These include mines officially abandoned under MSHA oversight and past producers documented in the USGS Mineral Resources Data System. Abandoned mines are a legacy of centuries of mineral extraction and can pose ongoing environmental and safety concerns for nearby communities.
Safety Warning: Abandoned mines are extremely dangerous. Hazards include cave-ins, toxic gases, flooded shafts, unstable ground, and hidden vertical drops. Never enter an abandoned mine. Many are on private property. If you discover an unsecured abandoned mine, report it to your state mining agency.
