Hole in The Ground

Today we explored some interesting geological phenomena in the open high desert SouthEast of Bend.

First off was 'Hole in the Ground', which is a huge crater-like depression in the middle of fairly flat terrain. It was created from an old volcano that spewed tons of ash out which landed in a circular pattern around the center and built up over the years.

Jackrabbit carcass. Lots of questions about this :)

Next was 'Fort Rock', a massive rock monolith rising out of the desert. I forget the creation story, but something to do with harder igneous rock that wasn't worn down like the surrounding terrain.
