1970 Map of Prairie Du Rocher

About this map

Prairie du Rocher and its surrounding river bottoms are defined by a complex network of man-made and natural features along the Mississippi River. The landscape is bisected by the Missouri Pacific and St Louis - San Francisco railroads, which facilitated local industry like the Mines and Quarry near Danley. The historic significance of the area is anchored by the Modoc Rock Shelter National Historic Site, located where the bluffs meet the floodplain. Drainage patterns are meticulously managed through an extensive Levee system and man-made channels like The Discharge, which navigate the space between the river's islands, including Turkey Island and Schmidts Island. Small river-linked settlements like Kellogg, Thomure, and Modoc are connected to the Missouri side via a Ferry near Little Rock Landing, illustrating the vital river-and-rail economy of the mid-20th century.
