The Chan Da Ya, located in the Qiannan Bui-Miao Autonomous Prefecture of China’s Guizhou Province, is a mysterious place where a rock formation lays perfectly round stones every 30 years.
This phenomenon has puzzled geologists for decades as it has yet to be fully explained.
The rock, which is only 2.7 meters tall, is a strongly blurred formation with a surface covered in dozens of round and oval stones of different sizes.
As the rock is destroyed, the heaviest stones fall, but new ones appear in their place, as reported by the locals.
This occurrence happens about once every 30 years. Geologists have conducted tests on the Gandeng mountain, which is made up of dense and solid deposits.
However, there is a special area of limestone mountain mass that is very easy to break.
Over time, these stones seem to rise to the surface and give the appearance of the rock laying eggs.
The question remains as to why the limestone mass that formed in the Cambrian era, some 500 years ago, is still preserved.
Additionally, the slope of Chan Da Ya is scattered with strange round stones, adding to the mystery of the place.
Despite the efforts of geologists, the secret of the Chan Da Ya remains unsolved.
