About this map

The Okanogan River and Similkameen River meet south of Oroville, forming a valley landscape defined by the Great Northern Railroad and intricate water management. Irrigation and topography are central here, with flumes and siphons supporting agricultural patches like Whitestone Flats. The international border with Canada is marked at Boundary Point on the northern shore of Osoyoos Lake, where the railroad enters the United States.

Industry and local infrastructure appear in the form of the Lucky Knock Mine and numerous gravel pits, while the town of Oroville shows early urban development including a Sewage Disposal plant and Gaging Sta. To the east, the Okanogan National Forest covers high ground like Mt Hull, sheltering numerous springs and remote peaks. This mid-century survey captures the region as it balanced natural resource extraction with the growing agricultural footprint of Ellisford and Cordell.
