1965 Map of Seymour Reservoir

USGS Topo · Published 1969

About this map

Rudolph Valley defines the northern reaches of this mid-1960s landscape, where the drainage patterns of the Missouri River Basin shape the local geography. The area is marked by a network of intermittent waterways and coulees, including the North Fork White Rock Coulee and Big Warm Creek. Human modification of the arid terrain is evident in the presence of water management features such as Seymour Reservoir and Bass Reservoir, which served as critical infrastructure for ranching and settlement in Phillips County. The small settlement of Rankin stands as a primary point of interest for local historians, situated amidst a complex topography of ridges and drainages like Wild Horse Creek. This survey provides a precise record of the land use and water resources in this portion of Montana during the mid-twentieth century.
