The forces of erosion are sculpting more than just arches in the Entrada Sandstone. At Balanced Rock, the caprock of the hard Slick Rock Member is perched upon a base of the Dewey Bridge Member, a mudstone. This softer pedestal weathers more quickly than the resistant Slick Rock above. Eventually, the faster-eroding Dewey Bridge will cause the collapse of Balanced Rock.
