The Mighty Mississippi from the air. The top picture is just after liftoff, looking south. The pinkish strip down the center is the cobblestone levee, dating from the 19th Century. The river is very low. When the water is up, like in this picture from last May, the street uphill to the right can be completely covered. The highest I've seen it is about two-thirds up the floodwall to the right of the street. That's a lot of water.
The bottom picture is looking north, upriver. The graceful Eads Bridge crosses the river, followed by the prosaic McKinley Bridge. Note all the barges pulled over to the riverbanks behind the bridges. The Mississippi south of St. Louis has such a gentle descent that there are no locks and dams. The first is a few miles to the north of us. It was closed for dredging at the time, stopping all the river traffic.
