The following is a sinkhole discovered in Guangxi Zhuang Autonomous Region in 2019.
Locally, these sinkholes are called 'tiankeng', and there are as many as 30 sinkholes in Leye
On May 6, 2022, an expedition discovered a 192m-deep sinkhole that took several hours to descend to the bottom of the hole, where there were three cave entrances inside and an ancient tree 40m high. It was discovered that the branch was growing toward the sunlight shining through the sinkhole.
According to the research team, the sinkhole discovered this time is the point connecting the river flowing underground and the cave, and it is one of the largest sinkholes in the surrounding area.
Jiang Zhongcheng, a member of the expedition and a geologist, said, 'Some depressions were formed on a plateau 1000 meters above sea level, while others developed in a chain along an underground river. This discovery was made in the depression. It will have important implications for the growth process. '
