Mount Langley is located on the crest of the Sierra Nevada, on the boundary between Inyo and Tulare counties, in eastern California in the southwestern United States. To the east is Owens Valley, and to the west is the Kern River Valley. It is the ninth highest peak in the state and the seventh highest in the Sierra. Mount Whitney, the highest peak in the contiguous United States, lies 4.8 miles (7.7 km) to the northwest. The National Geodetic Survey benchmark on the summit gives an elevation of 14,042 feet, and this is the elevation shown on the Lone Pine 15" quadrangle published in 1946 and cited by many authors.
