1929 Map of Roberts Mountains

About this map

Roberts Mountains dominate this central Nevada landscape, rising between the expansive Kobeh Valley and Garden Valley. In the mid-1920s, this region was a network of high-desert ranching and mineral extraction, centered around reliable water sources like Shipley Hot Springs and Sulphur Springs. The map reveals the early importance of the Lincoln Highway, which traverses the basin near Twin Springs, providing a vital transit corridor through the Simpson Park Mountains. Family-run operations are documented through numerous named homesteads, including the Roberts Creek Ranch and Siri Ranch. Mining activity is anchored by the Keystone Mine in the north and the Birch Creek Mine near the edge of the Toiyabe National Forest. Local education is also represented, with rural institutions such as the Sadler Sch and Grass Valley Sch serving these remote ranching communities.
