Comments
Comment (Location): Political location in the record is Beaverhead county, Montana. However, the lat/long plot in Lemhi county, Idaho according to the MAPINFO county coverage. The original coordinates were: lat/long NAD27 45-16-43N 113-40-45W (45.2786 -113.6792, WGS84 45.27646 -113.6792); UTM N5017176 E289860 Z12N; PLSS line# 1: Meridian- Montana Principal, TWNSHP 006 S, RNG 017 W, Sect 27, Sect_fract NESWSW. The PLSS coordinates convert to WGS 45.282 -113.679, falling more solidly in Beaverhead county. Recalculating the lat/long using WGS84 datum gives 45.2785 -113.6792, very close to the PLSS coordinates. So the lat/long coordinate were changed to agree with the PLSS coordinates.
