Hole in the Ground

Hole in the Ground is a physical feature found near Fort Rock. It is located about 6-8  miles directly behind the rock as it is viewed from the museum.  Although  some would like to believe that Hole In The Ground was caused by a  meteoroid, it is a maar, a volcanic crater formed by steam explosions.  The crater is approximately 300 feet deep and a mile wide.
