1954 Map of Okanogan

About this map

Oroville and the agricultural lands of the northern valley anchor this mid-century survey of North Central Washington. The map details a landscape where the river-and-rail economy of the Great Northern railroad supports settlements like Tonasket and Okanogan. To the east, the rugged terrain of the Colville National Forest and the Kettle River Range is marked by active mining sites including the Mountain Lion Mine and Knob Hill Mine. The expansive Colville Indian Reservation dominates the southern half of the sheet, containing the waters of Omak Lake and the community of Nespelem. A significant transformation of the landscape is visible along the eastern edge, where the Columbia River swells into Franklin D. Roosevelt Lake, creating a new shoreline and altering the geography around Inchelium and Marcus.
