Mount Lyell

Mount Lyell is the highest point in Yosemite National Park, at 13,114 feet . It is located at the southeast end of the Cathedral Range, 1.2 miles northwest of Rodgers Peak. The peak as well as nearby Lyell Canyon is named after Charles Lyell, a well-known 19th century geologist. The peak had one of the last remaining glaciers in Yosemite, Lyell Glacier. The Lyell Glacier is currently considered to be a permanent ice field, not a living glacier.
Mount Lyell divides the Tuolumne River watershed to the north, the Merced to the west, and the Rush Creek drainage in the Mono Lake Basin to the southeast.

The most common approach to Mount Lyell is from Tuolumne Meadows on a highly traveled section of the John Muir Trail. The round trip is approximately 25 miles and involves 4,500 feet of elevation gain when starting from the Tuolumne Wilderness Office. The hike is easy from Tuolumne Meadows, following the Tuolumne River to the head of the Lyell Canyon, and becomes moderate as it approaches Donohue Pass. Before reaching Donahue Pass, the route leaves the trail and heads south towards Mount Lyell.
