Gannett Peak
Overview
Geographically, Gannett Peak is the apex[
Gannett is the highest peak within what is better known as the Greater Yellowstone Ecosystem and is the highest peak in the Rocky Mountains outside of Colorado. The 896-acre (3.63 km2) Gannett Glacier, which is likely the largest single glacier in the American portion of the Rocky Mountains, extends across 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 in the heart of a remote and rugged wilderness. Because of this, its elevation, and extreme weather, it is often considered by
