2017 Map of Hanford

About this map

The Manhattan Project National Historical Park preserves a critical site of twentieth-century American science and defense history along the banks of the Columbia River. This landscape is dominated by the remnants of the decommissioned Hanford Engineer Works, which forever altered the small farming settlements that once occupied this bend in the river. Significant geological and infrastructure features include the prominent rise of Gable Mtn and the winding Hanford Ditch, which once supported regional irrigation. The map reveals the layout of roads like Army Loop Rd and Hanford Rd that serve this restricted government site, while also showing the quiet transition into the Saddle Mountain National Wildlife Refuge to the north. Smaller locales such as Edna and May Junction suggest the earlier agricultural network that predated the site's mid-century transformation.
