Observations for 28 May
Went up to Daisy and Splendid again on Sunday afternoon, early enough that I could watch the activity prior to Daisy's eruption. I was there for half an hour, and during that time, saw exactly one boil from Splendid's main vent, about a half meter high and lasting only a few seconds. Disappointing.
Later Sunday evening, Grand finally made up for all the nice short intervals it's had by tossing in a long interval, which these days is a measly 8h13m. (Ahh, for the good ol' days when a "long" was over 16 hours, and a short just 10.) I never really had a delay overflow, just alternated good looking overflows with ones that were obviously not going to result in an eruption. At the same time, the weather deterorated. It got cloudy and gray, and eventually we started getting sprinkles. FInally, at 20:03, it had what was a "Classic Two Turban Delay" — heavy overflow with waves, a drop as Turban starts and a short eruption of Turban (2m59s). That was followed by a short Turban interval (17m08s)and finally on the second Turban, the eruption. The eruption itself presented a nice contrast between the white watercolumn from Grand with the gray clouds as a backdrop.
This Monay morning was mixed. The weather was clear and could have been warm if the wind wasn't gusting up to about 40mph, or so it seemed. Grotto's marathon ended somewhere around 03:00-04:00 (best guess), and Grand went at 03:10, according to the monitor. So instead of spreading things about, Grand decided that it was time to experience a Rift delay. This resulted in everything interesting happening in a little over a half-hour span. First, this time someone saw the Indicator in eruption, which resulted in a stampede to the south. They returned in time for Grand to finally erupt. While it was a two burst eruption, it took Grand a full minute after the start of Turban to begin, and the total duration was only 9m29s, yet Vent and Turban quit afterwards
Within ten minutes of the end of Grand's eruption, Giant had its post-marathon hot period. The hot period was fairly strong, with Mastiff boiling mostly to one or two feet, with a max around four,but for almost the entire duration.It lasted 9m52s, then was followed by about 3m30s of a Feather restart but with weak Giant surging.
Other Geyser Times
28 May- Rift 10:09, d≈50m
And nothing to do with geysers
On my way to Grand last night, I saw a duck floating on the Firehole River, then shooting the rapids below the Sawmill bridge and drifting off downstream.
