About this map

Downieville serves as the focal point of this terrain, where the Downie River joins the North Yuba River amidst steep ridges. This 2018 survey reveals a landscape shaped by historical mining operations, notably marked by the Oxford Mill and the High Commission landmark. The settlement patterns follow the river benches, evidenced by clusters like Zumwalt Flat, Jersey Flat, and Durgan Flat.

Upland reaches are defined by a complex system of named ravines and ridges within the Tahoe National Forest, including the First Divide, Second Divide, and Third Divide. The presence of the Truckee Ditch near Table Mtn and the winding Henness Pass Rd reflects the enduring importance of water and transport infrastructure in this part of Sierra County. From the heights of Grizzly Peak to the river crossings at Ham Bar, the map documents the verticality and resource-driven geography of the Northern Sierra.
