Something in the nature of the spectacular is often afforded visitors to the Lake, when enjoying the boat trips. The cliff above being almost perpendicular, a small rock becoming dislodged may create a considerable rock-slide. The roar of this descending material can frequently be heard for a great distance. The huge boulders dashing into the water, and the clouds of dust which trace their path offer a sight worth seeing.

A nature party on the rim was recently observing the antics of two chipmunks which were skirmishing around among the rocks and along the slope of loose gravel and sand above the topmost layer of lava. One of these chipmunks presently dislodged a small pebble, and in rolling this loosened others; soon a very respectable slide was cascading over the lava cliff onto the slope below, gathering more material there and continuing on downward toward the lake.

The slide was hardly of proportions to attract attention, but had it been observed, any guesses as to origin would hardly have included a chipmunk among the possibilities.

The first family of camp-robbers are reported by Ranger Robert Beck, from the West Entrance. They are already sociable and make the checking station their headquarters.
