Alaska Tribes Stop North America's Largest Mine

The world's largest sockeye salmon run just got a powerful safeguard, thanks to Indigenous communities who refused to let their homeland become a mining site.

In 2001, a Canadian mining company proposed building North America's largest open-pit mine at the headwaters of Bristol Bay, Alaska. The Pebble Mine would have sat at the connected headwaters of the region's two major river systems, storing tens of billions of tons of toxic waste in an earthquake-prone zone.

For the Yup'ik, Dena'ina, and Alutiiq peoples who have stewarded these lands for thousands of years, the answer was clear from the start. They united to protect their home.

Alannah Hurley, executive director of the United Tribes of Bristol Bay, describes the region as paradise where you can still drink directly from rivers and lakes. The pristine waters support more than just salmon—they sustain entire communities through fishing that generates $2 billion annually and provides cultural and spiritual nourishment.

The tribes understood what was at stake. "Anything that happens to our lands and waters happens to us," Hurley explains. The proposed mine would have devastated the watershed in an area where everything from salmon to caribou to people remains deeply interconnected.

After more than two decades of advocacy, organizing, and resistance, the Indigenous coalition achieved something remarkable in 2023. They secured an EPA veto of the Pebble Mine project, one of the rarest environmental protections the agency can grant.

The victory preserves one of Earth's last pristine ecosystems. Bristol Bay's waters remain so clean that locals can drink straight from them, and its lands continue producing food the traditional way.

The Ripple Effect

This win extends far beyond Bristol Bay's borders. It proves that Indigenous-led conservation can stop even the most powerful mining interests when communities unite around protecting their homeland.

The recognition continues growing. Hurley just received the 2026 Goldman Environmental Prize for North America, honoring her leadership in this historic fight. But the real prize is simpler: future generations will inherit the same paradise their ancestors knew, where rivers run clean and salmon return home every year.

The tribes didn't just save a fishery—they protected a way of life that has sustained their people for millennia and will continue for millennia more.
