1969 Map of Artichoke Butte NW

About this map

The Lake Oahe Missouri River dominates this stretch of the northern Great Plains, representing a landscape transformed by the mid-century development of the Missouri River Basin. The reservoir's vast waters have inundated the former river valley, though the map still identifies the historical locations of Forest City and South Forest City along its eastern banks. This 1969 survey captures the intersection of Dewey, Potter, and Sully counties, where the western shore is defined by the Cheyenne River Indian Reservation Boundary. Several local drainages, including Pascal Creek, Parker Creek, and Alberts Creek, feed into the reservoir, carving deep draws into the high prairie terrain. The presence of a small Gravel Pit near the river's edge suggests the localized extraction of materials used for road building and infrastructure during this period of regional water management.
