A massive sinkhole was discovered in southern China with ancient trees over 130 feet in length growing at the bottom, according to reports.
The sinkhole, one of 30 found in China's Guangxi Zhuang Autonomous Region, measures over 1,000 feet in length, 490 feet in width and nearly 630 feet in depth, the Xinhua news agency reported earlier this month.

Experts classified the sinkhole as "large" with three cave entrances in the chasm.
The sinkhole was formed in "karst terrain," which means rock below the surface can easily be dissolved by groundwater circulating through the bedrock, according to the U.S. Department for Interior.
The three interior caves are believed to have formed during earlier occurring erosion.
The sinkhole's bottom is lined with a "well-preserved primitive forest" with the trees growing up towards the sun, according to the local news agency.
Shade plants were reported to be growing as high as an adult's shoulders, leader of the Guangxi 702 cave expedition team, Chen Lixin, told the publication.

The first expedition of the cave was completed earlier this month after experts scaled down more than 300 feet and hiked for several hours before reaching the base of the sinkhole.
The discovery of the latest sinkhole is not an anomaly.
Southern China, like areas in Mexico, Peru and Australia, are home to dramatic sinkholes.

A massive 630ft-deep sinkhole has been found in China in which a stunning ancient forest range has been discovered by researchers with trees as tall as 131ft (40m) and could include species that have not been seen before.
Cave explorers came across the sinkhole near Ping’e village in Leye County of the Guangxi Zhuang Autonomous Region earlier this month.
The sinkhole is 630ft (192m) deep and measures 1,000ft (304m) in length and 490ft (149m) in width, according to the Xinhua news agency.
The discovery was classified as “large” and experts hiked for several hours before reaching the base of the sinkhole and found three cave entrances.
The sinkhole’s bottom is lined with a “well-preserved primitive forest” with the trees growing up towards the sun, according to experts quoted by the news agency.
Chen Lixin, who led the cave expedition team, told Xinhua that the dense undergrowth on the sinkhole floor was as high as a person’s shoulders and that some of the ancient trees at the bottom were 131ft (40m) tall.
“I wouldn’t be surprised to know that there are species found in these caves that have never been reported or described by science until now,” Mr Lixin said.
China’s Guangxi region is known for its beautiful and sometimes dramatic karst formations.
Leye County alone, where this current sinkhole was discovered, is home to a number of such sinkholes. The discovery of this new one has brought the number of sinkholes in this county to 30, reported Xinhua.
Karst landscapes are formed primarily by the dissolution of bedrock, George Veni, the executive director of the National Cave and Karst Research Institute (NCKRI) in the US, told Live Science.
“Because of local differences in geology, climate and other factors, the way karst appears at the surface can be dramatically different,” he said.
“So in China you have this incredibly visually spectacular karst with enormous sinkholes and giant cave entrances and so forth,” he added.
“In other parts of the world you walk out on the karst and you really don’t notice anything. Sinkholes might be quite subdued, only a metre or two in diameter. Cave entrances might be very small, so you have to squeeze your way into them.”

Cave explorers discover ‘heavenly' sinkhole surprise living down below

When we think of sinkholes, images of deep-pitted wells of buckling and sunken asphalt come to mind as they swallow up chunks of earth and everything with it.
Gaping large and dramatic enough, they often draw the curious onlookers eager for a peek at what might be lurking far below the surface.
But peering into one recently discovered sinkhole in the hilly outlying regions of southern China, one finds a lush forest down below with ancient towering trees. It's a place they call "tiankeng" in Mandarin, meaning "heavenly pit."
The gaping hole, measuring 1,003 feet (306 meters) long and 492 feet (150 meters) wide, was discovered by cave explorers on May 6 in China's Guangxi Zhuang Autonomous Region, near Ping'e village in the county of Leye. What made it all the more mysterious were the three smaller cave entrances an expedition team stumbled upon once inside the 623-foot-deep cavernous pit.
The group of cave scientists and explorers -- called "speleologists" and "spelunkers" -- rappelled down to the bottom of this enormous chasm to document the flora and other life that has flourished and taken hold in the space as the sinkhole's opening slowly grew larger and larger "over millennia," according to experts.
Chen Lixin, who led the cave expedition team, described the plentiful and ancient, 140-foot-tall trees growing at the bottom with their branches stretched out toward the sunlight and the dense undergrowth on the sinkhole floor that is as high as a person's shoulders.
Scientists believe the subterranean habitat may even harbor some still unknown species.
"I wouldn't be surprised to know that there are species found in these caves that have never been reported or described by science until now," George Veni, executive director of the National Cave and Karst Research Institute in New Mexico, told AccuWeather.
Such unknowns are what lend to their mysterious nature.
"You don't know what you're going to find in each corner, and sometimes we are surprised and occasionally something breaks through our own expectations," he added.
For scientists and researchers who devote their lives to studying sinkholes and caves, Veni said, "they inspire us and challenge us to learn and explore more."
"It's interesting that we've gone from living in caves to now studying and exploring them," Veni mused.
Sinkholes and caves are rather common in the southern parts of China due to the vast karst topography throughout the region.

