Northwest and Southwest Rockhounding: 2013
We found the most amazing mines, rocks and gold/silver/copper ores. The area we concentrated on was the Ruby (City) area, but we started our quest at the Alder mine near Twisp. This gold, silver, copper, zinc mine was mined up to the 1950's and it is a huge mine. Upper Level of the Alder Mine Near Twisp, WA.
