China: Scientists find 192m-deep sinkhole with ‘well-preserved primitive forest’

Cave explorers in China have found a huge sinkhole with a forest hidden inside in Guangxi, southern China.

At its bottom, scientists found trees up to 40 meters high – for comparison, coconut trees are usually 20-30 meters high – and the ground is covered with dense vegetation, Chinese state media reported. Xinhua.

With this, the number of such sewers in Leye County has reached 30. However, what distinguishes this stream is its size – it is 306 m (1,003 ft) long, 150 m (492 ft) in width and 192 m (629 ft) in the depth. Its volume exceeds 5 million cubic meters.

Citing Zhang Yuanhai, chief engineer at the Karst Geology Institute of China Geological Survey, China Media House said the building has three caves in its walls and a “well-preserved primitive forest” at its bottom.

Chen Lixin, head of the Guangxi 702 Cave Expedition team, said that the ancient trees growing at the bottom were about 40 meters high, and the dense shade plants reached one’s shoulders. Xinhua.

According to reports, a team of scientists sped more than 100 meters into the stream and traveled for hours to reach its bottom. They concluded the exploration on May 6 and returned to safety.

The US Geological Survey website defines a sinkhole as “a depression in the earth with no natural external surface drainage.” They are typically found in “karst terrain” where rocks below the Earth’s surface are soluble in groundwater.

Aside from China, Mexico, Papua New Guinea, and parts of the United States, holes have been reported.
