Pg. 65. Cheyenne sandstone. Obliquely laminated, mostly incoherent (rarely hard) sandstone, 20 to 40 feet thick, often gray but in large part gorgeously decorated with crimson, purple, scarlet, orange, yellow, brown, and other colors. Forms bed No. 6 of section at Belvidere, Kansas. Supposed to be referable to Trinity division of Texas and Arkansas. Age is Early Cretaceous.
[Named from Cheyenne Rock, at Belvidere, Kiowa Co., central southern KS.]

In 1895 Cragin divided Cheyenne sandstone into the several "members" mentioned under Elk Creek beds. All of these "member" names were discarded by the USGS in 1921, being applied to local facies of the Cheyenne.
The commonly accepted definition of Cheyenne is that it underlies Kiowa shale and rests unconformably on Permian, the Triassic and Jurassic being absent. Present in central southern Kansas. Age is Early Cretaceous (Comanche).

Cheyenne formation (Cheyenne sandstone). Writer does not consider it possible definitely to recognized any member of Cheyenne formation beyond limits of one locality. Cragin's divisions are considered to have no validity for more than local applications, and as his 3 members were not differentiated in same section it is possible 2 of them may be one. Cheyenne sandstone appears to be confined to eastern part of area of Kiowa shale. Age is Early Cretaceous (Comanche).

Pg. 75-86. Cheyenne sandstone. In Kiowa County, Kansas, Cheyenne sandstone unconformably overlies Permian Whitehorse sandstone and conformably underlies Kiowa shale. Thickness 32.5 to 94 feet. Age is Early Cretaceous (Comanchean).
