and blustery. Probably the most unpleasant day so far this visit.

In the Cage, there was a Standard Bathtub shortly after I arrived, and there was another about an hour later. All through the day the occurred one to two hours apart.

At Grand, there was a nearly ten hour interval, this time without a Turban Delay Interval. The whole time West Triplet was quiet, but West Triplet began erupting during the Grand eruption, which like yesterday's long interval eruption, had two bursts.

Later sessions in the Bijou Cage yielded some Standard Bathtubs and an event where Mastiff showed water but Bijou never shut off. It's looking like things at Giant may have stabilized, which means either no eruption for a while, or an eruption getting ready.

Decided it was a good night to not go out to Grand until later in the window. So I was at Crested Pool when the 7-1/2 hour interval One Burst Eruption started. West Triplet was also in eruption by the end of Grand's eruption.

On the way back last night, in the dark I noticed large puddles of water near my cabin. Steaming puddles. It seems a new hot spring broke out next to Cabin #230 across from us, and was flooding the area. Because of this, the cabin area had no hot water until the repairs were done today.
