Mount Gibbs, Mountain summit in Yosemite National Park, United States

Mount Gibbs is a Sierra Nevada summit 2.6 miles (4 km) south of Mount Dana, on the boundary between Yosemite National Park and the Ansel Adams Wilderness. It reaches 3,893 metres (12,779 ft) on the line between Tuolumne and Mono Counties. The easiest ascent follows the ridge extending west from the peak, with a steep section of loose, unstable rock before the gentle summit ridge.

Mount Gibbs is named after Oliver Gibbs, a Harvard University professor and friend of Josiah Whitney, the geologist who led the California Geological Survey. The name ties the peak to the survey's circle of scientists rather than to any climbing first ascent, and no 1864 ascent is recorded in the sources.

Mount Gibbs is named for Oliver Gibbs, a Harvard University professor and friend of Josiah Whitney, the geologist who led the California Geological Survey. The name honors that personal connection rather than any geological work by Gibbs himself.

The peak can be reached from the west via Tioga Pass Road or from the east through Bloody Canyon, with both routes being relatively straightforward to hike. Visitors should prepare for sudden weather changes and start early to return before dark.

Mount Gibbs is the sixth-highest mountain in Yosemite National Park. From the summit, the view of Mono Lake is partly blocked by an outcropping to the northeast, so the lake is not fully visible from the top.
