Satelite View

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

Comment (General): It appears that this record is just a report that some tungsten has been reported in the district. There are no scheelite mines or prospects. "Scheelite has been found on the dumps of the Amanda, Hidden Hand, and Iron Duke mines (Bull. 50, p. 201)" in the Lewiston District.

Comment (Commodity): Tungsten is not mentioned in Armstrong's 1948 OFR.
