1948 Map of Portage

USGS Topo · Published 1962

About this map

The Missouri River cuts a deep, winding course through the plains of Central Montana, defining the landscape where the industrial and military presence of the Great Falls area meets the surrounding ranchlands. The southern edge of the map is anchored by significant infrastructure, including the Morony Dam and Rainbow Dam, alongside the Great Falls Army Air Force Base. These sites, along with the C M St P & P Yards and the State Deaf & Dumb School, reflect a period of substantial mid-century development.
