Comments | Named for town of Cloud Chief in eastern Washita Co, OK in Anadarko basin, near which unit is "typically exposed" (Gould, 1924) Consists of ledges of massive gypsums imbedded in red shales. The gypsums vary a lot, both in number and thickness. Maximum development of the gypsums is along axis of Anadarko basin in eastern Washita Co, where 100-ft beds occur. |
