Locality 53. Exposures along southwest-facing bluffs of spur trending SE from center of S. line, sec. 13 into NE ¼ sec. 24, T. 20 N., R. 26 E., Little Eagle quad., Corson Co. Lower bluffs chiefly from top Elk Butte memb. into Gervilliz - layers of Trail City. Hill A. - Large “beveren” conc. layer with yellow calcite cement and a few small Solea-like cleams crops out in SW bluff of this hill. Could not centrally locate Protocruzlie conc layer below it – may not be exposed. Fossilif. concretions collected are from float coming from above “beveren” conc zone – at least one of them is. This has many P. linguiformis, abundant trummoids incl. many juveniles – looks like Morocco stuff. However it was not possible to tie this higher stuff in with the lower slump blocks of the Trail City. Some odd-bell nicolleti cones at this locality also, but none found in place. Nicollati and Gervilliz conc. layers, also the large Gervilliz-Limopsis layer distinct and collected from both in float and in place.
