Slide 2 A. GARCIA PRODUCTIONS PRESENTS HANG SON DOONG CAVE THE LARGEST CAVE IN THE WORLD HANG SON DOONG CAVE THE LARGEST CAVE IN THE WORLD Slide 3 In April 2009, in the Phong Nha-ke Bang National Park en De Quang Binh province in Vietnam, an enormous cave was discovered. It measures 6.5 kilometers long, widths of 150 meters, and is 200 meters high in places. Forming part of twenty new caverns identified by a British exploration group, it is the largest known cave in the world. The subterranean river in the cavern stopped explorers from going further; the extent of the cavern can only be estimated using a flashlight. The cave will be the subject of further exploration. A local had discovered the cave in 1991, but he couldnt remember just where it was. Around March and April of 2009, he assisted the explorers in crossing 10 kilometers of forest to get to the mouth of the cave. Given the difficulty in getting to the mouth of the cave, only scientists will have access to the discovery for the time being. HANG SON DOONG Slide 4 NHA-K BNG NATIONAL PARK Slide 5 Slide 6 Slide 7 Slide 8 Slide 9 Scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted an expedition to PHONG NHA-KE BANG from April 10-14, 2009. Slide 10 It takes six hours trudging through the jungle to arrive at the mouth of the cave. Slide 11 Slide 12 Slide 13 After descending a large chamber, it is necessary to cross two subterranean rivers to get to the main passageway of Doong Hang Fils. To give you an idea of the immense size of the space, look at the person with a light-hat standing on the round hill in the lower center. Slide 14 Located in the Phong Nha-KeBang, near the Loation border, the cavern forms part of a web of 150 caves in the Anamita Mountains. Many of the caverns still have not been explored. Slide 15 Slide 16 Slide 17 Slide 18 One of the rooms of the cavern could accommodate a New York skyscraper. There is a jungle IN the cavern. There are even clouds. Slide 19 National Graphic sent sent a team to chart the cave in 2010. The magnificent photographs of Carsten Peter were published in the January 2011 issue of the magazine. Slide 20 Explorers were stunned by a gigantic petrified limestone cascade shaped by water. Slide 21 Slide 22 The cavern contains dry ponds near the Garden of Eden in Hang Fils Doong. They contain an exceptional collection of spherical rocks, formed drop by drop over centuries, in the form of calcium crystals surrounded by grains of sand that grow with time. Slide 23 The principal room of Fils Doong is 5 kilometers long, is 200 meters high, and 150 meters wide. Slide 24 Slide 25 Slide 26 Slide 27 Slide 28 Slide 29 The cave had never been explored, even by the locals partly because the entrance was rather small in comparison to other Vietnamese caves (10 meters high by 30 meters wide), but also because the large subterranean river emits an errie sound. Slide 30 Sunken roof mini-jungle 300 meters below the surface. Slide 31 A huge sun ray falls into the cave like a waterfal. In the foreground is a giant stalagmite. Slide 32 When part of the jungle roof of the cave gave way long ago, it created a chasm with its own ecosystem below. A new species of insect was found in this area. It has no pigment and is blind. The plants have adopted to the change in climate. When part of the jungle roof of the cave gave way long ago, it created a chasm with its own ecosystem below.

Slide 34 The chasms were created when the roof of the cave collapsed. The daylight enters the cave, creating unique ecosystems. Slide 35 Slide 36 The new room measures 200 meters long by 150 wide approximately twice the previous record of Deer Cave in Malasia. Slide 37 This wide opening was created by the torrential tropical rains at the opening. Slide 38 A 300 meters below the jungle surface is a mini-jungle at the bottom of the chasm. Slide 39 Slide 40 After six kilometers of exploration, the route is obstructed by a gigantic calcite rock, cristened The Great Wall of Vietnam. | Slide 41 Climbing The Great Wall of Vietnam is proof that this is the far end of the cavern.
