~ Mysterious Ringing Rocks ~

Pennsylvania is dotted with sites where rocks ring when struck by a hammer. These include the Stony Garden (Haycock, Bucks County), the Devil’s Race Course (Franklin County), and others in the South Mountain region and at Pottstown. When the rocks are struck with a hammer or another rock, they sound as if they are metal and hollow and ring with a sound similar to a metal pipe being struck. Ringing Rock Park is located near the town of Pottstown in Pottsgrove Pa. .
