I always knew that rivers changed their courses periodically.  Not always for the same reason and usually with much rhyme when closely investigated.

The mighty Mississippi is one such river that we have known about all our lives.  It has existed ever since the center of the continent rose from the bottom of the sea.  Every thousand years or so some part of the river shifts course.

Mr. Harold N. Fisk has charted many of the changes in the Mississippi, especially the lower river valley.  Seeing it graphically illustrated is truely amazing.

Have a look.  This is one cool map.

Actually the entire blog is amazing.  Whenever I need a change of pace or am just plain bored I check out a little more of this blog.
