About this map

The Missouri River and Mississippi River converge in a complex hydraulic landscape of islands and chutes north of St. Louis. This confluence defines the geography of the Columbia Bottom area, where large river islands like Cora Island and Ellis Island sit amidst an intricate network of waterways including the Cora Island Chute and Alton Slough. The built environment on the Missouri side is characterized by residential expansion in Spanish Lake CDP and established neighborhoods such as Bellefontaine Neighbors and Glasgow Village.

Cultural and historical markers are concentrated along the bluffs and older roadways, including Fort Bellefontaine and the Old Jamestown CDP. Small family and church burial grounds like Bailey Cem and the Immaculate Conception Cem are preserved among the suburban grid. Infrastructure is vital to this river-bound region, represented by the Chain of Rocks Bridge and the industrial Chain of Rocks Canal that bypasses the natural Chain of Rocks rapids to the south.
