1968 Map of Cannon Ball SE

About this map

Lake Oahe dominates the central landscape of this late-1960s survey, marking the broad expanse of the Missouri River as it flows between Emmons and Sioux counties. The map captures the transition of the river into a massive reservoir, with the Standing Rock Indian Reservation Boundary running through the center of the waterway. On the eastern shore, the Beaver Creek Public Use Area and the Sunburst Lake National Wildlife Refuge indicate a shift toward conservation and recreation in the Missouri River Basin.
