1956 Map of Lake Eleanor

About this map

Yosemite National Park and Stanislaus National Forest converge on this mid-century survey, dominated by the massive water engineering of the Hetch Hetchy Reservoir and Lake Eleanor Reservoir. The landscape is defined by the steep drainage of the Tuolumne River and its multiple forks, which are harnessed by the Hetch Hetchy Aqueduct. Human presence in this wilderness is marked by early high-country outposts like Mather, Evergreen Lodge, and the Five Star Mine. Historic travel routes, including the Tioga Road and the Old Big Oak Flat Road, trace the topography across Crocker Ridge toward the Big Creek Basin. Scattered throughout the forest are numerous specialized camps and ranger stations, such as Columbia Camp, Tuolumne Camp, and the Lake Eleanor Ranger Station, reflecting the area's dual roles in resource management and recreation.
