30th giant karst sinkhole discovered in south China's Guangxi

A cave exploration team has discovered a giant karst sinkhole in south China's Guangxi Zhuang Autonomous Region, bringing the number of such sinkholes in the county to 30. The sinkhole measures 306 meters in length, 150 meters in width and 192 meters in depth, with its volume exceeding 5 million cubic meters, and can be categorized as a large sinkhole. The bottom of the sinkhole has a well-preserved primitive forest. The newly found one will help the team carry out further comparative studies, which may expand their understanding of the karst landform in the future.
