About Grand Canyon of the Tuolumne
The Grand Canyon of the Tuolumne is a prominent river canyon situated within Yosemite National Park in California. Carved by the Tuolumne River, this dramatic gorge extends from Glen Aulin downstream to the Hetch Hetchy Valley, marking a significant geological feature within the Sierra Nevada.
Geography and Geology
Beginning at Glen Aulin, below the confluence of several creeks, the canyon's walls become steeper and the valley widens before narrowing again. Unlike the bare, sheer walls of Yosemite Valley, the Grand Canyon of the Tuolumne is characterized by steeper, V-shaped walls that are often densely vegetated. This flora includes chaparral, manzanita scrub, and oak woodland, interspersed with coniferous forests, creating a lush appearance that clings to ledges and climbs towards the rim. A key feature of the canyon is the presence of numerous waterfalls directly on the main course of the Tuolumne River, a contrast to Yosemite Valley where major falls are on tributaries. Among these is the spectacular 800-foot Waterwheel Falls, named for its distinct water plume. Further downstream, the canyon narrows significantly for less than a kilometer to form the Muir Gorge. Beyond this chasm, the canyon widens again into a broader section known as Pate Valley.
Recreation
The canyon is accessible to hikers via a trail that generally follows the Tuolumne River. This trail is noted for its challenging nature, often being steep, rocky, and difficult to traverse, particularly when detouring around the impassable Muir Gorge. The hike from Tioga Road to the Glen Aulin High Sierra Camp is approximately 10 kilometers. While areas like White Wolf campground are within day-hiking distance of the rim, descending to the canyon floor and returning is a strenuous undertaking. The wilderness between Hetch Hetchy Reservoir and the trail leading to White Wolf is considered trackless.
