The Mammoth Tree that Once Ruled the East

Picture a tree that was wider than a midsize car and as tall as a
ten-story building.  Now picture a 3.5 billion of them
stretching across the Appalachian region.  The American
Chestnut once dominated this landscape but completely disappeared
in less than a couple of decades.  Join us as we explore
what happened to this tree and how it's making a comeback.
