The Mississippi River dominates this mid-1930s survey, defining the border between Illinois and Iowa with an intricate network of chutes, sloughs, and islands. This environment shaped a cluster of riverside settlements and transit points, including Gulfport and Orchard City, positioned where the Chicago Burlington and Quincy railroad crosses the floodplains. The map reveals the hydraulic complexity of the era, showing how the Diversion Channel and Old Channel redirected the flow near Whitehead Island.
