Parker Peak (California)

Parker Peak is a 12,861 ft mountain summit located in the Sierra Nevada mountain range, in Mono County of northern California, United States. It is situated in the Ansel Adams Wilderness, on land managed by Inyo National Forest. It is approximately 7.0 mi northwest of the community of June Lake, 1.2 mi east of Yosemite National Park's eastern boundary, and 1.0 mi east of Koip Peak, the nearest higher neighbor. The mountain is visible from the June Lake Loop, and from the nearby June Mountain ski area. Topographic relief is significant as it rises over 5,700 ft above Grant Lake in four miles. The peak's name is derived from Parker Creek, which in turn was named after an early settler of Mono County. This geographical feature's name has been officially adopted by the U.S. Board on Geographic Names. The first ascent of the summit was made in 1914 by Norman Clyde.

Climate
According to the Köppen climate classification system, Parker Peak has an alpine climate. Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains. As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift). Precipitation runoff from this mountain drains into headwaters of Parker and Alger Creeks, both of which are tributaries of Rush Creek.
