The River (1937 movie)

The River is a 1937 short documentary film which shows the importance of the Mississippi River to the United States, and how farming and timber practices had caused topsoil to be swept down the river and into the Gulf of Mexico.

It was written and directed by Pare Lorentz and, like Lorentz's earlier documentary The Plow That Broke the Plains, has been deemed "culturally significant" by the United States Library of Congress and selected for preservation in the National Film Registry.
