The confluence of the Rock River and Green River anchors this mid-century survey, where the industrial and transport infrastructure of Henry County is on full display. The Illinois-Mississippi Canal (Abandoned) remains a prominent landmark, stretching across the northern landscape with its historical engineering revealed through Lock No 28, Lock No 27, and Lock No 26. The area is a nexus for rail transport, featuring both the Chicago Rock Island and Pacific and the Chicago Burlington and Quincy lines passing through settlements like Colona and Green Rock.
