Observations for 2025 September 02


In the predawn hour, just outside my cabin, I encountered a deer as I was headed toward the indoor plumbing. It was still there, but took off, as I returned.

Went out to check on Grand next, and found that it had erupted as I was getting prepared to go out. I did see a steamy runoff channel from Rift, indicating that it had quit during or just after the Grand eruption.

Back to the cabin, where it was time to make a quick sandwich for breakfast. Just as I put the jelly on the bread, get a radio call for Beehive's Indicator in eruption. The sun was low and it was calm, with a nice rainbow at the top of the water column and in the rainfall.

It was during Beehive's eruption that another radio call came through. This time it Fan & Mortar were finally having an observed event cycle, with Main Vent splashing and Bottom Vent erupting. So after returning to the cabin, got on the bike and headed on down. Nothing much came of it, but it's nice to see something happening there.

The afternoon eruption was really a wait for West Triplet to erupt. The Turban eruption intervals were fairly short, and it wasn't until West Triplet erupted that Grand showed that it might erupt, by having the Turban intervals get shorter. The One Burst Grand eruption took place on the Turban eruption immediately after the end of the West Triplet eruption. The start was nearly simultaneous, with Grand having a boop, then Turban, then the Grand start, all within a couple of seconds. The eruption itself was long, almost 12-1/2 minutes long.

Back out to Grand in the dark, but with a nice moon until well after midnight. An hour after arrival West Triplet started, triggering Rift to start just before midnight. Waited a few more Turban eruption intervals, then as the moon was setting, decided to give up and head in.

Had just approached the bike rack at Castle when we heard the radio call for Beehive's Indicator. So bicycled back to the cabin and headed for Geyser Hill. The moon had set, so the bright lights were on. I was at Anemone when it started. Was quite impressive.

Returning from Geyser Hill we saw a large steamcloud to the north. Grand was erupting.

Back at the cabin, headed to the indoor plumbing and in the light from the streelight I saw a head poking up from behind the rocks along the drive. Was being watched by a deer just downslope from the road. Leaving the restrooms I was surprised by a second deer running out from the cabin area, across the road and running down the hillside. The first deer on the slope was still there, watching me. Then it moved away and I lost sight of it.
