Hydraulic mining scars define this segment of the Sierra Nevada foothills, most notably at the Alpha Diggings and Omega Diggings near the eastern edge. The town of Washington sits deep in the canyon of the South Fork Yuba River, serving as a focal point for the surrounding ridge-top communities and resource extraction sites. The landscape is a network of historical water management and industrial remains, including the Yuba Canal and the Towle Mill Site.
