1966 Map of Mott SW

About this map

The Cannonball River meanders through the northern reaches of this landscape, carving a valley across the plains of southwestern North Dakota. This 1966 survey, part of the Department of the Interior's Missouri River Basin development program, provides a detailed look at the drainage patterns of the Missouri Slope. Tributaries such as Chilton Creek and Dayton Creek feed into the river system, while the large Van Patton Slough dominates the central lowlands, illustrating the region's semi-arid hydrology. The terrain is marked by distinctive formations like Forsch Rocks and organized into the historical townships of Farina, Chilton, Castle Rock, and Ashby. This map documents a transitional period in the region's management, just before modern water control projects fully reshaped the plains.
