This is the map from the Mississippi River North book shows the locations of the images. I used to think the Mississippi flowed in a relatively straight line from northern Minnesota to the Gulf, but this map shows how it makes a fish hook in the north flowing east before it starts its journey south. I’ll post some more pages. .If you would like to order the book :
