About this map

Hetch Hetchy Reservoir dominates this portion of Yosemite National Park, where the waters of the Tuolumne River are impounded within the famous Hetch Hetchy Valley. The terrain rises sharply from the reservoir floor to landmarks like Le Conte Point and the towering Smith Peak. To the east, the Grand Canyon of the Tuolumne River reveals the dramatic glacial carving of the Sierra Nevada.

Hydrological features define the high country, including Harden Lake and the drainage systems of Tiltill Cr and Rancheria Cr. The map highlights the juxtaposition between the deep waters of the reservoir and the surrounding meadows and valleys, such as Smith Meadow and Tiltill Valley. Natural water features like Rancheria Falls and Breeze Cr illustrate the complex network of tributaries feeding into the Tuolumne system within this protected wilderness area.
