1951 Map of Downieville

About this map

Downieville and Goodyears Bar anchor the southern reaches of this 1951 survey, situated along the North Fork Yuba River. This is a landscape defined by its deep mining heritage, showing the intricate network of claims and camps that persisted into the mid-20th century. Named sites like the Standard Mine, Oxford Mine & Mill, and Magnolia Mine (Site) reveal a region where hard-rock and placer mining shaped every drainage. To the north, the terrain rises toward Mt Fillmore and Table Rock, where remote settlements like Gibsonville, Howland Flat, and Port Wine reflect the isolated nature of high-altitude gold country operations. The map documents the persistent infrastructure of the era, including the historic Hennees Pass Road and numerous mountain ranches such as Lavezzola Ranch and Marvin Ranch, which provided vital support to the local industrial economy.
