Observations for 2025 August 23


Another morning for a pre-dawn Beehive eruption.

With nothing much going on, went down basin to do some watching. Went to the Bijou Cage where everything seemed dull and normal. Shortly after I arrived, I noticed that one of the vents on the platform was now filled with water and pulsating. It's been so long that I thought I was seeing Feather, and reported it as such. As the time went by, this vent would alternate every ten to twelve minutes between full and with no water visible. Upon further thought, I decided I was probably wrong in my identification, and a check on the map when I got back to the cabin confirmed that all I was seeing was Emerald. I know it's been full of water in years past, but I wasn't aware that it fluctuated like that. In any case, time to take the map out on the iPad for my next wait so I can get things right.

After that, went out to Grand for a mid-day eruption. The past few days the afternoons have been warm with very little to no air movement, making it almost uncomfortable waiting out there. A couple of Turban eruption intervals after arrival, West Triplet started to erupt. Since Rift had been observed during the night, it wasn't the start of a major delay, and I hoped that it might indicate Grand would erupt soon.

Turned out that instead it took a couple of Turban eruption intervals after West Triplet ended before we got the eruption. Two burst, and the pause between the two burst features the pool sloshing about for most of that time. It looked like it should have the second, but experience said that it could drop any time. As it was, the first burst was during a calm period, and quite high, while the second burst was cut off and shorter due to a burst of wind.

Beehive had a short eruption interval preceded by a long Indicator duration. This morning the indicator lasted about twelve minutes, just long enough for me to get to Anemone for the start. This time the duration was well over 25 minutes, approaching thirty.

After that it was time for another sit at Giant. On the way past Economic, I noticed that it was overflowing strongly, with runoff under the walkway and about ten meters beyond. When I returned about an hour later, Economic was well below overflow, with the water in the inner rim, and all the evidence of the runoff under the walkway was no longer visible.

It was at that point that we thought we were seeing Turban start, but instead it was Grand, with a 7h12m interval. Was almost disappointed, as had expected and planned on the eruption taking place in the dark. But instead there were a few high sunset rainbows. The first burst was long enough to be the only one, but instead, like earlier today, the pool filled quickly and then sloshed around for close to a minute before finally erupting again. This time it was nice and tall.

 19:48:42	West Triplet

West Triplet started during the first burst. Waited around for the expected eruption of Rift, which occurred about 37 minutes after West Triplet started. Also while waiting Uncertain erupted. West Triplet was still erupting as we left the area after seeing Rift's runoff reach the boardwalk.
