| Kungurian - Moscovian 272.95 - 315.2 Ma ID: 2993666 | Permian to Pennsylvanian sedimentary rocks Age: Paleozoic (272.95 - 315.2 Ma) Stratigraphic Name: Hermit Formation; Supai Group; Schnebly Hill Formation; Naco Group Description: Interbedded sandstone, shale, and limestone usually characterized by ledgy outcrops. Orange to reddish sandstone forms cliffs near Sedona. This unit includes Supai Group and Hermit Shale in northern Arizona and Naco Group in southern Arizona. It was deposited in coastal-plain to shallow-marine settings during time of variable and changing sea level. Rocks of this map unit in southern Arizona may be in part equivalent to Permian rocks of map unit P in central and northern Arizona.
