1949 Map of Alleghany

About this map

The settlement of Alleghany serves as the focal point for this 1949 survey, which captures the Sierra Nevada gold country as the era of large-scale hard-rock mining was transitioning. The map details a landscape carved by the Middle Fork Yuba River and the rugged divide between the Tahoe National Forest and Plumas National Forest. Local history is deeply embedded in the numerous "flat" sites, including Chips Flat, Minnesota Flat, and Orleans Flat, which indicate the locations of earlier hydraulic or placer mining camps.
