The Pennsylvania Natural Park has more than 500,000 sq. m. there is a Park of Ringing Stones, a strange natural phenomenon that scientists still cannot explain. Tourists are given hammers here and offered to explore the place on their own.
If you hit a stone with a hammer, a dull sound is emitted, but not in the Ringing Stones Park. Here the stones emit melodious sounds of different tones, there are even those that emit bell ringing.
Esotericists believe that this place heals, since it is from the stones that energy is sucked out and the disease goes away with it, and the road up a mountain with tall trees returns the lost energy, thus leaving the disease far behind.
Scientists have repeatedly experimented with stones, crushed them, placed them in other materials, clamped them tightly in tesques - the stones did not stop sounding, and no matter what shape or size they were. There are fist-sized stones, and there are lumps weighing several tons.
Under the microscope, it was also not possible to find the answer to this mysterious phenomenon. At first, everyone thought that the cobblestones were ringing due to dryness, they say, those stones that are in the shade sound worse, because they dry more slowly after rain. But inquisitive minds placed a ringing stone in the water and after the experiment it did not sound worse, so this theory was not confirmed.
One of the assumptions: these stones are a former meteorite. However, there are other mysterious places in the world where not only stones, but even stalactites ring, so until the nature of the stones is clarified and the cosmic origin is not proven, everything will remain in theory.
The neighboring rocks in this region are very different in color from the ringing stones, which are even painted red in places. Locals claim that in this area sometimes even the mountains sing, and the sound comes from the ground.
