1966 Map of Sage Hen Hills

About this map

The Charles Sheldon Antelope Range defines this high-desert landscape, where the borders of Nevada and Oregon meet amidst a series of prominent volcanic plateaus and ridges. This mid-1960s survey documents a territory focused on wildlife conservation and livestock management, dominated by the Sage Hen Hills and the broad expanse of Horse Heaven. The topography is characterized by flat-topped mesas like Springs Table and isolated peaks such as Catnip Mountain, illustrating the geological transition between the Great Basin and the Columbia Plateau. Vital water sources are scarce across this arid terrain, with Rock Spring and various unnamed springs serving as critical landmarks for both range animals and the few travelers navigating the network of primitive Jeep Trails that crisscross the sagebrush flats.
