Mystery Of The Cliff That ‘Lays’ Egg-Shaped Stones Every 30 Years And Baffles Scientists May Have Been Solved

A strange cliff face that is claimed to lay ‘eggs’ has brought a small Chinese community to the media’s attention.

According to locals, the so-called “egg-laying cliff” in south-east China routinely generates enormous round pebbles weighing up to 660 pounds.

The stone eggs’ were reported to fall from the cliff once every three decades. The phenomenon has yet to be given an official explanation by scientists.

The peculiar mountain may be found in Guizhou Province, in the Gulu Zhai village, where the Shui minority has lived for over 1,000 years.

In Chinese, the ‘egg-laying cliff,’ or ‘chan dan ya’ is a 20-meter-long (66-foot) and six-meter-wide (20-foot) location on an unnamed mountain in the village a previous article on DW News.

According to legend,’ stone eggs’ would sprout from the rock face and finally fall.

The spheres have a diameter of 30 to 60 centimeters (11.8 to 23.6 inches) and can weigh up to 300 kilograms (660 pounds).

Residents consider these rock spheres lucky, and they would take them up and worship them at home.

According to a recent video broadcast on, the mature eggs’ would descend to the ground every 30 years.

According to the story, the stone eggs’ were dark blue and resembled dinosaur eggs. According to the footage, when the journalists arrived, some of the eggs had just started to expand, while others appeared to be about to drop.

There are over 100 families in the village, and they are said to have collected over 100’stone eggs.’

They believed the things would bring them good fortune and assist newlywed couples in having sons.

Even though the strange phenomena have been extensively observed in China, scientists have yet to come up with an official explanation.

The Cliff ‘lays Eggs’ for a reason.

Over the years, Chinese geologists have proposed several theories as to why the occurrence occurs. However, there have been no official announcements.

According to Dr. Wang Shangyan of Guizhou’s Bureau of Geology and Mineral Exploration and Development, the stone eggs’ were lumps created by calcium carbonate molecules in the deep sea roughly 500 million years ago. Cambrian Period.

Dr. Wang claims in his book ‘Scary Phenomena’ that the deepwater evolved into high mountains over time, and the lumps became lodged in the mountains.


The cliff looks to be giving birth to the ‘eggs’ because of the mudstone that creates the mountain’s weather faster than the lumps.

Professor Xu Ronghua of the Chinese Academy of Science’s Institute of Geology and Geophysics mostly concurred with Dr. Wang’s viewpoint.

On the other hand, Prof. Xu claimed that the lumps form silicon dioxide.

Prof. Xu explained to DW News why the objects are round: ‘A sphere has the smallest surface area compared to other shapes of the same volume.’ As a result, forming a sphere would require the molecules’ least effort compared to the other shapes.’

Prof. Xu believes that the roundness of the lumps could be due to the presence of running water.

According to him, similar events have been reported in Beidaihe, north China, and Xinjiang, north-west China.
