White Mountain Peak, at 14,252 feet in California’s White Mountains, is the range’s highest summit, the highest point in Mono County, and the state’s third highest peak after Mount Whitney and Mount Williamson. Unlike nearly all of California’s other fourteeners, it stands outside the Sierra Nevada. Its upper slopes are marked by dark and orange scree and rock formed from Mesozoic metavolcanic rock altered by rising granite, and its strong topographic prominence highlights its dramatic rise above the surrounding landscape. The mountain also serves as a major high-altitude research center and a popular but still demanding climbing destination because of its extreme elevation and unusual road access.
