Lakeshore Geyser is under water when the lake level is high, exposed when it is lower.
Here's why the west thumb of the lake looks like a crater. [Bigger]
A nice eruption of a geyser further up the lake shore.

Some fish in the lake near the Fishing Cone. Fishermen used to catch a fish here, and cook it right on the line by putting it over the Fishing Cone. [Bigger]
The Black Pool was black the last times I was here. They say its temperature increased in 1991 and the algae died. It is blue now.
It really does look deep.
A little action in the Twin Geyser area.
More Twin Geyser bubbling. [Bigger]
Not much shade around here. [Bigger]
