1967 Map of Jacobs Reservoir

About this map

Hart Mountain National Antelope Refuge dominates this high-desert landscape in Lake County, defining a region where water management and wildlife conservation intersect. The terrain is characterized by a series of shallow lakes and depressions, including Mound Lake, Long Lake, and Jack Lake, which dot the arid plateau. Central to the area's hydrology is Jacobs Reservoir, fed by Guano Creek. A network of Jeep Trails provides the primary means of traversal through features like Clover Swale and Riffle Canyon. The map records a specific moment in the mid-1960s when the region's scattered water bodies, such as School Section Lake and Robinson Lake, served as vital landmarks for navigation and land use within the refuge's boundaries.
