Pg. 52. Indian Cave sandstone member of Towle shale. Consists of sandstone, siltstone, and locally conglomerate in part; occurs as local channel fillings that grade upward into basal part of the unnamed member of the Towle. Reported maximum thickness about 200 feet. Age is Early Permian (Wolfcampian).
Well exposed in the Indian Cave type locality in Nebraska.

Pg. 122. Permian rocks are known to be represented in Missouri by only a few exposures of massive sandstone in the northwestern corner of the state, in northwestern Atchison County. This sandstone occupies deep channels that have been cut into upper Pennsylvanian beds, and it is identified as the Indian Cave sandstone of early Permian (Wolfcampian) age. The sandstone is fine- to medium-grained, micaceous, and strongly cross-bedded. Fragments of clay-ironstone and limestone occur near the base. Casts and molds of fossil wood also occur in the rock. The sandstone has a maximum thickness of more than 50 feet in the northwestern Missouri outcrops.

Pg. 5 (fig. 2), 14, 15 (fig. 5), 20. Indian Cave channel sandstone bed of Towle shale member of Onaga shale of Admire group. Incised into Dry shale member of Stotler limestone of Wabaunsee group (Virgil). Age is considered Permian.
Best exposure in NW/4 SW/4 sec. 3, T. 13 S., R. 13 E., [along Mission Creek at Echo Cliff, about 1.5 mi southwest of Dover, approx. Lat. 38 deg. 56 min. 58 sec. N., Long. 95 deg. 57 min. 50 sec. W., Dover 7.5-min quadrangle], Wabaunsee Co., eastern KS.
Authors comment on lack of precise location of type, and mention the 20 to 25 foot-thick massive channel sandstone, very likely of Towle age, exposed in bluff overlooking Missouri River, in center sec. 9, T. 3 N., R. 17 E., Richardson Co., southeastern NE. This sandstone bluff is referred to as the Indian Caves by the local inhabitants.
