About this map

Osoyoos Lake straddles the international boundary in this early twentieth-century survey of Okanogan County, where the high-altitude landscape of northern Washington meets the United States Canada Boundary Line. This era is defined by active mineral extraction, evidenced by the Okanogan Free Gold Mine near Oroville and the Poland China Mine located northeast of Molson. The map reveals a network of emerging mountain settlements and valleys, including the Aeneas Valley and Chewiliken Valley, before extensive modern development reached these higher elevations.

Large portions of the eastern and southern sections are designated as the Colville National Forest, encompassing significant peaks such as Mt. Bonaparte and Mt. Annie. For genealogists and local historians, the sheet identifies isolated community centers like Chesaw, Bolster, and Havillah, as well as family-named landmarks like the Crisp Ranch. The survey captures the complex drainage systems of Bonaparte Creek and the West Fork Sanpoil R. as they carve through the highlands of the Okanogan.
