49 Tribes, and the park draws millions of visitors each year who come to witness awe-inspiring lands and iconic wildlife. People who love Yellowstone come from all nations, political affiliations, and backgrounds.
At GYC, we see firsthand the power of Yellowstone to bring people together. One of our core principles is to work with all people to protect the lands, waters, and wildlife of the Greater Yellowstone Ecosystem. Alongside activists, ranchers, scientists, politicians, business owners, and everyday community members, we have fought and won campaigns against toxic mining proposals that would have forever altered the face of Yellowstone if they had been allowed to proceed.
When President Clinton (D) came to the region in 1996 to mark the victory against the New Word Mine proposed near Cooke City, Montana, he coined the phrase “Yellowstone is more valuable than gold.” For years, the threat of toxic mine waste loomed over the Yellowstone River and its Wild and Scenic tributary, the Clarks Fork. Stopping the mine was hard work, but our dogged approach showed the power of a group of passionate people who just won’t quit. After all, everyone involved knew that Yellowstone was worth the fight.

Two decades later, mining proposals again galvanized local communities and led to Sally Jewell, Secretary of the Interior during the Obama Administration, enacting a two-year ban on mining north of Yellowstone. This was followed up in the next administration by Secretary of the Interior Ryan Zinke enacting a 20-year ban. At the time, he was quoted as saying, “I love hard rock mining, but there are places to mine and places not to mine.”
In 2019, GYC, National Parks Conservation Association, Park County Environmental Council, and local business leaders united to advocate for the Yellowstone Gateway Protection Act. With bi-partisan support from Montana Senators Jon Tester (D) and Steve Daines (R), and Representative Greg Gianforte (R), President Trump (R) signed the act into law, permanently protecting 30,370 acres of public land north of Yellowstone from gold mining.

Yellowstone has the power to unite, even in times of deep division. GYC is committed to working with all people who care about this region, now and in the future.
