The sinkhole measured 306 meters (1004 feet) long, 150 meters (492 feet) wide, and 192 meters (630 feet) deep in Leye County, Guangxi Zhuang region. The cavity near Ping’e village astonishingly contained an ancient forest, home to several undiscovered tree and plant species.

An Institute of Karst Geology of the China Geological Survey team abseiled down more than 100 meters (328 feet) and took several hours to reach the pit’s bottom. They found three different entrances to the cave and measured some trees that soared nearly 40 meters (130 feet) with their branches extended towards the heavens above. Dense vegetation on the sinkhole floor grew up to shoulder height.
