Greater Yellowstone

fishing-henrys-trtThe Greater Yellowstone Ecosystem (GYE)

Located at the convergence of Idaho, Montana, and Wyoming, the GYE’s 26.8 million acres constitute one of the last largely intact ecosystems in the northern temperate zone.

Located around Yellowstone National Park and Grand Teton National Park, the GYE is internationally recognized for its geothermal geyser basin, migratory elk herds, world-class trout fisheries, grizzly bears, and free-ranging bison. This region also contains the headwaters of three major river systems: the Snake, Green and Yellowstone rivers.

With the reintroduction of the gray wolf in 1995, representatives of all mammal species present at the time of European settlement can be found in GYE—a claim that can be made by no other region in the continental United States.
