Ringing Rocks, Man & Boys, Upper Black Eddy, PA
Additional Details:
| These 3 1/2 acres of conglomerate stone and mineral formations can be found 2 1/2 miles west of the Delaware River at Upper Black Eddy. The rocks produce a variety of bell-like sounds when hit with a hammer. It is thought the rocks are a result of the eruption of dykes in the earth's crust. |
