Cassville, Grant County. August, 1970. Altitude c. 3,000 feet. This is an expansive, high oblique view of the Mississippi River valley to the northwestern horizon. The community of Cassville is at center, its two coal-fired electrical generating plants prominently spewing white plumes of smoke westward over the river. In the foreground, on a low terrace near the river, is the runway of the Cassville Municipal Airport. Adjacent to the runway near the base of the wooded bluff are the tracks of the Burlington Northern Railway and County Highway VV. Iowa lies across the valley at upper left, and the city of Guttenberg is just visible within the valley at upper right.
