About this map

The Missouri River winds through the heart of this landscape, its course punctuated by significant industrial and civic infrastructure on the outskirts of Great Falls. This post-war survey illustrates a region where hydroelectric development, such as Rainbow Dam and Morony Dam, Coexists with long-established agricultural interests and rural education. The presence of the Great Falls Army Air Force Base in the southwest corner signals the era's growing military footprint, while institutional sites like the State Deaf & Dumb School and State Fish Hatchery reflect the area's specialized social and environmental management.
