Glacial Striations in Devil's Postpile (Updated over a year ago)

You can view this bundle in the Earth - A Work in Progress collection area.

Photo of the octagonal rock formations at Devil's Postpile. The stone shows signs of glacial striation, which are parallel lines or grooves in a bedrock surface. They are formed by the deposition of loose rock material that was once embedded in a glacier that has passed over the rock surface.
