Feather Peak is a 13,240-foot-elevation (4,036 meter) mountain summit located west of the Royce Lakes in the Sierra Nevada mountain range in northern California, United States.^[3] It is situated in Fresno County, in the John Muir Wilderness, on land managed by Sierra National Forest. It is set 3.2 miles (5.1 km) east-northeast of Seven Gables, and 0.66 miles (1.06 km) northwest of Royce Peak, which is the nearest higher neighbor.^[1] Feather Peak is the 99th highest summit in California.^[4] The first ascent of the summit was made in July 1933 by David Brower, who also named this peak.^[5]

Climate

According to the Köppen climate classification system, Feather Peak is located in an alpine climate zone.^[6] 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 south into tributaries of the San Joaquin River.
