2020 Map of Hanford

About this map

The Manhattan Project National Historical Park preserves a critical era of American nuclear history on this landscape along the Columbia River. This modern survey documents the sensitive geography of the region, where the Hanford Reach National Monument and Saddle Mountain National Wildlife Refuge border the historic Hanford townsite. The terrain is marked by infrastructure related to federal operations, including the US Department of Energy Res Rd and the Hanford Ditch, reflecting the long-term industrial and environmental footprint of the site. While modern conservation and recreation are represented by the Wahluke Walking Trail, the map also preserves the locations of early local place names like May Junction and Edna, providing a spatial record of the area's transition from early 20th-century agriculture and irrigation to one of the most significant government projects in history.
