Late Paleocene-Early Eocene conglomeratic alluvial fan deposits exposed on the upturned south face of Richards Mountain, on the north edge of the Uinta Mountains. Cliffs typically correspond to boulder conglomerate deposits. The Powell expeditions and subsequent workers discovered that its lowermost deposits contain predominantly Cretaceous clasts, while clasts at the top of the deposit contain Precambrian metasediments of the Uinta Mountain group, in total recording unroofing of the nearby Uinta Uplift.
