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 (Location): Political location in record is Missoula county. However, lat/long fall just inside adjacent Granite county. Original coordinates were: lat/long NAD27 46-48-17N 113-27-14W (46.8047 -113.4539); UTM N5186169 E312760 Z12; PLSS line# 1: Meridian- Montana Principal, TWNSHP 012 N, RNG 015 W, Sect 04, Sect_fract C S2SW. Leonard is shown on the Union Peak topo sheet. Geonames lat/long is NAD83 46.8049303 -113.4545270 (464818N 1132716W). The location was changed to the Geonames coords because they coincided with the topo sheet and visible workings in Google Earth. Incidentally, if the original lat/long is recalcalculated using WGS84 it falls only 50m SW of the new coordinates. The original PLSS coords fall a full 4 km NW of the location shown on the topo sheet. The were changed to the new coords simply by switching the section from 4 to 11. The UTM coords agreed with the original lat/long so they were cleared.
