Stone Walls (HOLIDAY REBROADCAST)

It's been said that "to know New England well, one must know its stone walls". At one time there were more than 240,000 miles of stone walls in New England, used to divide property, hold in farm animals and support plant life. Today, our guest says, there's a lot we can learn from these stone structures, including the natural, cultural and human history of New England life. Mike's guest is Robert Thorson, professor of geology and geophysics at the University of Connecticut and author of Stone by Stone: The Magnificent History in New England's Stone Walls.
