Observations for 19 June


The morning hot periods were a bit disappointing. I was expeciting a bit of a wait, and the first one occurred within minutes of my getting settled in. Doing the math, I realized there was no reason to go back in, as Grand would be due in a few hours more, and besides, the next hot period might be the real one.

As it turned out, I went to Grand, and caught a Penta eruption, too. The geyser fog was as good or even better than I remembered it. I really enjoy it when it's so thick and patchy that you get situtations like you can't see Sawmill group from Grand, but Beauty and Chromatic to the north are easily visible by their immense steam columns.

Back at Giant, things got progressively weaker, so that as noon approached, it appeared as if the platform was in a post-marathon phase. Both Scott Bryan and I noticed and commented on this at about the same time, how it reminded us of what things looked like last week. But this time, just as everyone was about to abandon the Bijou Cage, water rose in Mastiff and we got a fairly good (but not great) hot period.

So the rest of the day was a series of disappointments, at it just seemed that Giant did not want to erupt, and was using the hot periods to make that clear. Then we got a Grotto start which turned into yet another marathon, about the fourth for this interval. Ultimately, a less than satisfying day.

At sunset, we did get the first bug-hatching of the season. The Firehole River by the Castle-Sawmill bridge was thick with all sorts of insects, and the trout seemed to be actively feeding too. Over at Grand, the mosquitoes were not quite thick enough to be annoying, but it is definitely time to find that bug juice.
