About this map

The Sisseton Indian Reservation dominates the landscape of this mid-century survey, stretching across the lake-strewn glacial terrain of the Coteau des Prairies. This region at the borders of South Dakota, North Dakota, and Minnesota is defined by a complex hydraulic system, where the continental divide separates waters flowing toward the Hudson Bay via the Bois de Sioux River from those heading toward the Gulf of Mexico through the Minnesota River. Large glacial lakes like Lake Traverse and Big Stone Lake form the natural boundary between states, while inland, smaller bodies such as Enemy Swim Lake and Waubay Lake are protected within the Waubay National Wildlife Refuge.
