USGS Topo · Published 1959About this map
The Missouri River forms the central spine of this mid-century landscape, serving as the border between Nebraska, South Dakota, and Iowa. This period is marked by massive infrastructure changes, most notably the Gavins Point Dam under construction, which began to reshape the river valley into Lewis and Clark Lake. The map details a complex network of transportation and institutional geography, featuring the Norfolk State Hospital and regional hubs like Yankton and Sioux City.
