About this map

Summer Lake and Lake Abert dominate this high-desert landscape in south-central Oregon, illustrating a complex hydrological system of endorheic basins. The Chewaucan River flows through the extensive wetlands of the Upper Chewaucan Marsh and Lower Chewaucan Marsh before reaching the hypersaline waters of Lake Abert. The dramatic verticality of the region is defined by massive fault scarps, most notably the Abert Rim and Winter Ridge, which rise sharply above the basin floor.

Agricultural life in the mid-1970s is evidenced by several established properties, including O'Keefe Ranch and Kittredge Ranch, situated near the settlement of Paisley. While the western portion of the map is heavily forested within the Fremont National Forest, the eastern landscape shifts toward the arid expanse of Coleman Flat and the Alkali Valley. This survey captures the intersection of traditional ranching and significant natural features like the Gearhart Mountain Wilderness and the Summer Lake State Game Management Area.
