A team of Chinese scientists has discovered a giant new sinkhole with a forest at its bottom. The sinkhole is 630 feet (192 meters) deep, according to the Xinhua news agency, deep enough to just swallow St. Louis' Gateway Arch. A team of speleologists and spelunkers rappelled into the...
In May, they discovered the sinkhole through satellite images and drone photography during a field survey in the region, together with three caves in the sinkhole and a well-preserved primitive forest. In an article posted on the institute's website, Zhang Yuanhai, a senior engineer with the ...
Southern China sinkhole discovered, home to towering ancient trees Experts discover 'primative forest' growing at the base of the sinkhole A massivesinkholewas discovered in southernChinawith ancient trees over 130 feet in length growing at the bottom, according to reports. The sinkhole, one of 30...
A cave exploration team has discovered a giant karst sinkhole in Leye County, south China's Guangxi Zhuang Autonomous Region, bringing Leye's number of such sinkholes to 30. Zhang Yuanhai, a senior engineer with the Institute of Karst Geology of China Geological Survey, said the sinkhole, ...
Zhang said that there are three big caves in the wall, which are presumed to be the remains of the early evolution of the sinkhole. The bottom of the sinkhole has a well-preserved primitive forest. Chen Lixin, leader of the Guangxi 702 cave expedition team, said the ancient trees growing...
This sinkhole has vertical walls and a forest at its bottom floor. Florida is a common place for sinkholes too occur. The bedrock is limestone and easily dissolved by groundwater, resulting in dissolved ground. They are not usually deadly but people have been swallowed up - including one ...

To earn this name the hole must be at least 100 meters deep and wide, with vertical walls and with a cave river below. There are some 75 tiankengs in the world, most of them in China. The largest one isXiaozhai tiankeng(Chongqing, China): an incredible 662 meters deep and up to 53...
Hidden beneath the karst mountains of Leye County in southern China are some of the deepest sinkholes on the planet. In Chinese they're known as "tiankeng," or heavenly pits, a name that poetically alludes to the immense size of these depressions that dwarf those found in Europe and the...
Natural sinkholes are mainly observed in regions with large deposits of salt, limestone, and carbonate rocks. The accurate prediction of the location and time of the occurrence of these sinkholes is rather difficult [4]. Groundwater extraction, construction in adjoining areas, and leakage in ...
