Malheur Lake and the vast marshlands of the Malheur National Wildlife Refuge dominate this late-1950s landscape in Harney County. The drainage patterns of the high desert are intricately detailed, showing the West Fork Silvies River and East Fork Silvies River as they feed into the lake's basin. This era shows the developed infrastructure of the refuge, including the National Wildlife Refuge Headquarters, Sod House Dam, and the Sod House School near the Donner und Blitzen River.
