Observations for 03 July
If I hadn't known that it had erupted the day before (at 14:33 on 02 July), I could have been fooled by Fan & Mortar's behavior this morning. Around 06:00, only about 16 hours after the eruption, I got to see a perfect example of post-eruption type activity. The water levels are low, which seems to make the normal splashing and surging that F&M are always doing even more vigorous. During the fifteen minutes I was there, Mortar's Bottom Vent was erupting most of the time, with some bursts to two meters. This produced overflow down the various catchbasins and into the river. On the Fan side, the Main Vent as the star. As it always does, the surging in the two geysers dies down only to be followed by a quick restart. A number of these restarts were accompanied by Main Vent splashing well above its rim accompanied by explosive sounds. But none of the other signs of high water were there, so time to move on.
Grand appears to have had two long intervals in a row. The second, daytime one was accompanied by Rift. The Turban intervals leading up to the eruption started long but after a couple got progressively shorter until dropping just under 17 minutes. Some of the sputs between Rift and Grand have reactivated, but have only been seen for a few minutes, unlike past years when they could be active most any time.
Giant is dead for now. The platform was mostly dry. I was told that the puddles that I did see were probably due to huge cone-filling surges out the front that look impressive, but mean little. Mastiff is having the same sort of activity, but there are no real hot periods any more. Some day this summer, it's just going to erupt without warning, just like it's done in past slowdown years.
For a short trip, it doesn't make sense to not take advantage of a geyser I wouldn't put in the same effort if I were here for weeks or months. Since it was obvious that Grand wasn't going to be anytime soon, I went to Geyser Hill and waited for Beehive. Perfect conditions, dead calm but warm enough that the steam wasn't obscuring. I was able to stand on the boardwalk closest to the cone and see a double 210° rainbow, and only get wet once. (But the umbrella served its purpose there.) I may even have to visit the Lower Basin.
