About this map

The Mississippi River floodplain dominates this 1970 landscape, where the Illinois and Missouri border follows the winding river channel near Jackson Island and Schmidts Island. Beneath the steep bluffs of the American Bottoms lies the Modoc Rock Shelter National Historic Site, a significant archaeological landmark. The settlement of Prairie du Rocher sits at the base of these bluffs, serving as a hub for the surrounding agricultural bottomlands and nearby quarries.

Transportation networks define the region's industry, with the Missouri Pacific and St Louis - San Francisco railroads paralleling the river. River access is noted at Mudds Landing and Little Rock Landing, while unique geological features like Fish Cave and Fallert Cave punctuate the limestone bluffs. Small settlements such as Modoc and Kellogg provide a look at the rural character of Randolph County during this era.
