The Mississippi River is an American icon. It's a body of water that's been shaped as much by cultural processes as by environmental ones. From the state lines it draws to its role in literature and the arts, it's a river that flows deep in the American psyche.
This episode is about the boundaries and horizons of the Mississippi — its deep geologic past, its history as a route to freedom, and its meaning today. [Broadcast Date: August 3, 2016]
