Standout quartz spots in Wyoming
Hand-picked from the full list below, with the reason each one earns a trip.
Atlantic City
Fremont County
Atlantic City sits in the South Pass country, where Wyoming's gold-mining history overlaps with the central Wyoming jade and agate belt.
Warm Springs
Fremont County
Warm Springs is a strong Granite Mountains-area pick because it combines Wyoming jade targets with agate, jasper, chalcedony, quartz, and silicified wood in one public-land collecting corridor.
Kemmerer
Lincoln County
Kemmerer anchors the western Green River Formation belt, where public-land outcrops and gravels can yield chert, chalcedony, jasper, silicified wood, and fossiliferous lapidary stone.
Kirwin Mine
Park 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.
