1929 Map of Roberts Mountains

About this map

Roberts Mountains and the surrounding high basins of central Nevada are documented here in the late 1920s, showing a landscape defined by isolated ranching outposts and mineral extraction. The map reveals a network of family-held properties such as the Siri Ranch, Sadler Ranch, and Brackney Ranch situated near vital water sources like Shipley Hot Springs. These springs, including Spencers Hot Springs and Potts Hot Springs, were essential anchors for settlement in the arid Kobeh Valley and Garden Valley. Industrial activity is marked by the Keystone Mine in the northern ranges and the Birch Creek Mine to the west. The social infrastructure of these remote districts is evidenced by several rural schoolhouses, including the Grass Valley Sch and Twin Springs Sch, which served the scattered population before modern consolidation.
