About this map

The mountain mining camps and early settlements of the northern Sierra Nevada characterize this late nineteenth-century survey. Downieville sits at the confluence of the North Fork and South Fork of the Yuba River, serving as a hub for the surrounding gold-bearing ridges. The landscape is a dense network of nineteenth-century infrastructure, including the Sierra Turnpike and numerous active mining sites like the Empire Mine, Keystone Mine, and Young America Mine.

Remote hydraulic and lode mining communities such as Whiskey Diggings, Howland Flat, and Poker Flat are mapped in detail, showing their proximity to the timber and water resources of the Plumas National Forest. To the north, the terrain transitions into the wider valleys of Quincy and Spring Garden Ranch. The map captures the region when small settlements like Gibsonville and La Porte were central to the local economy, long before many of these mountain camps were absorbed by the forest or reduced to foundations.
