Acker Peak is a summit in Yosemite National Park in Tuolumne County, California. [4] With an elevation of 10,988 feet (3,349 m), Acker Peak is the 665th-highest summit in the state of California. [5]
The summit was named for William Bertrand Acker (1859–1935), a park official. [6] This geographical feature's toponym was officially adopted in 1932 by the U.S. Board on Geographic Names. [3]
The first ascent of the summit was made July 27, 1945, by Arthur J. Reyman. [1]
Climate
According to the Köppen climate classification system, Acker Peak is located in an alpine climate zone. [7] 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 ( orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the range.
