Wyoming, United States
Gannett Peak is the highest peak in the U.S. state of Wyoming and straddles the boundary between Fremont and Sublette Counties along the Continental Divide.
Geographically, Gannett Peak is the apex of the entire Central Rockies; the largely continuous group of the chain occupying the states of Wyoming, Idaho and Montana. Named in 1906 for American geographer Henry Gannett, the peak is also the highpoint of the Wind River Range. The mountain slopes are located in both Bridger-Teton National Forest and Shoshone National Forest. Gannett is the highest peak within what is better known as the Greater Yellowstone Ecosystem. The 896 acres Gannett Glacier, which is likely the largest single glacier in the Rocky Mountains, flows down from the northern slopes of the mountain. Minor Glacier is situated in the western cirque of the peak while Dinwoody and Gooseneck Glaciers can be found on the southeast side of the mountain.
Gannett Peak is commonly climbed on a four to six day round-trip and is considered amongst mountaineers as second only to Alaska's Mount McKinley in difficulty of state high points. However, many climbers rank Gannett Peak behind both Mount McKinley and Montana's Granite Peak, which, in 1923, was the last state high point climbed.
