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.
Today, the mountain is named after Samuel Pierpont Langley. In the early 1870s, it was confused with Mount Whitney by early climbers, and called by this name. When the mistake was realized, the peak was alternately called Mount Corcoran, Cirque Peak, or Sheep Mountain; the former two names being later attached to other mountains. But its current name became established in local usage, and was made official by the Board on Geographic Names in 1943.
Mount Langley is one of the easiest of California's fourteeners to climb. A hiking trail starts at nearby Horseshoe Meadow, at an elevation of about 10,000 feet (3,048 m), passes scenic Cottonwood Lakes, and climbs through New Army Pass. From there climbers make their way across a mountain meadow and up a long gradual slope of rock and gravel before making a class 3 scramble to the summit. New Army Pass is 7 miles (11 km) from the trailhead at Horseshoe Meadow and is an easier but longer approach to Langley than Old Army Pass.
Due to the elevation, both passes are covered with snow most of the year. New Army Pass sits on a south-facing slope and it tends to clear of snow somewhat earlier in the season. Old Army Pass is only clear of snow for less than two months per year, from mid-August to early October. During the winter months, even the paved road to Horseshoe Meadow is closed, making the summit significantly harder to reach.
