| This view of Fallen Rock illustrates the geologic processes that are shaping the landscape at Colorado National Monument. Fallen Rock is a great 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. The ongoing pull of gravity along with weathering and more erosion will eventually break down the great block into sediments to be carried away in the storm-induced flash floods and high stream levels following heavy snow melt in the high country. |
