The confluence of the Illinois River and its tributaries forms the geographic heart of this late-nineteenth-century survey. At the center of this network lies Ottawa, a significant transit hub defined by the Illinois and Michigan Canal and major rail corridors. The presence of the Chicago Rock Island and Pacific Railway and the Chicago Burlington and Quincy Railway running parallel to the waterways illustrates the era's transition from waterborne freight to high-speed rail dominance.
