Most of the cliffs in the Canyon of Lodore are sandstones of the Precambrian Uinta Mountain Group. However, sedimentary rocks of Cambrian and Mississippian age crop out along the upper part of Dunn's Cliff (the light-colored upper portion of this view). The Lodgepole Limestone (Mississippian) forms the top of the cliff. Juniper and pinyon-pine forests grow on the the slopes and crevasses throughout the mountainsides.
