Industrial mining and timber interests define this 1930s landscape in the Plumas National Forest. The map centers on the high-altitude copper operations at the Walker Mine, featuring a detailed network including the Walker Mine Compressor, the Walker Con Mine, and an extensive Aerial Tramway system. These industrial sites are connected through the steep terrain to the Western Pacific rail line and Western Pacific Highway No 24 in the valley below.
