What's geomorphology and why does it matter? (Asking for a friend)

Ten years ago, University of Washington professor David Montgomery published his influential book “Dirt: The Erosion of Civilizations.” One year later, he received a MacArthur Genius fellowship, and continued his research in geomorphology: “the branch of geology that is concerned with the structure, origin, and development of the topographical features of the earth's surface.”

David Montgomery spoke at Town Hall Seattle on May 9. Sonya Harris recorded his talk.
