About this map

The industrial and institutional landscape of southwestern Cook County is defined here by the confluence of the Des Plaines River and two major man-made waterways. The Chicago Sanitary and Ship Canal and the older Illinois and Michigan Canal run parallel through the valley, creating a corridor of transport that historically fueled the growth of Lemont and Sag Bridge. To the north, the sprawling Argonne National Laboratory Reservation occupies a massive footprint, reflecting the Cold War era's scientific expansion into the suburbs.

Local life is anchored by family-named schools and religious sites like the Forinier Institute and St James Ch, while the southern reaches show a mix of recreation and agriculture. Notable sites including the City of Chicago Correction Farm and Hinsdale Airport illustrate the diverse land use of the period, from municipal services to early aviation. Large recreational and conservation areas such as the Palos Forest Preserve and Saganashkee Slough dominate the eastern topography.
