Comment (Location): Political location in record is Jefferson county. However, original lat/long plots 130 m inside adjacent Powell county. Original coordinates were: lat/long NAD27 46-18-40N 112-33-24W (46.3111 -112.5567, WGS84 46.30896 -113.5467); UTM N5129574 E380138 Z12N; PLSS line# 1: Meridian- Montana Principal, TWNSHP 006 N, RNG 008 W, Sect 01, Sect_fract NENENW. The PLSS coords are at WGS84 46.30896 -113.5467, the same latitude, but 0.01 degrees east. This point falls in Jefferson county and is in the midst of 5 other MRDS Leadville District records. So the lat/long was changed to agree with the PLSS coordinates, county name, and district name.
