There is a mysterious rock-filled area on top of a hill in Pennsylvania, about which no one is aware of why or how these rocks appeared here. The rocks are said to have formed over a period of thousands of years due to the erosive action of water. These rocks are a mystery to the people as these rocks produce a mesmerizing sound like a musical instrument when struck lightly with a hammer and not only this, each rock has its own distinct sound. Each boulder gives off a "bell-like tone" and the size and shape of the boulder affect the tone. But the surprising thing is that if these rocks are removed from this site, this unique quality will no longer remain there in the rocks.

Spread over 128 acres, the park is called 'Ringing Rocks' park with a seven-acre section covered in musical boulders. People usually love to visit this site and enjoy this rare geological experience a lot. These large stones emit a distinctive metallic sound and have been known to the locals for years, who have been pounding them with hammers and stones. The sound emanating from these rocks can confuse anyone, making anyone think whether these are really mountains made of stone or something else. Many such rocks are also found in several other places of the world, like in India you will find such rocks having been used as pillars in many temples.

Scientists and geologists have been researching the ringing ability of the rocks for years, but even after much research, it could not be ascertained why these rocks actually ring. Scientists have different views on this. Some say that these "ringing rocks" are formed from a group of diabase sills that are found in the earth's crust and that these sounds are produced due to the distinct structure of each rock. According to the second theory, on hitting a rock, a low-frequency sound is generated that we cannot hear. But by repeatedly hitting multiple rocks, all the frequencies interact with each other and get increased, giving a ringing bell-like sound. But there is no complete certainty on this theory as well, so this mystery persists even today.
