Observations for 2024 May 28


Didn't have to wait for a steamy two burst Grand eruption. The first burst lasted 9m15s, which has been known to be long enough for a single burst.

As I was leaving Grand, I saw a rabbit appear from beneath the boardwalk beside Sawmill. It kept ducking under the boardwalk and finally ended up beside Belgian Pool. A minor eruption of Bulger distracted me, and I did not see the rabbit again.

Over at Crested Pool I saw an eruption of Tilt start. I noticed that not only was there no water going into it from Crested, but there was no runoff on that entire west side. It appears that Crested has dropped just enough so that the water only flows out one channel on the east side.

Crested also appeared to be a bit quiet. As the boiling along the west edge picked up, in the low light from sunrise I could see pulses of water pushing into the formation, raising the level just slightly. When the boiling quieted down about a minute later, the pulsations stopped as did the water level. Didn't stay long enough, but a project might be to see if this behavior can be quantified.

Later went out for the mid-day One Burst Grand eruption. Was a dull wait for an interval just under eight hours. The only item of note was that the durations of the Turban eruptions and the intervals between them slowly decreased. The last couple of minutes of the eruption consisted of Big Sawmill mode.

There was only six minutes between the Beehive's Indicator radio call and the eruption, so I saw the start from Sulphide Spring. It was a bit windy, so I got a good view of the curtain of water extending across Geyser Hill.

After, went out to Grand, but over the next hour storms started to develop to the west. With the radar view and the start of raindrops and it getting dark, decided that the odds of anything but a One Burst Grand meant it was time to leave.
