Mount Henry is a 12,196-foot-elevation (3,717-meter) mountain summit located in the Sierra Nevada mountain range, in Fresno County of northern California, United States.[3] It is situated on the Le Conte Divide, along the shared boundary of John Muir Wilderness and Kings Canyon National Park, and 3.7 miles (6.0 km) northwest of Emerald Peak, the nearest higher neighbor. Topographic relief is significant as the east aspect rises 3,800 feet (1,200 meters) above South Fork San Joaquin River in two miles. The John Muir Trail passes to the northeast, providing an approach option.
Etymology
[edit]The peak's name was applied in 1904 by Joseph Nisbet LeConte to honor Joseph Henry (1797–1878), an eminent American scientist noted for his investigations of electromagnetism, and who served as the first Secretary of the Smithsonian Institution.[5] This geographical feature's name has been officially adopted by the United States Board on Geographic Names.[3]
Climate
[edit]According to the Köppen climate classification system, Mount Henry 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 into the San Joaquin River watershed.
