The scientific world was stunned again after Chinese researchers released the latest findings regarding one of the most extreme geological structures on the planet — a giant natural hole 662 meters deep that hides an ancient ecosystem that has been almost untouched by humans. This phenomenon is in Fengjie, Chongqing, China, and is known as Xiaozhai Tiankeng, the deepest sinkhole in the world based on China Geological Survey data and international karst records.
Scientists discovered that the bottom of this giant ravine forms a hidden world: a subtropical forest that has survived in humid conditions, protected from direct sunlight, and isolated for thousands of years. The trees even reach a height of more than 40 meters, indicating a stable and undisturbed environment.
The geological team that went to the location stated that this structure was formed due to the collapse of layers of karst rock over hundreds of thousands of years. The valley at the bottom of the sinkhole has a unique ecosystem with a variety of plants not found on the surface. Biologists are currently studying the possibility of rare species or ancient organisms that evolved separately in the area.
This rare geological phenomenon once again confirms that the Earth still holds secrets that are not yet fully understood. This 662 meter deep ravine is not only a world record, but also a window into hidden natural history.
