Ringing Rocks County Park: Upper Black Eddy, Pennsylvania

Known officially as the Bridgeton Boulder Field, Ringing Rocks County Park is one of the strangest places in Pennsylvania. It's known for the unusual sound that many of the rocks make when hit by a hammer. No one really knows why the rocks make the sound when hit but in 1965, a group of scientists tested the rocks. After conducting numerous tests, they found that all the rocks do ring but often do so at tones lower than the human ear can perceive. Furthermore, the exact mechanism by which they ring still remains elusive.
In 1890, J.J. Ott gave a concert for the Buckwampum Historical Society. What made the concert so interesting wasn’t the music being played but the instrument he was playing. The instrument was made of stones that made “clear, bell-like tones” when struck by a hammer. Ott procured the musical rocks from a nearby boulder field in Upper Black Eddy, Pennsylvania, known today as Ringing Rocks Park!
