Main image

White Mountain Peak is the highest summit of the White Mountains in eastern California, United States, with an elevation of about 14,252 feet (4,344 metres). It is a prominent fourteener separated from the Sierra Nevada to the west.

The mountain is commonly climbed by hikers using a long but non-technical route that follows a maintained dirt service road for much of the ascent; the approach is high and can be used for altitude acclimatization. The slopes host high-altitude research facilities that have been used for physiological and atmospheric science.

White Mountain Peak has been used for scientific research and mountain recreation over the 20th and 21st centuries; the presence of research stations and service roads reflects that dual use. The area around the peak is managed for both access and protection of alpine environments.

The peak stands in the White Mountains of eastern California, east of the main Sierra Nevada crest and within the Inyo/Mono region of the state.

  • Elevation: Summit elevation is 14,252 feet (4,344 metres), making it the highest summit of the White Mountains of California.
  • Access: A rough service road reaches high on the mountain, enabling non-technical ascent to the summit in summer conditions.

What to See #

  • Barcroft Research Station: A high‑altitude research facility run by the University of California located on the mountain's slopes, used for physiological and atmospheric studies.
