mine claims within 30 miles of a national park site or national monument

A new analysis by the National Parks Conservation Association reveals more than 490,000 mining claims on federal public lands across the U.S., a 27% increase since 2019.

Of these, more than 120,000 claims are located within 30 miles of a national park or national monument.

More than 3,700 mine claims exist within park and monument boundaries.

NPCA has mapped hardrock mine claims on federal public lands (not including claims on private, state, or Tribal land) to reveal the scale of mining activity near some of our most iconic and vulnerable national parks.

The Threat of Mining to National Parks

25%

of mining claims on all public lands are near a national park or monument.

Our national parks are celebrated as wild and pristine places, and polls consistently show Americans across the political spectrum support protecting them. Yet mining claims still exist within national parks and monuments, and new projects are rapidly advancing across the West.

The problem lies in our outdated mining law. Passed in 1872, the General Mining Law still governs mining today, offering little oversight and leaving parks, connected waterways and wildlife habitat, vulnerable to industrial impacts.

The legacy of this outdated system is already visible, with thousands of miles of polluted waterways damaged by heavy metals. Abandoned mines, including over 38,000 abandoned land mine features inside of national parks, threaten visitor safety and wildlife, while taxpayers are left to shoulder cleanup costs.

Protecting Parks through Mining Reform

Mining must be done responsibly, ensuring that the natural and cultural resources within national parks and monuments remain fully protected. We are advocating for commonsense, bipartisan reforms that:

• Prevent new mining development within national parks.
• Place guardrails on the potential development of more than 1,000 existing mining claims within the national park system.
• Empower land management agencies like NPS and BLM to direct mining claims toward lower-conflict areas and avoid sensitive areas, including those with conservation importance.
• Fund the cleanup of abandoned mines, including those on park lands.
• Hold industry accountable for pollution and mine waste, rather than taxpayers.
• Respect Tribal sovereignty and ensure consultation early and often with Tribal communities impacted by mining.
• Ensure industry pays their fair share to communities for the minerals they extract from public lands.
