Seven Devils Mining District — Rockhounding in Adams County, Idaho
Seven Devils is a classic Idaho skarn and copper district, where Idaho Geological Survey maps and reports emphasize limestone-garnet belts, copper deposits, and lime-silicate minerals. For collectors, that translates into a broader mineral suite than most Idaho sites: garnet, epidote, malachite, zoisite, and related contact-metamorphic material. Reported finds include epidote, red garnet, pink garnet, malachite, thulite, and more. Below: coordinates, access notes, nearby spots, and trip-planning links.
