Mount Humphreys, Mountain summit in Sierra Nevada, United States

Mount Humphreys is a granite summit in the Sierra Nevada of California, rising to about 13,986 feet (4,263 m) with steep faces on multiple sides. Several climbing routes reach the top, varying in difficulty from moderate to very demanding.

The peak was named in 1873 by the California Geological Survey after Andrew A. Humphreys, who served as chief engineer of the United States Army. He had no known personal connection to the Sierra Nevada, and the name was purely a tribute to his work.

Mount Humphreys is one of fifteen Emblem Peaks in California, a group of summits recognized by the Sierra Peaks Section as notable climbing goals. Reaching the top is considered an achievement within the California mountaineering community.

The standard approach to the mountain goes through Piute Pass, after which the final ascent requires technical climbing ability and appropriate gear. Conditions are most manageable in summer, once snow has cleared from the upper routes.

Mount Humphreys is the highest peak in the Bishop area and the 13th highest in California, yet it falls just short of the 14,000-foot mark, making it the state's highest peak that is not a fourteener. Its first recorded ascent was made in 1906 by Edward and James Hutchinson.
