Kirwin Mine — Rockhounding in Park County, Wyoming
Kirwin is the strongest metallic-mineral contrast to Wyoming's agate and wood localities, with USGS work documenting the district's copper, gold, lead, zinc, molybdenum, and silver mineralization. The specimen suite, including chalcopyrite, galena, sphalerite, pyrite, quartz, azurite, and malachite, makes it a focused historic mining-district stop rather than another chalcedony field. Reported finds include azurite, barite, chalcopyrite, cuprite, galena, and more. Below: coordinates, access notes, nearby spots, and trip-planning links.
