About this map

The Kings River Valley and surrounding desert ranges define this early 1960s landscape, a region marked by extensive cattle ranching infrastructure and remote mountain passes. In the south, the Quinn River meanders toward the Quinn River Lakes, passing just below the northern edge of the Fort Mc Dermitt Indian Reservation. The geography is dominated by the massive Double H Mountains and the Montana Mts, separated by the namesake Thacker Pass.

Surface water is a critical feature across this arid terrain, with numerous named sources such as Sheep Ranch Springs, Rock Spring, and Garden Spring providing life to the high desert. Local travel during this era relied on a network of unimproved routes and livestock paths, including the Old Hog John Road, Ninemile Road, and various unnamed Jeep Trails. Traces of local industry appear in the form of a Gravel Pit and a lone Substation, highlighting the limited but vital human footprint in this part of Humboldt County.
