About this map

The Colville Indian Reservation dominates this 1950s landscape, where the rugged topography of the Okanogan and Douglas county line meets the powerful flow of the Columbia River. This survey captures a moment when rural life centered around small hubs like Nilles Corner and the local Grange Hall. The distribution of education across the plateau is clearly visible, from Long Lake Sch to the specifically noted Del Rio School (Aban'd) and Ragged Butte School (Aban'd).

Navigation along the river is marked by significant obstacles and landmarks, including Box Canyon, Eagle Rapids, and Parson Rapids. The upland areas, characterized by Timentwa Flats and Goose Flats, are dotted with numerous small lakes such as Figure Eight Lake and Omak Lake. This detailed mapping reveals the complex network of plateaus and basins, like the Achimin Basin, that defined the region's cattle and grain geography mid-century.
