Pg. 6, fig. 1. Flint Hill sandstone in Little Osage member of Fort Scott formation. Channel type sandstone and siltstone that occurs above Blackwater Creek shale in Little Osage member and below Higginsville limestone member. Name credited to A.G. Unklesbay. [Age is Middle Pennsylvanian (Desmoinesian).]
[Greene and Searight state type section is in NW/4 SE/4 sec. 11. Thompson and Gentile (2004) state type appears to be a composite of 2 sections: (1) upper part measured in west bluff of small stream in SW/4 SW/4 sec. 11; (2) lower, and best section, in roadcuts on south side MO Highway 124 in center W/2 SW/4 sec. 11.]

Pg. B177-B178, Appendix B. Flint Hill sandstone facies (informal) in Blackwater Creek Shale Member of Little Osage Formation of Fort Scott subgroup [informal] of Marmaton Group. Ranges from a sandstone to a calcareous silty sandstone, and grades laterally into the shale of the Blackwater Creek Member. It has also channeled downward through much of the Blackwater Creek Member in many places, and may even have cut out the Houx Limestone Member and at least part of the Binkley Shale Member. Often regarded as a separate member of the Little Osage Formation, we consider the Flint Hill to represent a lateral accretionary sandstone deposit in a fluvial-delta-plain environment within the Blackwater Creek Shale Member. Age is Middle Pennsylvanian (Desmoinesian).
