About this map

The confluence of heavy industrial infrastructure and extensive green space characterizes this 1990s landscape at the intersection of Cook, DuPage, and Will Counties. The massive Argonne National Laboratory Reservation dominates the western bluffs, while the central corridor is defined by the engineered waterways of the Chicago Sanitary and Ship Canal and the Calumet Sag Channel. These man-made arteries, flanked by the Atchison Topeka and Santa Fe Railway, illustrate the area's legacy as a vital Midwestern transportation and utility hub.

South of the industrial works near Sag Bridge, the terrain shifts toward the densely wooded wetlands of the Palos County Forest Preserve. This area is dotted with numerous water bodies like Saganashkee Slough and Bull Frog Lake. Local history and genealogy interest is high throughout, evidenced by the presence of institutions like St Marys Seminary and Mount Vernon Memorial Park (Cemetery) alongside growing residential developments in Darien and Lemont.
