The Mississippi River is polluted! It’s for barges only. Dams on the upper river were built for flood control. These are a few of the myths about the Mississippi that persist.

For the Mississippi Minute, I offer a few quick thoughts about Moro Island, a place near Sainte Genevieve, Missouri, that I know as a great place to camp but that once was home to a small community.
