The Strange Case of the Ringing Rocks

The Ringing Rocks are commonly accepted as a natural phenomenon which no one completely understands. Ringing Rocks dot the Pennsylvania (PA) landscape, and have even been used as instruments in a public performance (June, 1890 - Buckwampum Historical Society).

Ringing Rocks are formed of diabase, yet only around 1/3 of them ring. Richard Faas found that the rocks produce subaudial frequencies that cannot be heard by the human ear. Ringing Rocks are found all over the world, and scientists have no answers.
