Mine Info

Satelite View

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.

Comments

Comment (Development): THIS PROPERTY CONSISTS OF 10 UNPATENTED CLAIMS, TWO MILL SITES AND TWO WATER RIGHTS (IN 1911)

Comment (Location): Political location in record is Mineral county. Lat/long plots in Missoula county. Original coordinates for line#1 were: lat/long NAD27 47-15-24N 114-46-33W (47.25667 -114.77583); UTM N E Z; PLSS line# 1: Meridian- Montana Principal, TWNSHP 017N, RNG 026W, Sect 01, Sect_fract . PLSS coordinates center of section 1 plot at 47 15 40N, 114 51W which agrees very closely with the relative position description of 3.5 MI SE OF KEYSTONE PEAK. Original lat/long agree with the location comment "JUST WEST OF GLEN METALS PROPERTY". However, 10094314 Glen Metals Mining Co. Mine also had a disagreement between lat/long and county name and was likely misplotted. MRDS contains two more mines said to be in the the Carter district. They lie 4 km WNW and 2 km SSW of the PLSS location. Geonames has no entry for Carter in Mineral or Missoula counties. These two other Carter district mines have agreement between the PLSS, lat/long, and county name fields. So it is likely the PLSS coordinates for this mine and the Glen Metals mine are correct, so they were used to create new lat/long coordinates in the SE part of section 1.

Comment (Location): JUST WEST OF GLEN METALS PROPERTY.
