Loc. 47 Crawford Reach: Toe of spur just east of Little Eagle road in center E 1/2 E 1/2 NW 1/4 sec. 13, T. 19 N, R. 26 E., the next spur N along road from Loc. 46. No good exposures here but an abundance of fossiliferous cones. from lower Trail City are weathering out of lower part of spur. Various parts of spur do not hang together stratigraphically and are probably successive slumps. Locations 46 and 47 appear to contain both individual PB and Gervillia cones and cones in which the two types of accumulation are joined in single large cones. A very few cones with dominance of Pteris nebraskensis and Probecordia in float. The Timber Lake beds and concretions above the lower spurs appear unfossiliferous here - similar to section at Bullhead, what governs distribution of the Timber Lake marine fauna? 21
