1992 Map of Lake Eleanor

USGS Topo · Published 1995

About this map

O'Shaughnessy Dam anchors this high-elevation wilderness landscape, holding back the massive Hetch Hetchy Reservoir within the bounds of Yosemite National Park. This early 1990s provisional survey illustrates the rugged hydrological network of the Tuolumne River watershed, including Lake Eleanor and the dramatic vertical drops of Wapama Falls and Tueeulala Falls. Human presence is largely confined to infrastructure and seasonal outposts such as the Miguel Meadow Ranger Station, Mather Ranger Sta, and the Evergreen Lodge near the southern boundary. The map captures the intersection of managed water resources and protected wilderness, showing topographic landmarks like Kolana Rock and Hetch Hetchy Dome that tower over the granite-carved Poopenaut Valley.
