1961 Map of Thacker Pass

About this map

Kings River Valley and the surrounding high desert terrain are defined by the critical water sources that supported livestock and early travel in this part of Humboldt County. The southern portion of the map is dominated by the Quinn River and Quinn River Lakes, adjacent to the northern boundary of the Fort Mc Dermitt Indian Reservation. These permanent water features stand in contrast to the seasonal drainages of the Montana Mountains and the Double H Mountains, where named springs such as Sheep Ranch Springs and Rock Spring provided vital landmarks for ranchers and explorers. Navigation through the complex topography is facilitated by natural gaps like Thacker Pass and Sand Pass, connected by a network of unimproved roads and jeep trails that reflect the area's isolation during the early 1960s.
