Xiaozhai Tiankeng, located in the heart of China’s Chongqing Province, is the world’s largest and deepest natural sinkhole, whose astonishing characteristics have made it a global wonder.
Its sinkhole is entirely naturally formed, with a depth of 662 meters and a width of 537 meters, making its vastness and depth unique worldwide. Its formation amazes geologists due to the effects of water, which have given it a distinctive shape.
Another fascinating aspect of Xiaozhai Tiankeng is its rich natural life. Its sinkhole is home to more than 1,300 species of plants and wildlife. Among its most unique animals is the clouded leopard, known to locals since ancient times. Other animals and plants found here add to the area’s biodiversity, sparking biologists’ interest.
The sinkhole formed above a cave and features an 8.5-kilometer-long underground river that flows into a beautiful waterfall. This waterfall and the river tell the story of the sinkhole’s formation. The presence of water has not only shaped the geological structure but also supported life within it.
The discovery of Xiaozhai Tiankeng has attracted not only geologists but also tourists and researchers. This sinkhole provides a rare opportunity to study environmental changes and the structure of the Earth.
Its unique biodiversity and natural beauty have turned this site into a natural laboratory, where experts can study the underground environment and its effects.
Its structure and internal ecosystem have not only given rise to local legends and traditions but also provided researchers worldwide with a unique glimpse into natural history.
