The Genundewa Limestone is at an elevation around 700 Feet at Penn Dixie. No West River Shale has been found yet at Penn Dixie by Steinberg (2026). Steinberg (2026) visited the closest known rock formation to the south/souteast of Penn Dixie along the I-90 just north of Hilbert College which was at the 700-730 elevation. This was a shale that Rockd called Cashaqua/Middlesex Shales. Could this be West River Shale?
Otto Muller calls it Rhinestreet Shale.
