Summary:

Pg. 3, 27. Cave Creek gypsums or Cave Creek formation [in Cimarron group]. Gypsum-bearing formation, 50 feet thick, consisting usually of either a single stratum of massive gypsum or two such strata separated by red clay shale. Includes (descending): Shimer gypsum, about 8 feet thick; Jenkins clay, 7 to 10 feet thick interval of red clay; and Medicine Lodge gypsum, 25 to 30 feet thick. Overlies Flowerpot [Flower-pot] shales and underlies Dog Creek shales. Is top formation of Salt Fork division. Age is Permian. [In 1897 (Amer. Geologist, v. 19, p. 351-363) Cragin made Dog Creek shales top formation of his Salt Fork division.]
Named from exposures on Cave Creek, Comanche Co., KS.

Summary:

Pg. 236 (Obsolete Oklahoma names). Cave Creek gypsum of Cragin (1896). In Oklahoma, a third gypsum member, the Ferguson, occurs, and the 3 gypsums (Shimer, Medicine Lodge, and Ferguson) with associated dolomites and clays are now known as the Blaine.

Summary:

Pg. 1751, 1793. Cragin's "Cave Creek formation" is identical with Blaine formation of Oklahoma. It is here divided into (ascending) Medicine Lodge, Nescatunga, Shimer, and Haskew gypsums. Cave Creek has priority, but the Blaine has wider accepted usage.
