About this map

Hetch Hetchy Aqueduct infrastructure dominates this portion of Tuolumne County, marking the vital water conveyance system as it passes near the settlement of Moccasin. The landscape is defined by significant hydraulic works, including the Moccasin Reservoir and Priest Reservoir, which serve as key nodes in the region's managed water network. Historically significant transport routes are evident through the steep terrain, notably the Priest Grade and the Old Priest Grade, reflecting the engineering challenges of connecting the Central Valley to the Sierra Nevada foothills.

To the east, the community of Big Oak Flat sits at the edge of the survey, a long-standing gateway to the high country. The massive footprint of the Don Pedro Reservoir occupies the western and northern reaches, where flooded canyons like Kanaka Creek highlight the transformation of the river systems into large-scale storage basins. The presence of numerous named peaks and ridges, such as Domingo Peak and Peñon Blanco Ridge, provides a framework for understanding the topographic isolation of historical flats like Marshs Flat.
