Mount Hesperus is the highest peak of the Revelation Mountains, the westernmost subrange of the Alaska Range. The Revelations are a small, rarely visited range, but they contain dramatic rock peaks, rising from low bases. Mount Hesperus is particularly impressive in terms of local relief: for example, it drops over 7,500 feet (2,286m) in less than 2 miles (3,219m) on two sides. Such steepness for this amount of relief makes Hesperus comparable to the best peaks in North America.
