About this map

The Tuolumne and Mariposa County line divides this landscape of high ridges and significant water storage projects. In the north, the Peñon Blanco Ridge rises above Herbeck Flat, with Peñon Blanco Peak serving as a dominant landmark. The terrain is marked by numerous gold-era canyons such as Ned Gulch, Spring Gulch, and the curiously named Picture Gallery Gulch. Settlement patterns are concentrated around localized flats and former mining sites, including Whisky Flat and Blanchard.

Infrastructure in this 2015 survey reflects the importance of the region's reservoirs, with the vast Don Pedro Reservoir in the northwest and Lake McClure in the south. Local history is grounded in sites like the Granite Spring Cemetery and remnants of industrial access like the Solambo Mine Rd. The network of residential roads near Granite Springs and Bonds Flat illustrates the modern habitation of these historic foothills.
