At the Chan Da Ya, a mystery location in the Guizhou Province of China, a rock formation deposits perfectly round stones every 30 years.
The Chan Da Ya is part of the Qiannan Bui-Miao Autonomous Prefecture.
Due to the lack of a complete explanation, this occurrence has baffled geologists for decades.
The rock, which stands barely 2.7 meters tall, is a heavily blurred creation with dozens of round and oval stones of various sizes covering its surface.
According to residents, the biggest stones fall to the ground when the rock is demolished, yet new ones appear in their place.
A 30-year period sees this incidence. On the Gandeng mountain, which is composed of substantial and thick deposits, geologists have performed experiments.
But, there is a particular region of the limestone mountain mass that is particularly simple to fracture.
These stones gradually appear to climb to the surface, giving the impression that the rock is laying eggs.
Why the limestone mass that originated in the Cambrian epoch, some 500 years ago, is still in tact is still a mystery.
Chan Da Ya’s slope is also covered in odd spherical stones, which adds to the location’s mystique.
Geologists have tried their best to unravel the Chan Da Ya’s mystery, but they have not been successful.
