|Cretaceous sedimentary rocks|
Age: Late Cretaceous (86.3 - 100.5 Ma)
Stratigraphic Name: Dakota Formation; Mancos Formation; Pinkard Formation
Description: Tan sandstone (Dakota Sandstone) overlain by gray shale (Mancos Shale); deposited in beach, river delta, and shallow sea settings. The Mancos Shale is overlain by the Mesaverde Group (map unit Kmv). This unit includes related sandstone and shale exposed near Show Low, Morenci (Pinkard Formation), and around Deer Creek south of Globe. (about 88-97 Ma)
