The bottom layer is slope-forming Organ Rock Shale, the next stratum is cliff-forming De Chelly Sandstone, and the upper layer is Moenkopi Formation with a Shinarump Conglomerate caprock. The rock ranges in age from Permian at the bottom to Late Triassic at the top. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale ...

The rock ranges in age from Permian at the bottom to Early Triassic at the top. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the ...

Ripple marks in Moenkopi Formation rock. Local climatic conditions were wetter and more tropical in the Early Triassic than they were previously. In the Capitol Reef area the resulting Moenkopi Formation is divided into four members (from oldest to youngest): [6] Black Dragon Member; Sinbad Limestone Member, Torrey Member, and; Moody Canyon Member.
