About this map

The Missouri River cuts a deep, winding path through this portion of Montana, dictating the development of industrial and military infrastructure in the years following World War II. Hydroelectric power is central to the local economy, anchored by the Morony Dam, Ryan Dam, and Rainbow Dam. Near the bend in the river, the Great Falls Army Air Force Base sits adjacent to the C M ST P & P Yards, highlighting the area's strategic transportation and defense significance.
