Cerro Sarisariñama is a  tepui , a flat-topped mountain in  Jaua-Sarisariñama National Park  at the far south-west of  Bolívar State ,  Venezuela , near the border with Brazil . Its altitude range is 300–2,350 metres. The name of the mountain originates from the tale of local  Ye'kuana  Indians about an evil spirit living in caves up in the mountain and devouring human flesh with a sound "Sari... sari...". The tepui is in one of the most remote areas in the country, with the closest road being hundreds of miles away. Similar to other tepuis, Sarisariñama consists of  quartzite  of the  Roraima  formation, belonging to  Paleoproterozoan . The summit area of Sarisariñama tepui is 546.88 km² and the slope area is 482 km². Sarisariñama is unique among tepuis, with a 15–25 metre-high forest fully covering the top of it. This isolated ecosystem is especially rich with numerous endemic species of plants and animals. The most distinctive features of this tepui ar

Mount Roraima ( Spanish :  Monte Roraima   [ˈmonte roˈɾaima] , also known as  Tepuy Roraima  and  Cerro Roraima ; Portuguese :  Monte Roraima   [ˈmõtʃi ʁoˈɾajmɐ] ) is the highest of the  Pakaraima  chain of  tepui   plateaus  in  South America . First described by the English explorer  Sir Walter Raleigh  in 1596, its  31 km 2  summit area is bounded on all sides by cliffs rising 400 metres (1,300 ft). The mountain also serves as the triple border point of  Venezuela  (claiming 85% of its territory),  Brazil  (5%) and  Guyana  (10%). Mount Roraima lies on the  Guiana Shield  in the southeastern corner of Venezuela's 30,000-square-kilometre (12,000 sq mi)  Canaima National Park  forming the highest peak of Guyana's Highland Range. The tabletop mountains of the park are considered some of the oldest geological formations on  Earth , dating back to some two billion years ago in the  Precambrian . The highest point in Guyana and the highest point of the Brazilian state of 

The  Waitomo Caves  is a village and  solutional cave  system forming a major tourist attraction in the northern King Country region of the  North Island  of  New Zealand , 12 kilometres northwest of  Te Kuiti . The community of Waitomo Caves itself is very small, though the village has many temporary service workers living there as well. The word  Waitomo  comes from the  Māori language   wai  meaning water and  tomo  meaning a doline or  sinkhole ; it can thus be translated to be  water passing through a hole .   The caves are formed in  Oligocene   limestone . The limestone landscape of the  Waitomo District  area has been the centre of increasingly popular commercial  caving  tourism from as early as 1900. Initially mostly consisting of impromptu trips guided by local  Māori , large sections of cave near Waitomo Caves were later taken over by  the Crown  and managed as a (relatively genteel) tourism attraction from 1904 onwards. Today, a number of companies, large and sma

Salar de Uyuni (or Salar de Tunupa) is the world's largest  salt flat  at 10,582 square kilometers (4,086 sq mi). It is located in the Daniel Campos Province in  Potosí  in southwest  Bolivia , near the crest of the  Andes  and is at an elevation of 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of  brine , which is exceptionally rich in  lithium . It contains 50 to 70% of the world's lithium reserves, which is in the process of being extracted. The large area, clear skies, and the exceptional flatness of the surface make the Salar an ideal object for calibrating the  altimeters  of Earth observation satellites. The Salar serves as the major transport ro

Jiuzhaigou ( pronounced   [tɕjùʈʂâɪkə́ʊ] ;  Chinese :  九寨沟 ; literally: "Valley of Nine Fortified Villages";  Tibetan :  གཟི་རྩ་སྡེ་དགུ། ,  ZYPY : Sirza Degu) is a  nature reserve  and  national park  located in the north of  Sichuan  province, China. Jiuzhaigou Valley is part of the  Min Mountains  on the edge of the  Tibetan Plateau  and stretches over 72,000 hectares (180,000 acres). It is known for its many multi-level waterfalls, colorful lakes, and snow-capped peaks. Its elevation ranges from 2,000 to 4,500 metres (6,600 to 14,800 ft). Jiuzhaigou Valley was inscribed by  UNESCO  as a  World Heritage Site  in 1992 and a World  Biosphere Reserve  in 1997. It belongs to the category V (Protected Landscape) in the  IUCN  system of protected area categorization. The stunning Unesco World Heritage Site of Jiǔzhàigōu National Park is one of Sìchuān’s star attractions. More than two million people visit the park every year to gawp at its famous bluer-than-blue lake
