The Rock River valley serves as the central artery for this mid-century portrait of northern Illinois and southern Wisconsin, connecting the industrial hubs of Rockford, Beloit, and Janesville. This 1955 edition reflects a landscape defined by its transition from the glacial topography of the Kettle Moraine and Lake Koshkonong to the fertile agricultural prairies and growing suburban reaches of Elgin and Arlington Heights.
