Twilight Over Mt. Garfield
Book Cliffs
Mt. Garfield, a prominent feature of the Book Cliffs Range that stretches from Western Colorado deep into Utah to the west, stands approximately 1,500 feet above the Gand Valley. Composed mostly of Mancos Shale badlands along its flanks, the Book Cliffs that run along the northern edge of the Grand Valley is capped by Mesa Verde Sandstone. This top layer of sandstone protects the softer shale below from quickly eroding away. Photo © copyright by Chris Eaton.
