Gemini (California mountain)
Gemini is a 12,880-foot-elevation (3,926 meter) twin-peaked mountain summit located west of the crest of the Sierra Nevada mountain range in Fresno County of northern California, United States. It is situated in the John Muir Wilderness, on land managed by Sierra National Forest. It is set west-southwest of Merriam Peak, and southeast of Seven Gables, the nearest higher neighbor. Topographic relief is significant as it rises over 3,500 feet (1,067 meters) above Piute Canyon in approximately three miles. Gemini ranks as the 176th highest summit in California. History. The first ascent of the  summit was made July 30, 1953, by Jim Koontz and Rosemarie Lenel. The mountain's name was suggested by Chester Versteeg, a prominent Sierra Club mountaineer from Los Angeles. The peak's name was officially adopted in 1954 by the U.S. Board on Geographic Names and promulgated in 1957. Today this peak draws climbing interest because it is included on the Sierra Peaks Section's peak bagging list. Climate. According to the Köppen climate classification system, Gemini is located in an alpine climate zone. 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 tributaries of the South Fork San Joaquin River.
