Riverfest 2010

Clark Switzer gives a history lesson at the site of the  Knox Mine disaster.  On January 22nd, 1959, a thin rock roof of a mine running under the Susquehanna River collapsed and  water and ice poured into the mine creating a vortex approximately 150 feet in diameter.   A stunning photograph and more information can be found at undergroundminers.com.  Twelve workers died, but sixty-nine managed to escape the billions of gallons of water that poured down into the mines.
