Colorado National Monument - Fallen Rock

Detailed Description
This view of Fallen Rock illustrates the geologic processes that are shaping the landscape at Colorado National Monument. Fallen Rock is a block of Wingate Sandstone that split away from the cliff where Ute Creek had undercut the softer shaly sediments of the Chinle Formation along the creek bed. More erosion will eventually break down the great block into sediments to be carried away by water.
