About this map

The Humboldt River corridor dominates this 1930s landscape, serving as the vital artery for both the Southern Pacific and Western Pacific railroads. Between the Sonoma Range and the Shoshone Range, the map reveals a network of high-desert ranching and mining operations typical of the Great Basin era. Notable landmarks such as the Site of Old Indian Fort and the Auld Lang Syne mine indicate the region's layered history of conflict and industry.

Remote outposts like Adelaide and Goldbanks are connected by the Victory Highway, while smaller operations like the Pearce Sch and the Siard Ranch highlight the sparse but established rural infrastructure of Pershing County and Humboldt County. From the geothermal activity at Kyle Hot Springs to the copper mining at Copper Basin, the survey documents a region defined by its geological resources and the infrastructure built to extract them.
