1926 Map of Roberts Mountains

About this map

Grass Valley and the Toiyabe Range anchor this mid-1920s survey of central Nevada, a landscape defined by isolated homesteads and high-desert springs. The settlement pattern is dominated by working ranches, including Hall Creek Ranch, Brackney Ranch, and Siri Ranch, reflecting the era's cattle and sheep economy. Educational infrastructure appears as small country schools like the Grass Valley Sch and Twin Springs Sch, which served the scattered families of the Great Basin. Mining activity is preserved in the location of the Keystone Mine and Birch Creek Mine. Notable hydrological features like Dianas Punch Bowl and Spencers Hot Springs stand out against the arid expanse of the Simpson Park Mountains and Kobeh Valley. The map also captures the path of Highway 50 as it crosses the Toiyabe National Forest, providing a detailed look at travel routes through the Great Basin before major modernization.
