Bridger–Teton National Forest spans 3.4 million acres in western Wyoming and forms a major part of the Greater Yellowstone Ecosystem. Created in 1973 through the administrative merger of Bridger and Teton National Forests, it grew from earlier forest reserves established in the early twentieth century. Its landscape includes extensive high country, three wilderness areas, Wyoming’s highest peak at Gannett Peak, major glaciers, thousands of lakes, and the headwaters of the Yellowstone, Snake, and Green rivers. Rich plant and animal life persists across its varied elevations, while more than 2,000 miles of trails and broad road access make it one of the Rocky Mountains’ most important public wildlands.
