About this map

Washington sits at the heart of this survey along the South Yuba River, serving as a focal point for a landscape defined by historic water management and mining infrastructure. The map details the complex hydraulic history of the region, showing the routes of the S Yuba Canal and the Cascade Canal, alongside landmarks like the Dutch Flat Tunnel near the southern border. High-altitude settlements and camps such as Relief, Omega, and Excelsior are connected by a network of specialized routes, including Rose Mountain Mine Rd and the Omega MC Trail.

The rugged terrain of the Tahoe National Forest is clearly delineated, with notable landforms like Chalk Bluff Ridge, McGuire Mtn, and Negro Jack Hill rising above the deep drainages of Steephollow Cr and Greenhorn Cr. For genealogists and historians, the precise location of named flats and ridges like Skillman Flat and Burlington Ridge provides a clear view of the area's geography as it appeared in the late 2010s.
