The Missouri River and Mississippi River reach their confluence just beyond the boundaries of this survey, defining a landscape of low-lying islands and complex hydrology. The massive Columbia Bottom conservation area and Chouteau Island dominate the riverine geography, while the Chain of Rocks Bridge provides a vital link across the water near St. Louis. This area is characterized by its dual identity as both a major industrial and transit corridor—evidenced by the Chain of Rocks Canal and proximity to Granite City—and a region preserved for its natural floodplains.
