Comment (Location): County name is Jefferson. However, original lat/long plots in Powell county. Original coordinates were: lat/long NAD27 46-18-11N 112-55-0W (46.3031 -112.9167); UTM N5129287 E352397 Z12N; PLSS line# 1: Meridian- Montana Principal, TWNSHP 006 N, RNG 003 W, Sect 01, Sect_fract NE. PLSS coordinates translate to 46.304 -111.916, exactly 1 degree longitude east of original lat/long and in Jefferson county. It is likely the reporter mistyped the longitude so it was changed to -111.9167.
