The Cortez Mountains and Dry Hills dominate this high-desert landscape along the border of Lander and Eureka counties. The terrain is defined by dramatic elevation changes, where several deep drainages like Fye Canyon and Hog Canyon cut through the ranges. This 2018 survey reveals a network of primitive roads and trails that serve as the primary conduits through the basin and range geography, including the Cortez Beowawe Rd and J D Ranch Rd. These routes connect remote water sources such as Dugout Spring and Rossi Spring, which remain critical landmarks in an arid environment where Horse Cr. and Pine Cr provide limited seasonal flow. The map illustrates how human activity is concentrated around these water points and through the traversable Garden Gate Pass, bridging the gap between Grass Valley and Pine Valley.