Karst landscapes form usually when rainwater dissolves certain types of rocks, creating ridges, fissures, sinkholes and the like.
In fact, these towering karst formations, which range from sinkholes to rock pillars to natural bridges, have earned the region a UNESCO world heritage site designation that protects the area.
"The geologic conditions are just right in China" to create such wonders of the Earth, said Veni.
"In China, you have this incredibly visually spectacular karst with enormous sinkholes and giant cave entrances and so forth," Veni added.
This most recent find is the 30th sinkhole to have been discovered in this region of China, according to the Xinhua news agency. The country also holds the honor of being home to the largest sinkhole. Located in Xiaozhai Tiankeng, the sinkhole there is 2,100 feet deep, 2,000 feet long and 1,760 feet wide and includes a waterfall within its depths.
The United States, he noted, claims 25% of the world's karst caves and sinkholes, "but they're not as dramatic."
"Sinkholes might be quite subdued, only a meter or two in diameter. Cave entrances might be very small, so you have to squeeze your way into them."
And the karst isn't just pretty spectacular to look at. It provides a basic necessity for millions of people worldwide. Veni said about 700 million people depend on karst aquifers as their primary or sole water source.
2021-22 marked the first-ever International Year of Caves and Karst that has featured 500 events around the world.

Giant sinkhole found in China has hidden forest with ancient trees growing at its floor

Wed, May 18, 2022
Cave explorers in southern China may have found the modern-day equivalent of The Lost World.
At the bottom of the newly discovered 630-foot deep sinkhole lies a hidden forest, lush with shoulder-high flora and tall trees.
Researchers also think there may be new species of animals and plants within the sinkhole, which is made up of three caves and measures 5 million square meters, the equivalent of 2,000 Olympic swimming pools.
The sinkhole was discovered in the Guangxi Zhuang Autonomous Region, near Ping'e village in the county of Leye, according to the Chinese government's official news agency Xinhua, The area of southern China is known for its caves, sinkholes, and karst forests, limestone formations that populate the landscape.

Leader of the cave exploration team, Chen Lixin, told Xinhua the ancient trees growing at the bottom of the sinkhole are nearly 130 feet tall – taller than most oak trees. Dense shade plants grew as tall as the explorers' shoulders, Lixin said.
"I wouldn't be surprised to know that there are species found in these caves that have never been reported or described by science until now," Lixin said, according to Live Science.
These type of sinkholes and caves could harbor new flora and fauna, international cave expert George Veni told Live Science. "This is cool news," said Veni, who was not involved in the discovery or exploration of this new cave. He is the executive director of the National Cave and Karst Research Institute in Carlsbad, New Mexico.
Sinkholes and caves are created over time as water dissolves limestone, according to the institute. Large sinkholes can have small ponds and fields of plants at the bottom.
Zhang Yuanhai, a senior engineer with the Institute of Karst Geology of China Geological Survey, categorized the find as a large sinkhole, with a well-preserved primitive forest at the bottom, Xinhua reported.
The explorers completed their expedition on May 6, emerging from the sinkhole after rappelling more than 100 meters down (about 330 feet) and walking several hours to reach its bottom, according to Xinhua. The sinkhole measures about 1,000 feet in length, 500 feet in width and 630 feet in depth.
That such a sinkhole might be found in China is not a big surprise because the region has "this incredibly visually spectacular karst with enormous sinkholes and giant cave entrances and so forth," Veni told Live Science.
Zhang Yuanhai was part of a team that explored an even larger sinkhole found in Guangxi five years ago.
This latest discovery brings the region's number of such sinkholes to 30, Xinhua reported. Mexico and Papua New Guinea are other countries where sinkholes are frequently found.
