The Grafton riverfront and the intricate confluence of the Illinois River and Mississippi River dominate this mid-century survey. The landscape is sharply divided between the bluff-lined northern shore in Jersey County, where deep ravines like Camden Hollow and Distillery Hollow cut through Pere Marquette State Park, and the expansive floodplain of Portage Des Sioux to the south. This lowland area is a complex network of chutes and islands, including Mason Island and Enterprise Island, punctuated by numerous backwater lakes such as Mertz Lake and Marais Temps Clair.
