About this map

Swan Lake Rim defines the dramatic topography of this Klamath County landscape, dropping sharply from high plateaus into the flat expanse of Swan Lake Valley. In the mid-1980s, this area remained largely defined by livestock ranching and timber transit, evidenced by family holdings like Bodnar Ranch and Drews Ranch. The central basin contains the seasonal waters of Swan Lake, with significant portions of the valley floor marked as an area subject to inundation, ringed by engineered spoil banks.

Transportation through this high-desert environment is dominated by the Oregon California and Eastern Railroad, which skirts the eastern edge through the Yonna Valley. The map records numerous vital water sources essential for remote operations, including Applegate Spring, Fourmile Spring, and Jack Frost Spring. Higher elevations like Hopper Hill and Squaw Flat overlook a network of unimproved roads and a major Gas Pipeline that traverses the rugged terrain between the lake bed and the eastern valley floor.
