Why Is the Mississippi the MOST DANGEROUS RIVER in the World?
3,730 kilometers. 41% of the territory of the continental United States. The waters of 31 states.
This is the Mississippi. America's main river. And it holds secrets that the textbooks don't mention.
In this video — 10 secrets of the Mississippi: Cahokia, the largest city in North America, which vanished without a trace or a memory; the Old River Control Structure, an installation that keeps the river on a leash every single day; New Orleans, sinking 2 centimeters a year below sea level; 500 sunken steamboats lying beneath the fields of Louisiana; a delta losing a football field every 40 minutes; Nauvoo, a ghost town that could have become Chicago; tunnels beneath Memphis, found by chance and immediately sealed; the 1811 earthquake that made the river flow backward; a moving border between states that the river is shifting right now; and Saint Anthony Falls, which retreated while Minneapolis grew up around it.
