Summary:

First used for erosion surface across the Church Buttes anticline, Uinta Co, WY in southwestern part of Greater Green River basin. Derivation of name not given. Probably named for Moxa, Lincoln Co, WY. Is defined by a thin sequence of sandstones and conglomerates of Ericson Formation that unconformably overlies the marine Hilliard Shale. Rock Springs Formation is interpreted to have been stripped by erosion from the crest of the anticline prior to deposition of Ericson. Age is Late Cretaceous.
