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. |
