| 説明 | Located in Upper Black Eddy, PA Ringing Rock County Park is the site of a geological anomaly. Many of the rocks located in this boulder field are sonorous. When struck with a hammer they resonate as if made of metal.Over the years, many have offered theories to explain the rocks strange properties. Geologists propose that the rocks contain a high metal content or have a unique crystalline structure formed under immense volcanic heat and pressure. Paranormal investigators have proposed that the rocks may be extraterrestrial or rest on a vortex of “Earth Energy.” It is also rumored that local Native American tribes thought of this as a sacred sight and collected the rocks for use in sweat lodges. |
