MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

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.
