Standout malachite spots in Wyoming

Hand-picked from the full list below, with the reason each one earns a trip.

Kirwin Mine
Park County County
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.
