Observations for 22 May (Morning)


Having been gone a long time, some of the things I'm noticing are probably well known and obvious to those who' ve been here more recently. But I'm still going to comment on them.

Tilt Geyser is completely different. The original Tilt, which had functioned as a noisy steamvent in the 1980s and 1990s, has been completely filled in by algae and debris carried along by Crested's runoff channel. In the several minutes that I stood there, I noticed that the blowout vents were fluctuating between overflow and down about 1.5cm. The changes in level was also accompanied by ripples and palpitations. That, I assume, is the sum total of Tilt's present activity, which I guess would still qualify it as an intermittent spring.

The Sawmill Group appeared almost as I remembered it, with one minor and one major exception. Tardy has developed a new runoff channel which heads northeast and under the boardwalk, which would have been useful when I wanted to put electronic monitors around the group.

The big exception was the new hole (or holes) that have developed beside or even under the bend of the boardwalk at Scalloped Spring. Thanks to the snow showers, it was easy to see the long stretch of warm walkway. The between the walkway and the old collapse feature actually had water sloshing around about a half meter down. I'm surprised the NPS hasn't panicked and closed the trail. If the do, let them wait until July.
