About this map

The Colville Indian Reservation Boundary defines much of this landscape in Okanogan and Douglas Counties, where the Columbia River carves a deep path through the plateau. This mid-century survey documents a transition in rural education and community centers, specifically noting the Del Rio School and Ragged Butte School as defunct, while the Del Rio Grange Hall remains a local landmark.

The river is a focal point of the geography, characterized by hazardous water features such as Granite Rapids, White Cap Rapids, and the sharp turn at Gaviota Bend. Uplands like Stubblefield Point and Boot Mountain look down upon scattered agricultural flats and small settlements such as Timentwa and Nilles Corner. The presence of several small lakes, including Figure Eight Lake and Long Lake, provides contrast to the dry basins of Achimin Basin and Tumwater Basin.
