About this map

Don Pedro Reservoir dominates the western landscape of this Tuolumne County survey, where the rising waters meet the foothills of the Sierra Nevada. The infrastructure of the Hetch Hetchy Aqueduct is visible cutting across the terrain, a critical component of the regional water system that links high-country resources to distant urban needs. Near the center of the sheet, the settlement of Moccasin sits below Moccasin Peak, serving as a hub for the local water and power operations.

Gold Rush era history is evidenced by the proximity of Big Oak Flat and the McAlpine Mine, while the steep climb to Priest illustrates the challenging topography of the Mother Lode country. Along the Penon Blanco Ridge and through Grizzly Gulch, the map reveals a landscape shaped by both extractive industry and massive engineering projects, including the Moccasin Res and the nearby Priest Reservoir with its notable Spillway.
