The Missouri River corridor undergoes a massive transformation on this 1950s survey, dominated by the newly completed Garrison Dam and the rising waters of the Garrison Reservoir. This engineering feat reshaped the landscape of the Fort Berthold Indian Reservation and led to the creation of Riverdale and Pick City to support the dam's power plant and infrastructure. Beyond the river, the landscape is defined by the high density of prairie potholes, labeled here as Numerous Lakes, which dot the terrain between the Prophets Mountains and Hog Back Ridge.
