USGS Topo · Published 1966About this map
The Missouri River forms at the confluence of the Madison River and Gallatin River, a landscape-defining intersection mapped here just after the war. This survey highlights an intricate network of early irrigation infrastructure, featuring the Lowline Canal, Moreland Canal, and Lewis and Clark Canal that turned the valley into a productive agricultural hub. Settlement patterns are closely tied to the water and the competing rail lines of the Chicago Milwaukee St Paul and Pacific and the Northern Pacific.
