1950 Map of Imlay SW

About this map

The White River carves a deep, winding path through this portion of the Pine Ridge Indian Reservation, where the landscape is defined by the sharp transition between tablelands and the braided river bottom. This 1950s era documentation, with later revisions in the 1970s, captures a rural landscape where drainage patterns like Big Hollow Creek and Wind Creek converge toward the main river valley. A significant genealogical marker is found at the St Mary Magdalene Cem located in the southwestern corner near the mouth of Porcupine Creek. The map illustrates the complex badlands topography typical of this region, with numerous ephemeral streams such as Cottonwood Creek and Spring Creek dissecting the high plains. The lack of formal town sites emphasizes the remote, pastoral character of the reservation during the mid-20th century.
