1979 Map of Simpson Park Mts

About this map

Simpson Park Mountains and the Roberts Mountains dominate this central Nevada landscape, separated by the expansive Grass Valley. This late 1970s survey captures a transition in land use, where traditional ranching and mining pursuits exist alongside modern infrastructure. The Lone Mountain Mine sits at the southern edge of its namesake peak, while the Eureka Airport and various landing fields indicate the region's reliance on aviation for connectivity across the high desert. Numerous water sources, such as Rye Patch Spring, Valley Spring, and Underwood Spring, are carefully mapped, highlighting their critical importance in this arid environment. The boundary between Lander and Eureka counties bisects the terrain, which ranges from the depths of Ackerman Canyon to the heights of Mount Callaghan within the Toiyabe National Forest.
