Little Crater Lake

The texture of the walls were interesting and the water so clear that you wouldn't know you were underwater if there wasn't particulate floating on the surface.

Tree underwater

It's interesting to me that so many trees are felled here. I would like to return just to see what becomes of them.

Ascending

The water is so clear, that it is easy to wander.

On the brink

Nearly at the surface, seeing my buddy rise to the ceiling of this lake reminded me that we indeed were still underwater.
