    Mississippi River

    Our tour begins by saying goodbye to the Gateway Arch and hello to the Mighty Mississippi River, the longest southerly flowing river in the entire world! As we cross the River, which averages about 15 feet deep around here, some of the water below has spent months getting here, traveling thousands of miles from as far away as Minnesota, Canada, and Idaho. The water below us will flow another 1300 miles during the next two to three weeks before reaching its final destination, the Gulf of Mexico.

Preview mode limited to first 3 locations.
