The Sangamon River meanders prominently through the center of this landscape, its floodplains defined by a complex network of tributaries such as Lattimore Creek, Concord Creek, and Indian Creek. The town of Petersburg serves as the primary hub, situated near the confluence of several early transportation routes including the Gulf Mobile and Ohio and the Chicago and Illinois Midland railroads.
