The California Oregon Approximate Boundary Line anchors this 1950s survey of the high basin floor and volcanic uplands in Siskiyou County. The town of Dorris serves as a primary hub along the Southern Pacific railroad, which tracks north-south alongside the Mt Diablo Meridian. The landscape is a mix of agricultural flats and wetlands, featuring the southern reaches of the Lower Klamath National Wildlife Refuge and the receding waters of Lower Klamath Lake. Numerous family ranches and landmarks like the Porterfield Ranch and Parsons Ranch suggest the localized cattle and farming economy of the era. To the south, the settlement of Macdoel sits near the Lakeview Cem, while several outlying schools such as Oklahoma Sch and Red Rock Sch reveal the distributed rural community structure before modern consolidation. Elevated features like Mahogany Mountain and Sheep Mtn rise sharply from the valley floor, overlooking the expansive Red Rock Valley.
