Tepui
A tepui , or tepuy (), is a member of a family of table-top mountains or mesas found in northern South America, especially in Venezuela, western Guyana, and northern Brazil. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Notable tepuis include Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

Gran Sabana
La Gran Sabana (, ) is a region in southeastern Venezuela, part of the Guianan savanna ecoregion. The savanna spreads into the regions of the Guiana Shield, Guiana Highlands and south-east into Bolívar, Venezuela, Bolívar State, extending further to the borders with Brazil and Guyana. The Gran Sabana has an area of and is part of the second largest List of national parks of Venezuela, National Park in Venezuela, the Canaima National Park. Only Parima Tapirapecó National Park is larger than Canaima. The average temperature is around , but at night can drop to and in some of the more elevated sites, depending on weather, may drop a bit more. The location offers one of the most unusual landscapes in the world, with rivers, waterfalls, gorges, deep and vast valleys, impenetrable jungles, and savannas that host large numbers and varieties of plant species, a diverse fauna, and the isolated table-top mesas locally known as ''tepuis''.

Angel Falls
Angel Falls (; Pemon: ''Kerepakupai Merú'' or ''Parakupá Vená'') is a waterfall in Venezuela. It is the world's tallest uninterrupted waterfall, with a height of , and a plunge of . The waterfall drops over the edge of the Auyán-tepui mountain in the Canaima National Park ( Spanish: Parque Nacional Canaima), a UNESCO World Heritage Site in the Gran Sabana region of Bolívar State. The height figure, , mostly consists of the main plunge but also includes about of sloped cascade and rapids below the drop and then a plunge downstream of these talus rapids. The falls are along a fork of the Río Kerepacupai Merú which flows into the Churún River, a tributary of the Carrao River, itself a tributary of the Orinoco River. With regard to overall height, a revisited validation of waterfall measurements is not available, and there is still uncertainty whether Angel Falls or South Africa's Tugela Falls is the tallest (both measurements were taken at considerable distance ...

Mount Roraima
Mount Roraima (; ) is the highest of the Pacaraima chain of tepuis (table-top mountain) or plateaux in South America. It is located at the junction of Brazil, Guyana and Venezuela. A characteristic large flat-topped mountain surrounded by cliffs high. The highest point of Mount Roraima is located on the southern edge of the cliff at an elevation of in Venezuela, and another protrusion at an elevation of at the junction of the three countries in the north of the plateau is the highest point in Guyana. The name Mount Roraima came from the native Pemon people. ''Roroi'' in the Pemon language means "blue-green", and ''ma'' means "great". Leaching caused by intense rainfall has shaped the peculiar topography of the summit, and the geographical isolation of Mount Roraima has made it home to much endemic flora and fauna. Western exploration of Mount Roraima did not begin until the 19th century, when it was first climbed by a British expedition in 1884. Yet despite subsequent expedi ...

Guianan Savanna
The Guianan savanna (NT0707) is an ecoregion in the south of Venezuela, Guyana and Suriname and the north of Brazil. It is in the Amazon biome. The savanna covers an area of rolling upland plains on the Guiana Shield between the Amazon and Orinoco basins. It includes forested areas, but these are shrinking steadily due to the effect of frequent fires, either accidental or deliberate. The ecoregion includes the Gran Sabana region of Venezuela. Location The ecoregion includes three large unconnected areas totaling . The main section is in southeast Venezuela, the Brazilian state of Roraima and western Guyana. To the southeast a smaller section is in the north of the Brazilian state of Pará extending into the south of Suriname. The most eastern and smallest section is in the Brazilian state of Amapá, stretching north from Macapá. There are small isolated fragments to the north of the main section in the Pakarima foothills in Guyana. The main section includes the Gran Sabana regi ...

