Malmstrom Air Force Base dominates the southeastern quadrant of this mid-1960s study, showcasing the massive scale of military aviation infrastructure adjacent to the Missouri River. The river itself is the centerpiece of the local industrial and natural landscape, marked by a succession of hydroelectric sites including Ryan Dam, Rainbow Dam, and Cochrane Dam, which harnessed the descent of the water at Rainbow Falls and Crooked Falls.
