The Mississippi River valley anchors this mid-century survey, cutting through the high bluffs of the Tri-State area where Iowa, Wisconsin, and Illinois meet. The industrial and transit landscape is defined by the heavy presence of the Illinois Central and Chicago and North Western railroads, which connected the river hubs of Dubuque and Cedar Rapids to the mineral-rich uplands. Mineral extraction remains a visible legacy on this sheet, particularly the Numerous lead and zinc mines scattered across the Wisconsin side near Platteville.