Kukenán-tepui
Kukenán, also known as Matawi or Cuquenán, is a tepui in Bolivar State, Bolívar State, Guayana Region, Venezuela. It has an estimated surface area of 2185 hectares (equivalent to 21.85 square kilometres). It is high and about 3 km (1.9 mi) long. Cuquenan Falls, Kukenan Falls, which is high, is located at the south end of the tepui. Kukenán is located in Canaima National Park. Next to Kukenán, to the southeast, is Mount Roraima, a better known tepui. Kukenán is more difficult to climb, so it is ascended much less frequently than Mount Roraima. Canaima National Park is also home to the highest waterfall in the world, which is located in Auyán Tepui. Scenery on top of Kukenán provided inspiration for the 2009 film ''Up (2009 film), Up''.

Guianan Highlands Moist Forests
The Guayanan Highlands moist forests (NT0124) is an ecoregion in the south of Venezuela, the north of Brazil, and also within Guyana, Suriname, and French Guiana. It is in the Amazon biome. It encompasses an upland region with diverse fauna and flora, which contains dramatic tepuis, or sandstone table mountains. The region has been inaccessible in the past and is generally fairly intact, apart from the north and northeast where large scale agriculture, ranching and mining operations are steadily encroaching on the ecosystem. New roads are opening the interior to logging, and planned dams will have a drastic impact on the riparian zones. Location The ecoregion includes parts of southern Venezuela, western and southern Guyana and northern Brazil, with scattered portions in Suriname and French Guiana. It extends into eastern Colombia. It has a total area of . The ecoregion lies on the Guiana Shield, an ancient upland area between the Amazon and Orinoco basins. It is surrounded by l ...

Pemon
The Pemon or Pemón (Pemong) are Indigenous people living in areas of Venezuela, Brazil, and Guyana.See pp.112,113 and 178 of ''Venezuela: the Pemon'', in '' Condé Nast Traveler'', December 2008. The Pemon people are divided into many dialects and traditions, which are Arekuna, Kamarakoto, and Taurepang. People The Pemon are part of the larger Cariban language family, and include six groups including the Arekuna, Ingarikó, Kamarakoto, Tualipang, Mapoyo and Macushi/Makushi (Macuxi or Makuxi in Brazil). While ethnographic data on these groups are scant, Iris Myers produced one of the most detailed accounts of the Makushi in the 1940s, and her work is heavily relied upon for comparisons between historical and contemporary Makushi life. The Pemon were first encountered by westerners in the 18th century and converted by missionaries to Christianity. Their society is based on trade and considered egalitarian and decentralized, and in Venezuela, funding from petrodollars have help ...

Cerro Autana
Cerro Autana (Autana Mountain) is a geological formation located at the western portion of the Guiana Shield in the Estado Amazonas, Venezuela near the Colombian border. It is characterized by a narrow base, a flat top, and almost vertical walls. Its top is at approximately . It belongs to the formations known as tepuis which are characteristic flat-top mountains of the Guiana Shield. Cerro Autana (Wahari-Kuawai) plays the role of the "tree of life" in the oral history and lore of the Piaroa people, Piaroa Indians who inhabit the region. The first Europeans to visit the region around Cerro Autana were Alexander von Humboldt and Aimé Bonpland in 1800. During 1852-1854 Richard Spruce and Alfred Russel Wallace made numerous observations and botanical collections. Cerro Autana is the landmark of the region of Autana which encompasses the Cerro Autana itself, a smaller adjacent mountain often referred to as the “Autanita”, the Cuao, Autana, and Umaj-ajé rivers and Lake Leopoldo ...

Table (landform)
A tableland is an area containing elevated landforms characterized by a distinct, flat, nearly level, or gently undulating surface. They often exhibit steep, cliff-like edges, known as escarpments, that separate them from surrounding lowlands. Depending on either their size, other physical characteristics, or geographic location, the landforms comprising a tableland are individually referred to by a number of names including butte, mesa, plateau, potrero, tepui, or tuya. A homologous landform under the sea is called either a tablemount or guyot. Sedimentary tablelands Sedimentary tablelands are tablelands that typically have developed from the erosion of coarse-grained, clastic, sedimentary rocks in the form of relatively flat-lying sandstones and conglomerates that have not been strongly deformed by tectonics. The primary control on the geomorphology of sedimentary tablelands is the dip of the layers of the sandstones, conglomerates, and associated sedimentary strata. Sedim ...
