Resume Gov't (zuyou area. Skull Cr. - Besel part has bentonite which may turn out to be good marker. Local abundance fish & reptile bones may not be typical over large area, but similar bones in Ceville quad -- & Hot Springs S.D. (see spec.) also the plesiosaur from N. Colo in this approx position. Fall River - Locally much steadier than in most other parts of area, more evidence of burrowing organisms. The upper "vermicated" zone doesn't seem to be evident here, nor does shale zone common above besel ss on Jayou Kare Cr. present. Lakote. Believe only part of it is exposed & that red claysstone besel part section are Lakote. Set up like that on Robinson-Theobald sect. Jayou Kare Cr. with uppermost ss coming in, but here some grey clst between it & Fall R. contact. Should get more info on cross cutting of massive SS near top Fall Riv.
