Gannett Peak, at 13,810 feet, is Wyoming’s highest mountain and the loftiest summit in the Wind River Range, the Greater Yellowstone Ecosystem, and the Rocky Mountains outside Colorado. Located on the Continental Divide in the remote Bridger Wilderness, its slopes reach into both Bridger-Teton and Shoshone national forests. Named in 1906 for geographer Henry Gannett, it is also notable for its great prominence and for dominating the surrounding landscape for hundreds of miles. Glaciers, especially the expansive Gannett Glacier, give the mountain a strongly alpine character. Its isolation, severe weather, glaciated terrain, and other hazards make it one of the most difficult state high points to reach.
