1973 Map of Big Bend Dam 4 SW

About this map

Old Indian Treaty Boundary lines cross this Buffalo County landscape, marking the historical intersection of tribal lands and federal survey divisions. The terrain is defined by the winding paths of Elm Creek and Crow Creek, which drain the open prairie of the Crow Creek Indian Reservation Boundary. This 1973 survey focuses on a quiet stretch of South Dakota rangeland where fence and field lines are noted as distinct topographic markers. The absence of concentrated settlements emphasizes the vast, agricultural nature of the reservation land during the mid-1970s, providing a clear record of the physical boundaries and water sources that dictated land use in the Big Bend region.
