1951 Map of Cascade

About this map

Missouri River hydrology and early mid-century infrastructure dominate this 1951 survey of the Montana heartland. The town of Cascade sits along the river's bend, serving as a hub for the surrounding ranching and rail economy. This map was produced as part of the Department of the Interior program for the development of the Missouri River Basin, an era of significant federal focus on water management. This is evidenced by the numerous irrigation ditches and the Elizabeth Reservoir (Aban'd) north of Rocky Gap.
