If you’ve never heard of an egg-laying mountain, you probably don’t know about Chan Da Ya, a mysterious cliff in China that reportedly lays perfectly round or oval stone eggs every 30 years.
Located in Qiannan Buyi and Miao Autonomous Region, China’s Guizhou Province, Chan Da Ya – Mandarin for “egg laying cliff” – has been puzzling geologists for decades. The 9ft high and 65ft long heavily eroded formation has an uneven surface dotted with dozens of round and oval-shaped stones of various sizes. As the elements continue to eat away at the cliff, the harder “eggs” become even more exposed and eventually fall out of their natural sockets. According to the people of the nearby Gulu village, Chan Da Ya takes 30 years to lay its strange stone eggs.
