Locality 52 - Northwest-facing bluffs of spur in SE1/4, SW1/4 sec. 5, T. 19 N., R. 27 E., Little Eagle quad., Carson Co., and their extension into a narrow gulley just over the south line into section 8. Collections from two principal parts of these bluffs, those labelled 52 are chiefly from the exposure on the NE side of the narrow gulley in section 8, those labelled 52A are from an amphitheatre-shaped exposure at opposite end of locality in NE1/4, SE1/4 SW1/4 sec. 5. At this latter place several of the Upper Nicolleti concs found in place and in float. The section exposed is similar to that measured at locality 51A, but not quite as much is exposed. The upper D. nicolleti layer seems unusually well represented by concretions in the area of localites 51 and 52.
