Lake Michigan dominates the northern horizon of this mid-century portrait, where the dense urban grid of Chicago transitions into the industrial heartlands of northwest Indiana and the agricultural plains of Michigan. This 1983 revision shows the mature development of the interstate system, with the Chicago Skyway and Borman Expressway cutting through the complex corridor between Gary and Hammond. The map highlights a significant tension between heavy industry and conservation, represented by the presence of Indiana Dunes National Lakeshore alongside the steel-producing centers of East Chicago. Moving inland, the Valparaiso Moraine provides a geological backbone to the landscape, while the southern reaches reveal specialized conservation areas like the Beaver Lake Prairie Chicken Refuge and the Jasper-Pulaski State Game Preserve, illustrating the region's efforts to preserve native prairie and wetland habitats amidst expanding settlements.
