Nevada, United States
Mount Jefferson is the high point of the Toquima Range in north-central Nye County, in central Nevada in the western United States. It is located about 50 miles north of the community of Tonopah. Three distinct summits are located on a broad area of subalpine tundra: North Summit rises to 11814 feet, Middle Summit to 11686 feet, and South Summit to 11949 feet. During the Pleistocene, alpine glaciers eroded several cirques east of the summit plateau. The higher elevations of this section of the Toquima Range are protected as the Alta Toquima Wilderness Area.
As the high point of a range which is well separated from other ranges by low basins, Mount Jefferson has a particularly high topographic prominence of 5861 feet. This is the third greatest prominence in Nevada (after Charleston Peak and Wheeler Peak).
