About this map

Prairie du Rocher sits at the base of the Mississippi River bluffs, where the Missouri Pacific railroad traces the line between the fertile bottomlands and the upland hollows. The landscape is defined by the sharp transition from the river plain, protected by an extensive levee system, to the deeply eroded bluffs containing Barbeau Hollow and Burns Hollow. Cultural history is prominently represented by the Modoc Rock Shelter National Historic Site, documenting millennia of human presence in these limestone overhangs.

Industrial and river-based activity is evident throughout the corridor, from the Quarry Simms Pit to the transport hubs of Kellogg and Mudds Landing. Along the Mississippi River, large islands like Schmidts Island and Turkey Island shift with the current, while small settlements like Modoc and Marigold anchor the interior. The map also captures the ferry crossing at Little Rock Landing, a vital link to the Missouri side of the river.
