The Tuolumne and Mariposa County line divides this landscape of steep ridges and reservoir shorelines. Small settlements like Blanchard and Granite Springs anchor a network of rural roads, including Black Jack Mine Rd and Solano Mine Rd, which point to the region's mining heritage. The topography is dominated by the Penon Blanco Ridge and the Oat Hills, falling away toward the massive water bodies of Don Pedro Reservoir and Lake McClure.
