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.

Nathan view of the same eruption. [Bigger]

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]
