About this map

Monks Mound and Rattlesnake Mound stand as prominent landmarks within the American Bottoms, a flood plain of the Mississippi River characterized by a complex network of waterways. This 2021 survey of the Illinois interior highlights a landscape where heavy industrial and transportation corridors intersect with significant historical and natural features. Water management is evident through the presence of the Cahokia Canal, Harding Ditch, and Old Cahokia Creek, which drain the lowlands surrounding Horseshoe Lake and Canteen Lake.

Urban expansion from Granite City, Collinsville, and East St. Louis has created a dense matrix of residential neighborhoods like Maryland Place and Rosemont. For those tracing local heritage, the map identifies specific sites such as Emmert Cem and the Saint Johns United Church of Christ-Old Gem. The rail infrastructure, including the Conrail Rd, underscores the region's long-standing role as a central Midwestern transit hub.
