Summary:
Pg. 22, 236, etc. Dry shale of Wabaunsee group. Dry shale is here applied to shaly beds, 5 to 20 feet or more thick, that separate Dover limestone from next higher (Grandhaven) limestone. Is bluish gray and for most part clayey, but sandy beds appear in places. In southern Kansas a thin coal occurs near top. Is well-defined unit from Shawnee County, eastern Kansas, south to Oklahoma line, but to north it coalesces with Friedrich shale above and Grandhaven limestone, which disappears, although it is possible the Grandhaven beds grade laterally into the shale. Where the shale between Dover and Jim Creek limestone cannot be subdivided it may be called [/]Dry-Friedrich shale. Age is Late Pennsylvanian (Virgil).
Type locality: Dry creek, southwest of Emporia, in sec. 5, T. 20 S., R. 11 E., [Lyon Co.], eastern KS.
[GNC remark (ca. 1936, US geologic names lexicon, USGS Bull. 896, p. 635): This name appears to have first appeared in print, without definition, in a table by R.C. Moore published opp. P. 14 of Univ. Kansas Bull., no. 20, May 1, 1935.]
