Locality 54 - Southwest-facing bluffs of spur trending SE through S1/2 sec 18 and joining terrace NE Little E2yle in NE1/4 sec. 19, T. 20 N., R. 27E. Chief exposures are in E1/2, SE1/4, SW1/4 and S1/2, SW1/4, SE1/4, sec. 18, and NW corner. NE1/4 NE1/4 sec. 19. Problem of nicolleti concretions here. Some concretions of uncertain position in slope contain fauna featuring abundance of D. nicolleti, but also elements such as "corundi" tribe which elsewhere appear first in PB conc. layer or large G.-P.B. Possibly these odd D. nic concs are higher than the lower D. nic layer but occur lower than PB horizon. Need some short sections here to try to resolve this. The odd-ball concs are different core-type than usual D. nic concs.- a harder, bluer limestone lacking the thick silt jackets. Partial sections at fence exposure:- A. About 20' west of fence, beginning at base of Trail City on jerosite streak with 15 concs- elongate- having thick, laminated to thin-bedded 48
