2018 Map of Penon Blanco Peak

About this map

Peñon Blanco Peak and the high ridgeline of Peñon Blanco Ridge dominate this section of the Sierra Nevada foothills on the border of Tuolumne and Mariposa counties. The landscape is defined by its relation to water, sitting between the expansive Don Pedro Reservoir to the west and Lake McClure to the south. Historically significant nodes like Granite Springs, home to the Granite Springs Cem, and the settlement at Blanchard illustrate the residential development patterns in this gold-country region. The map reveals a transition from traditional flats and gulches, such as Whisky Flat and Bonds Flat, to contemporary planned communities like Lake Don Pedro. This geographic survey preserves the names of early family-held locations and topographical landmarks like Kassabaum Flats and Jasper Point, reflecting the enduring legacy of 19th-century land use amidst 21st-century infrastructure.
