About this map

Columbia River waters dominate this mid-1980s landscape at the intersection of Grant, Benton, and Franklin counties. The river flows past Locke Island and beneath the prominent White Bluffs, a region increasingly dedicated to conservation and government oversight. Large tracts of land are designated as the Saddle Mountain National Wildlife Refuge and the Habitat Management Site (DOE), reflecting the complex environmental and technical management of the Hanford area.

Traces of earlier human enterprise remain visible through the Old RR Grade and the small settlement of Ruth to the south. The infrastructure of the era is marked by a Filter Plant, Substation, and Retention Basin, while the Wahluke Slope and Saddle Mountain define the high terrain. This map captures the transition from historic rail transport to modern resource and habitat management in the high desert of the Pacific Northwest.
