Geological Mystery: Rocks That Ring When Hit
Upper Black Eddy, PA 18972
United States of America
A geological mystery where a large deposit of boulders in a forest clearing ring when you hit them with another object.
Located in Bucks County, PA in Upper Black Eddy is a bizarre pit of large rocks that reverberate as if they were metal when you strike them. Scientists have been unable to explain why the rocks do this but that hasn't stopped people from making wild guesses from fairies to UFOs. Ringing rocks is a phenomenon that occurs in various places in the country but there seems to be a concentration of them in Upper Black Eddy in this field.
The field of boulders is unexpected as you park your car in an entrance to what looks like a normal park trail. About 200 feet into the trail, the woods open up to reveal what looks like what must have been at one point a river. Instead of water, you have huge rocks--lots of them.
Remember to bring another rock to hit the boulders with. Many will suggest bringing a hammer but a regular metal hammer will just make the ringing harder to hear. Not ALL the rocks ring, just some of them so you have to hop around the boulders. The ringing will sound like if you hit a large piece of metal and come in different tones. Some are more obvious than others but you will be able to hear the difference between hitting a regular rock and a "ringing rock."
Some have suggested that there's a higher concentration of metals in the rocks that do ring but there hasn't been conclusive evidence that suggests this. Also, researchers have found that the rocks will continue to ring even after they are removed from the site. Clearly, it's something about the rocks themselves that cause them to ring.
The river of rocks continues on for about a mile and you can follow the path by jumping on and off rocks. However, keep in mind that the area is not maintained or supervised. Some of the boulders are a little loose or worn away from people stepping on them or hitting them over and over again. Watch your step and be careful. There isn't a paved path or anything. Also, try and go on a nice day, water makes the rocks slippery.
