Tensleep. At Tensleep, interval of units 1 to 4 is quite variable. Possibly only unit 4 is represented by leusing tabular ss. Unit 5 rep. (possibly) by rather thick czvb silt siltsm which is in sharp contact with waxy clstm = to unit 6. Polished pebbles begin within 2 ft. t of contact. Here units 1-4 prob = Greybull. Unit 9 equiv. present but beneath verrecized clstns then platy carb silts. No basal cht pob. can seen. Morrison contact in doubt, Hyettville Probable equiv of units 1-4 down tudy, incl. fairly massive ss holding hogbeck (Check this to See whether green silt in the interval) Unit 5 is quite thick, as at Tensleep, lies in slope. basal few feet platy silts. Unit 6 waxy clstm. Units 6-8 fairly thick. Unit 9 present but broken by interbeds of siltsm & clayey stuff, commonly carb. 15.
