About this map

Yosemite National Park and the Stanislaus National Forest converge in this high-country landscape, defined by the major water management systems of Northern California. The map shows the significant footprint of the Hetch Hetchy Reservoir and Lake Eleanor, critical components of regional infrastructure. Steep granite landmarks like Hetch Hetchy Dome and Kolana Rock flank the deep glacial valley, while Tueeulala Falls and Wapama Falls highlight the dramatic verticality of the Grand Canyon of the Tuolumne River.

A network of historical trails, such as the Miguel Meadow Fire Road Trl and Poopenaut Valley Trl, provides access to interior meadows like Miguel Meadow and Smith Meadow. The course of the Tuolumne Wild and Scenic River carves through the center of the sheet, illustrating the transition from wilderness watercourses to managed reservoirs. This modern survey captures the enduring geography of the Sierra Nevada's western slope, where early 20th-century dam projects forever altered the natural basin.
