Greater Yellowstone Coalition
The Greater Yellowstone Coalition is a conservation organization protecting the lands, waters and wildlife of the Greater Yellowstone Ecosystem of Idaho, Montana and Wyoming. The group was formed in 1983 with the idea that protecting Yellowstone and Grand Teton national parks could only be achieved by protecting the wild integrity of the last largely intact temperate ecosystem in North America. The group is based in Bozeman, Montana, and has offices in Driggs, Idaho, Jackson, Wyoming and Cody, Wyoming.
The GYC led the fight against the New World gold-silver-copper mine, which was proposed to be sited only about four miles from the northeast entrance to Yellowstone National Park, during the early 1990s.
