upon Pierre shales. East of there, in about the NW cor of NW ¬ NE ¬ Sec 8, Tp. 1 N, R. 70 W., we found a sandstone much resembling the Hygiene, dipping SE but dip slight, on N face of mesa. Found a few fragments of Ostrea Ostrea and Inoceramus Inoceramus, undeterminable, former turned up sharply at sides and attached to the latter, much resembling O. congesta Ostrea congesta from the Niobrara. This may be the equivalent of the sandstone in the pasture NE of Haystack Butte Haystack Butte, Colorado, as well as the one found by us today in the SE corn of NE ¬ NE ¬ or NE cor SE ¬ NE ¬ sec. 7 Tp 1 N., R. 70 W in N edge of gulch near E line of section. This supposition would make it strike nearly the same as the underlying Hygiene sandstone.
