Mount Prater is a 13,471-foot-elevation (4,106-meter) mountainsummit located on the shared border ofFresno County andInyo County inCalifornia, United States.
The peak is set on the crest of theSierra Nevada mountain range, just south of thePalisades area. It is also situated on the boundary shared byKings Canyon National Park andJohn Muir Wilderness. Precipitationrunoff from this mountain drains east toTinemaha Reservoir via Tinemaha Creek, and south into headwaters ofSouth Fork Kings River.Topographic relief is significant as the summit rises 2,100 feet (640 meters) above Tinemaha Lake in one mile.
TheJohn Muir Trail, which passes below the western base of the peak, provides a climbing approach option. Thefirst ascent of the summit was made in 1928 by Alfred William Prater and his wife.[5] The North Ridge was first climbed by Fred L. Jones on October 6, 1948. "Obvious Chute" was first climbed March 19, 1972, by Ed Treacy, Karl Bennett, Dave Gladstone, Dave King, Vi Grasso and Doug Mantle.[1] "Hidden Couloir" on the East Face was first climbed by Del Johns and Wayne N. Sawka in late September 1980.[6] Inclusion on theSierra Peaks Sectionpeakbagging list generates climbing interest in this peak.
This landform's name commemorates Alfred William Prater (1902–1929), mathematics professor at University of California and the mountaineer who was first to climb this peak with his wife in the summer of 1928.[5] The toponym was officially adopted in 1930 by theUnited States Board on Geographic Names.[5]
Mount Prater is located in analpine climate zone.[7] 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.
