White Mountain Peak (or simply White Mountain), at , is the highest peak in the White Mountains of California, the highest peak in Mono County, and the third highest peak in the state after Mount Whitney and Mount Williamson. It is the fourteenth most topographically prominent peak in the contiguous United States. White Mountain Peak is one of only two fourteeners (peaks above 14,000 feet) in California that are not in the Sierra Nevada, the other being Mount Shasta at the far northern end of the state in the Cascade Range. It is the only fourteener in the contiguous United States that is not in the Rocky Mountains, the Cascade Range, or the Sierra Nevada. It is in the Inyo-White Mountains. Research Station The University of California operates the White Mountain Research Center, comprising three high altitude research stations, on the mountain: Crooked Creek Station at , Barcroft Station at , and a small hut at the summit. The effects of altitude on physiology are studied at the Barcroft Station and summit hut. Climbing There is a winding dirt road leading to the summit station that is usually cleared of snow between late June and September. Access is restricted to hikers only by a locked gate about 2 miles before Barcroft Station, but White Mountain Research Station usually opens this locked gate at once each year. Open gate days are typically held on a Sunday in the summer season. The round-trip hike from the gate to the summit is about with less than of vertical gain. However, there are two different dips in the trail of about 250 feet each, adding up to a total elevation gain during the roundtrip of over 3500 feet. The open gate shaves about and of gain off the round trip. This route is popular with mountain bikers. While the peak is arguably California's easiest fourteener via the jeep road, it features more strenuous climbs such as its western ridge, an climb out of Owens Valley via a steep ridge from the end of a rough road. Another route from the East, up Wyman Canyon from the Deep Springs Valley, has a lot of water sources in the first 12 miles. It climbs 7,100 feet to the summit. The peak is rarely approached from the north where it is guarded by a narrow arête or knife-edge ridge. A better nontechnical alternative to the jeep road
