About this map

The Des Plaines River corridor serves as the industrial and transit backbone of this 1920s landscape, where three major waterways—the Chicago Sanitary and Ship Canal, the Illinois and Michigan Canal, and the river itself—parallel the Atchison Topeka and Santa Fe Railway. This dense corridor of infrastructure cuts through the rolling topography of Lemont and Downers Grove, illustrating the heavy engineering required to link the Great Lakes with the Mississippi watershed.

Genealogists will find a wealth of local landmarks, including the Visitation Boys Camp, the Lower Cass Cemetery, and numerous rural schoolhouses such as the Derby School and Gower School. The map captures several small post office settlements and stations like Tiedtville P.O. Santa Fe Park Sta. and Willow Springs P.O. and Sta., documenting the localized community centers that existed before modern suburban expansion transformed the southwestern Chicago periphery.
