1929 Map of Roberts Mountains

About this map

Toiyabe National Forest dominates the rugged central highlands of this Nevada survey, an area defined by its remote ranching outposts and mineral prospects. The landscape is a series of high desert basins, including Diamond Valley, Kobeh Valley, and Smoky Valley, connected by the early route of the Lincoln Highway. Small-scale irrigation and natural water sources supported scattered homesteads like the Siri Ranch and Roberts Creek Ranch, while local education was served by the Grass Valley Sch and Simpson Park Sch.
