Mount Lyell

Mount Lyell reaches an elevation of 13,114 feet, standing as the highest point within Yosemite National Park and spanning across Madera and Tuolumne Counties.

The mountain received its name in honor of Charles Lyell, a Scottish geologist who made substantial contributions to geological understanding during the 19th century.

The peak forms part of the Sierra Peaks Section Peaks List and serves as a watershed divide between the Tuolumne River, Merced River, and Rush Creek drainage.

Climbers access Mount Lyell through routes starting at Tuolumne Meadows, requiring technical climbing skills and proper equipment for the challenging ascent.

The former Lyell Glacier, once a living glacier on the mountain's northern face, has transformed into a permanent ice field due to climate changes.
