2015 Map of Moccasin

About this map

The Hetch Hetchy Aqueduct cuts a strategic path through this segment of Tuolumne County, tracing the complex water infrastructure that serves distant municipalities. This 2015 survey illustrates the modern landscape around the settlements of Moccasin, Priest, and Big Oak Flat, where the steep topography of the Sierra foothills dictates the winding routes of Old Priest Grade and Priest Grade. The relationship between terrain and water management is central to the area's character, evidenced by the proximity of Don Pedro Reservoir, Moccasin Reservoir, and Priest Reservoir. Notable elevations like Moccasin Peak and the sprawling Peñon Blanco Ridge overlook historic flats and drainages including Marshs Flat and Grizzly Gulch, offering a detailed perspective on a region defined by its role in California's hydraulic history and its enduring Gold Country settlements.
