About this map

The Cheyenne River carves through the landscape of the Cheyenne River Indian Reservation in this mid-century survey. By the time of the 1987 photorevision, the waters of Lake Oahe have filled the river valley, reaching a normal pool elevation 1617. The map illustrates the boundary between Dewey Co and Stanley Co along the river's path, showcasing a region defined by extensive plateaus such as Marion Flats and Kid Rich Flats.

Family ranching history is preserved through labels for the Vanderveer Ranch, Young Ranch, and Schiesser Ranch. Local heritage is further anchored by the Walking Horse Cem located on the northern side of the reservoir. The drainage patterns of Foster Creek and Mississippi Creek cut through the high ground, providing a detailed look at the hydrology of central South Dakota during this era of major river engineering.
