About this map

Fountain Bluff stands as a prominent landmark above the Mississippi River floodplains in this late-1940s survey of southern Illinois. The landscape is defined by the sharp contrast between the flat river bottoms and the heavily dissected hills of the Shawnee National Forest. Along the river, historical transportation routes are well-preserved, including the site of Rattlesnake Ferry and Kings Ferry. The rail network is equally vital, with the Illinois Central Railroad and Missouri Pacific Railroad navigating the narrow corridor between the bluffs and the Big Muddy River.
