The Capitol Reef region which includes the recently established Capitol Reef National Monument exhibits in general the stratigraphic, structural, and physiographic features of the Colorado Plateau Province. In the canyons of Fremont River all the Triassic and Jurassic formations elsewhere exposed in southern Utah, likewise the displacements caused by the Water Pocket Fold and the Thousand Lake fault, are well displayed. Special local features are the thinness of the Chinle and Shinarump, the presence of much sandstone and limestone in lower Triassic beds heretofore classed as Carboniferous, the unusual composition of the San Rafael group, and the extensive surfaces of erosion about 300 feet above present drainage channels.
