The confluence of the Mississippi River and the Illinois River dominates this landscape, where the high bluffs of Jersey County meet the sprawling bottomlands of Missouri. The riverfront at Grafton serves as a gateway to the steep, wooded ravines of Pere Marquette State Park, a terrain marked by deep hollows such as Graham Hollow and Jerseyville Hollow. This 1990s revision shows the complex hydraulic network of the river system, featuring numerous chutes and islands including Mason Island and Enterprise Island, alongside the managed waters of Marais Temps Clair. To the south, the flat floodplain of St. Charles County supports aviation at St Charles Smartt Airfield and the small agricultural community of Orchard Farm. Local history is preserved in sites like Scenic Hill Cem and Barweis Cem, while the recreational character of the river is seen at Chautauqua and along the Mc Adams Highway.
