USGS Topo · Published 1976

About this map

Malakoff Diggings and the surrounding hydraulic mining landscape dominate the northern reaches of this survey in Nevada County. At the height of post-war revision, the map details a complex water management system essential to the region's industry, including the Snow Ditch, Blue Ditch, and the extensive Cascade Canal network. The terrain is defined by prominent ridges like San Juan Ridge and Washington Ridge, which channel the South Yuba River through deep canyons.
