The Illinois River valley defines the western edge of this landscape, where complex backwaters like Babb Slough, Sawyer Slough, and Goose Lake flank the main channel near Chillicothe. This 1940s-era revision of earlier surveys captures a transition from the river-bottom industry of the Chicago Rock Island and Pacific railroad to the upland agricultural plateaus of Metamora and Cazenovia.
