St. Louis On The Air

Spanning more than 2,300 miles, the Mississippi is one of the longest rivers in the world. The waterway has the distinction of being both a significant ecosystem and a commercial navigation route, which often leads to tension and competing visions for its future. In his new book “The Great River: The Making & Unmaking of the Mississippi” journalist Boyce Upholt traces the history of the river and presents deep questions about the consequences of infrastructure and where the boundaries of nature lie.
