Arches National Park: Balanced Rock
From a distance we can spot it. There, second from the left, is Balanced Rock, a 55-foot boulder perched atop a slim column. 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.
