Question: Hewn ruthlessly from the earth by water over 270million years, these stone structures are a testament to the power of the natural world. The pillars, arches and columns rise hundred of feet into the air over a vast region of southern China, striking awe into observers who have flocked to the area for thousands of years. Known as karsts, the limestone structures - captured in these images for National Geographic Magazine - are created when water forces fissures, sinkholes, cracks and caverns into the soft rock, leaving only a series of monoliths above ground. Vast: Jaw-dropping limestone 'karsts' formed by erosion over 270million years soar hundreds of feet into the air across a huge region of southern China. Pictured, climber Emily Harrington takes the hard way up Moon Hill, an arch which was formed from the remains of a collapsed cave. Sightseers can take an easier dirt track. Awe: The enormity of the structures is clear compared to the size of the cavers ascending them, from a limestone spire in the Enshi canyon (left) to the Great Arch in Ziyun Getu He Chuandong National Park (right). Seeing these sights can be much easier, as a new glass elevator delivers less intrepid tourists to the foot of the arch. China's Stone Forest is one of the. largest, with huge arches which once belonged to cave systems but now. protrude awkwardly above the lush green hills around. Covering an estimated half a million square kilometres, south China's is one of the largest and most significant in the world. While. limestone structures are common, only in a humid, tropical environment. can there be enough movement of water to create such dramatic change,. and form structures which have earned the South China Karst recognition. as a UNESCO World Heritage Site. But. just as with an iceberg, what can be seen in these photographs is only. the tip. The flowing water has not only carved up the landscape above. the ground, but has also transformed it below. South. China is home to some of the largest caves in the world, which even now. are still being mapped and explored by researchers from around the. world. Heading the charge. is a team led by Andy Eavis, the chairman of the British Caving. Association who has been traveling to China for more than 30 years. Otherworldly: The landscape was formed by water in the humid region seeping in through cracks in porous rock and gradually opening up sinkholes, fissures and caves. All work and no play...: Those pictured have devoted their careers to exploring and mapping the hostile cave landscape down below - but do come up for air occasionally. Map: Beneath southern China's landscape researchers have discovered some of the largest underground chambers in the world. In 2013 a British-led expedition used a laser scanner to map the Miao Room of Gebihe, pictured, whose maximum height is 627 feet. A passenger jet is shown for scale. The images are from the July issue of National Geographic magazine. He and his explorers have used. pioneering laser scanners to map the complex, unstable systems in. unprecedented detail, including the Miao Room of the Gebihe cave system -. since confirmed as the second-largest known cavern in the world. Despite. its entrance from the outer world comprising just a narrow, unobtrusive. gap in stone in the forest, it has a maximum height of 627 feet. The. cavern must be explored in hostile conditions - including high humidity. and a lack of any natural light - using a mixture of computer. technology and old-fashioned caving bravery. With. fissures and sharp points of rock, a wrong step could mean injury or. death, and the cavern is so large it could fit a fleet of jumbo jets. with plenty of room to spare. Other. caves are less formidable. In one part of the region, an entire village. of 21 homes - with no need for rooves - is situated inside a cavern. together with a primary school, a basketball court, and an increasing. stream of tourists. More still have been made safe for people to explore without the risk of losing their hats. It. is not all work and no play for the explorers. Some feature in these. photos, where they take time off from their caving work to ascend the. other side of China's fantasy landscape. That. is despite there being far more tourist-friendly ways to ascend the. limestone structures, which are mainly in China's Yunnan, Guizhou and. Guangxi provinces. One, the. Great Arch in Ziyun Getu He Chuandong National Park, includes a glass. elevator which delivers the less intrepid to the foot of the arch so. they do not have to climb. It is a vision of the future - and it's predicted the caves will be next. With. China becoming one of the fastest-growing economies in the world,. tourists from other parts of the vast nation are already streaming. underground - though how long it will take to install a glass lift there. remains to be seen. The images are from the July issue of National Geographic magazine.

What are highlight points for this article?
Answer: 1. The limestone structures, known as karsts, have been formed over 270 million years in southern China due to water erosion, creating awe-inspiring pillars, arches, and columns that rise hundreds of feet into the air.

2. South China's karst landscape is one of the largest and most significant in the world, covering an estimated half a million square kilometers, and has been recognized as a UNESCO World Heritage Site.

3. The karst formation process occurs in humid, tropical environments where water movement leads to the creation of dramatic structures.

4. South China is home to some of the world's largest caves, which are still being explored and mapped by researchers from around the globe.

5. Andy Eavis, chairman of the British Caving Association, leads a team that uses innovative laser scanners to map complex and unstable underground cave systems.

6. The Miao Room of the Gebihe cave system, confirmed as the second-largest known cavern in the world, was mapped using laser scanners in 2013.

7. Some of the region's caves have been adapted to accommodate human settlements, including an entire village of 21 homes, a primary school, and a basketball court.

8. Tourist-friendly ways to explore the limestone structures have been developed, such as a glass elevator at the Great Arch in Ziyun Getu He Chuandong National Park.

9. As China's economy grows rapidly, a higher number of domestic tourists are visiting the caves, suggesting further development of these sites for visitors in the future.
