The crescent shape of the Ohio River between Metropolis and Cairo was one of the busiest "interstate highways" as settlers on flatboats headed west. Mound City and Cairo were staging areas, hospitals and a cemetery for the Civil War. In 1800, half the US military was housed at Grand Chain, with its commander considering whether to start his own country in the southwest. Earlier, the King of France had sanctioned a huge buffalo hide tanning operation at the same place.
Since the beginning of time, this area has seen dinosaurs and tropical conditions, as well as the glaciers. Global warming? The Illinois State Museum says glaciers have come and gone across much of the state, several times.
Cairo is at the confluence of the Ohio (below, right) and Mississippi rivers. The confluence of 200 years ago was at the southern tip of the business district, the north side of the cultivated fields, more than a mile north of where it is now.
