JSON
WOODWARD- Red-brown and greenish-gray shale and siltstone with some orange-brown fine-grained sandstone and siltstone. At base are two or more thin, pink to maroon to greenish-gray dolomite beds and (or) gypsum beds ("Moccasin Creek Bed") eroding into a mappable escarpment. About 25 feet above the base is a white to light-gray dolomite ("Day Creek Bed") not mapped. Thickness ranges up to 160 feet, with top eroded in many places. CLINTON- Reddish-brown to orange-brown shale, interbedded with siltstone and sandstone in the middle part and some dolomite and much gypsum in lower part; thickness about 400 feet, thinning northward to about 175 feet. The "Moccasin Creek Gypsum Member" is at the base. LAWTON- Represented in this area by the "Moccasin Creek Gypsum Member," which is about 30 feet (9 m) thick.

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.
