1967 Map of Hart Lake

About this map

The Hart Mountain National Antelope Refuge dominates the eastern half of this 1960s landscape, rising sharply above the Warner Valley Lakes. This transition from the aquatic basin to the steep slopes of Hart Mountain National Antelope Refuge is defined by dramatic erosional features like Arsenic Canyon and De Garmo Canyon. The hydrology of the region is centered on the expansive waters of Hart Lake, which maintains a normal pool elevation of 4473 feet, and the smaller Anderson Lake to the north. Evidence of human land management in this high desert environment is sparse but visible through the presence of a Jeep Trail, a remote Well, and a Pump. Industrial activity is limited to a small Gravel Pit and Sandpit located near a Spillway along the eastern shore, providing a glimpse into the localized infrastructure of the mid-20th century.
