Mississippi River/Delta Field TripSept. 28-Oct. 3, 2004: R. Douglas Elmore

A couple of quotes from a wise man.

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise...”- Mark Twain in Eruption

“One who knows the Mississippi River, will of her not allow himself, that 10,000 river commissions with the minds of the world at their back cannot curve it or confine it, cannot say to it go there and make it obey, cannot save a shore which has been sentenced, cannot bar its path with an obstruction which is will not tear down, dance over, or laugh at.” Mark Twain

First Day-The long road to Louisiana

The second day-Old River Control
