2023 Map of Hanford

About this map

The Manhattan Project National Historical Park preserves a critical layer of wartime industrial history along the Columbia River. This landscape is defined by the heavy footprint of federal administration, marked by the US Department of Energy Res Rd and large conservation boundaries like the Hanford Reach National Monument. While much of the area is restricted, the map reveals the remnants of earlier settlement patterns at Hanford, Edna, and May Junction. The local geography is anchored by Gable Mtn and the winding Hanford Ditch, which traces the arid terrain south of the Saddle Mountain National Wildlife Refuge. The map serves as a detailed record of how land use transitioned from early 20th-century irrigation and farming to one of the most significant nuclear research and environmental buffer zones in the country.
