with it, that is probably best that can be had from poor exposures. Seems to be little possibility of tracing Stoneville facies east or NE from its area - the typical features appear to be gone by the Mercurus-Avzuce road. Might be able to get some stuff along Red Owl -> Opal roads. Stoneville facies, contrary to Seagrave, does not seem to contain much "typical Fox Hills" The locally some buff-weth. subgreywethes like those of the colgate of the Holymenutes beds. These mostly above the coal-bearing part. The facies must = Etk Butte to Colgate, or to Bull head, as it rests over Pierre with "Mobdyg" fossils. Guess as to relations Hell Cr. clay facies Hell Cr. clay facies Colo Stoneville colgate-like facies Bullhead facies TL facies Trind City Etk Butte
