About this map

Industrial hubs and transit corridors define this 1930s landscape across the American Bottoms of St. Clair County. The Mississippi River forms a dominant western border, shaping the rail-heavy developments at Monsanto and the massive rail yards of the Missouri Pacific Railroad near Dupo. This era shows a complex network of steel and electricity, including the St Louis and Waterloo Electric Railroad and the St Louis Belleville and Electric Railroad, reflecting the dense commercial connectivity between Illinois and St. Louis.

Away from the riverfront, the map transitions into the bluffs of Sugar Loaf, where a more rural character persists through landmarks like St Josephs Cem and several local schoolhouses including Droit Sch and Jackson Sch. Notable water features such as Goose Lake, Lily Lake, and the winding Cahokia Slough illustrate the natural drainage of the lowlands before modern flood control extensively altered the basin. Small settlements like Prairie du Pont and Falling Spring provide focal points for genealogical research into the area's early 20th-century community structure.
