Observations for 2025 September 03


After last night, not in a great hurry to get out and about. Did end up getting out to Grand Group around the seven hour mark. An hour later it was warmer and drying and we got a nice One Burst Grand. No West Triplet eruption before or after.

In the Sawmill Group Uncertain was splashing and slopping out water, so it wasn't a long wait before we got an eruption there. Did not seem to be as tall as the one I saw yesterday from Grand.

Oblong hadn't been seen this morning, so worth a trip down that way. Economic was in slight overflow, although it is getting oranger. Got to Oblong, and barely had enough time to set up the camera before the eruption began.

About that time came a call that water was splashing in Fan's Main Vent. Got down there and there were still a number of huge splashes seen. Mortar's Bottom vent was also in eruption when Gold and High vent had abrupt starts. High was especially impressive, and if later in the cycle, would have been a really good sign. Instead the activity slowly decreased. But it is encouraging that Fan & Mortar are exhibiting more than short, weak cycles.

From there, it was noted that it had been over a day since an eruption of Artemisia had been seen. A quick side trip showed that East Sentinel was boiling heavily, but there was no sign of any recent eruption. At Artemisia there was first a short wait before an Atomizer minor eruption, then almost immediately Artemisia started. The wind was ideal the entire eruption, with the steam going into the trees and no one having to move to avoid the steam bath.

On the way back, attempted to see a Rocket Major eruption, but instead got Grotto quitting. The dumpster makes for a nice view block for a number of the benches which by then were in the shade.

Just got back to the cabin after having a burger at the Lower Store when suddenly Beehive's Indicator started. So it was back out to Geyser Hill. Little Squirt may have started erupting during Beehive's eruption, because I don't remember seeing it when walking out, and the water was just starting to progress down one runoff channel.

Got out to Grand in time for a Castle minor eruption. Then waited an hour for West Triplet to start. This time Grand had the One Burst Eruption on the next Turban eruption. It was short in height, but long in duration.

Since the wait for Grand was shorter than expected, some of us went down to Oblong to see if we could catch another eruption. Waited until well after sunset, but despite some strong overflows, it did not erupt.
