Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): Political location in record is Sweet Grass county. However, lat/long plots 150 m inside adjacent Park county. Original coordinates were: lat/long NAD27 46-2-35N 110-17-41W (46.0431 -110.2947); UTM N5098855 E554570 Z12N; PLSS line# 1: Meridian- Montana Principal, TWNSHP 003 N, RNG 011 E, Sect 06, Sect_fract NWNENE. The PLSS coordinates translate to 46.044 -110.401, 7 minutes due west of the original lat/long and 8.5 km inside Park county. The full title of the reference only mentions Park county, so the PLSS coords are probably correct. So the lat long was changed to WGS84 46.044 -110.401 and the county name was changed to Park.
Comment (Reference): The USBM publication in the reference field: USBM IC 7546, 1950, P59, is probably IC 7546 / MINES AND MINERAL DEPOSITS (EXCEPT FUELS), PARK COUNTY, MONTANA, $ 60.
