The Mississippi River and the meandering Cuivre River dominate this 1950s landscape, defining the border between Illinois and Missouri. The confluence area is a complex network of backwaters and sloughs, including Argent Slough and Cuivre Slough, which frame large river islands like Cuivre Island and Peruque Island. Settlement is concentrated along the Chicago Burlington and Quincy railroad line, where the communities of Winfield, Brevator, and Old Monroe are established on the higher ground west of the floodplains.
