1954 Map of Grafton

About this map

The confluence of the Illinois River and Mississippi River creates a complex landscape of islands and chutes at Calhoun Point. In the mid-20th century, the town of Grafton served as a focal point along the northern bluffs, overlooking a network of river features including Mason Island, Island 526, and Perry Island. To the south, the flatlands of Portage Des Sioux are marked by agricultural drainage and natural sloughs like Marais Temps Clair. Transport and recreation are evident through the Burlington Northern railroad lines and the sprawling Pere Marquette State Park, which includes a Historic Monument. The map also captures local educational and aviation history at Phelps Sch, Lake View Sch, and Smartt Airfield, providing a detailed look at this river junction's infrastructure before significant modern expansion.
