Mount Crocker is a remote 12,458-foot-elevation (3,797-meter) mountainsummit located on the crest of theSierra Nevada mountain range in northernCalifornia, United States.[5] It is situated in theJohn Muir Wilderness, on the boundary shared bySierra National Forest withInyo National Forest, and along the common border ofFresno County withMono County. Crocker ranks as the 291st-highest summit in California.[3]Topographic relief is significant as the north aspect rises 2,500 feet (760 meters) above McGee Creek in approximately one mile. It is nine miles northeast ofLake Thomas A Edison, and approximately 15 miles (24 km) southeast of the community ofMammoth Lakes.

This mountain's toponym was officially adopted in 1911 by theU.S. Board on Geographic Names.[5] The name was applied during a 1907–09 survey by Robert Bradford Marshall of theUSGS to honorCharles Crocker (1822–1888), an American railroad executive who was one of the founders of the Central Pacific Railroad, which constructed the westernmost portion of theFirst transcontinental railroad.[6][7] He was one of the fourrobber barons, along withMark Hopkins,Collis Huntington andLeland Stanford (also known asThe Big Four), who formed the Central Pacific Railroad. Mount Crocker is one of four peaks named after the Big Four that surrounds Pioneer Basin, the others beingMount Hopkins,Mount Huntington, andMount Stanford.
Thefirst ascent of the summit was made August 25, 1929, by Nazario Sparrea, a Basque shepherd.[8]
According to theKöppen climate classification system, Mount Crocker is located in analpine climate zone.[9] Mostweather fronts originate in thePacific 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 orsnowfall onto the range. Precipitationrunoff from the north side of this mountain drains into McGee Creek which empties atCrowley Lake, and from the south aspect toLake Thomas A Edison via Mono Creek, thenceSouth Fork San Joaquin River.
