Pg. 361, 366. Elk Creek beds. Variable shaly and arenaceous strata composing that part of Cheyenne sandstone that overlies Corral sandstone. Divided into Stokes sandstone (a few feet thick) above and Lanphier beds (10 to 15 feet thick) below. Underlain by Corral sandstone and overlain by Champion shell bed. Age is Early Cretaceous (Comanche).
[Named from Elk Creek, Kiowa Co., central southern KS.]

†Elk Creek beds. This name was discarded by the USGS in 1921, being simply a local name for major part of Cheyenne sandstone.

Pg. 13-14. †Elk Creek beds. Elk Creek beds of Cragin were named for exposures about head of Elk Creek, the lower part being differentiated by Cragin as Lanphier beds, from exposures on Lanphier ranch about 5 miles southeast of Belvidere, where this member consists of 10 to 15 feet of poorly cemented sands containing streaks and lenses of black to gray shale. Cross lamination is extremely common in the sandstones. Fragments of lignite, crystals of gypsum (selenite), locally richly impregnated with gypsum. Another characteristic is presence of logs composed of lignite and pyrite. All parts of Elk Creek beds contain dicotyledonous plants. Writer does not consider it possible definitely to recognize any member of Cheyenne sandstone beyond limits of one locality. Cragin's divisions are considered to have no validity for more than local application, and as his 3 members were not differentiated in same section it is possible that 2 of them may be one.
