Pedestals and Petrified Wood

Last week I was asked by an associate if I could send some geology pictures to a student. A rather broad request given the thousands of geology pictures I have in my picture files. What came to mind was perhaps a bit random, but deviated from my Washington State geology and geology hazards pictures.

During my time at Petrified Forest National Park I was fascinated by erosional pedestals formed by hard blocks of rock (in some cases the rocks were petrified wood) protecting much weaker underlying rock or sediment.
