Auyán Tepui, also spelled Ayan, is a tepui in Bolívar state, Venezuela. It is the most visited and one of the largest tepuis in the Guiana Highlands, with a summit area of 666.9 km2 (257.5 sq mi) and an estimated slope area of 715 km2 (276 sq mi). The uneven, heart-shaped summit plateau of Auyán-tepui is heavily inclined, rising from around 1,600 metres (5,200 ft) in the northwest to a maximum of 2,450 m (8,040 ft) in the southeast. It is incised from the north by a vast valley, the Cañón del Diablo, formed by the Churún River. The larger western portion of the plateau is partially forested, whereas the eastern part comprises mostly bare rock with only patchy vegetation cover. The mountain hosts a number of extensive cave systems.
The Guayana Region is an administrative region of eastern Venezuela.
Heliamphora hispida is a species of Marsh Pitcher Plant endemic to Cerro Neblina, the southernmost tepui of the Guiana Highlands at the Brazil-Venezuela border.
Heliamphora neblinae is a species of marsh pitcher plant endemic to Cerro de la Neblina, Cerro Aracamuni and Cerro Avispa in Venezuela. It is one of the most variable species in the genus and was once considered to be a variety of H. tatei. It is unclear whether or not there is a consensus regarding its status as a species, with at least a few researchers supporting the taxonomic revision that would elevate both H. tatei var. neblinae and H. tatei f. macdonaldae to full species status.
Heliamphora nutans is a species of marsh pitcher plant native to the border area between Venezuela, Brazil and Guyana, where it grows on several tepuis, including Roraima, Kukenán, Yuruaní, Maringma, and Wei Assipu. Heliamphora nutans was the first Heliamphora to be described and is the best known species.
Heliamphora pulchella is a species of marsh pitcher plant endemic to the Chimanta Massif and surrounding tepuis in Venezuela. It is one of the smallest species and closely related to H. minor.
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 between 300 m (980 ft) and 2,350 m (7,710 ft). 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...".
Upuigma-tepui, also known as El Castillo, is a tepui in Bolívar state, Venezuela. A relatively isolated peak, both it and nearby Angasima-tepui lie just south of the vast Chimantá Massif, from which they are separated by the Río Aparurén valley. Upuigma-tepui is situated entirely within the bounds of Canaima National Park.
Cerro de la Neblina, also known as Serra da Neblina in Brazil and Sierra de la Neblina in Venezuela, is a sandstone massif located in the northern Amazon Basin. It is a tilted, heavily eroded plateau, with a deep canyon in its central portion, drained by the Baria River.
The natural range of the carnivorous plant genus Heliamphora is restricted to the southern Venezuelan states of Amazonas and Bolívar, and to adjacent portions of northern Brazil and western Guyana, an area corresponding to the western part of the Guayana Shield. These plants are largely confined to the summits and foothills of the sandstone table-top mountains of the region, known as tepuis.
Aprada-tepui is a tepui in Bolívar state, Venezuela. It has an elevation of around 2,500 metres (8,200 ft) above sea level. It gives its name to the Aprada Massif, which also includes the smaller Araopán-tepui to the east. A steep, semi-circular ridge connects these two summits. Aprada-tepui lies 22 kilometres (14 mi) northwest of the much larger Chimantá Massif and around 25 km (16 mi) east of the Pemón village of Urimán.
The Chimantá Massif is a highly fragmented complex of tepuis in Bolívar state, Venezuela. The massif comprises around 11 tepuis and has a total summit area of 615 km2 (237 sq mi) and an estimated slope area of 915 km2 (353 sq mi). It is divided in two by the Río Tírica, with the northern section being both larger and higher. The massif is notable for its high species richness and for its varied habitat types. It reaches an elevation of 2,698 metres (8,852 ft) on its highest peak, Murey-tepui. The massif is situated entirely within the bounds of Canaima National Park. It hosts extensive cave systems, including the world's largest known quartzite cave, Cueva Charles Brewer, named after discoverer Charles Brewer-Carías. The processes behind their speleogenesis are the subject of some debate.
Uei-tepui, also known as Wei-tepui, Cerro El Sol or Serra do Sol is a tepui on the border between Brazil and Venezuela. It may be considered the southernmost member of the Eastern Tepuis chain.
Los Testigos, also known as the Aparamán range, is a mountain chain in Bolívar, Venezuela. It consists of four rather small tepuis, forming a bridge between the giant Auyán-tepui to the west and Ptari-tepui to the east. The four major peaks of Los Testigos are : Aparamán-tepui (2,100 m), Murisipán-tepui (2,350 m), Tereke-yurén-tepui (1,900 m), and Kamarkawarai-tepui (2,400 m), the latter three sharing a common slope area. There however remains some confusion in the literature regarding the names of these peaks.
Angasima-tepui, also known as Adanta, Adankasima or Adankachimö, is a tepui in Bolívar state, Venezuela. A relatively isolated peak, both it and nearby Upuigma-tepui lie just south of the vast Chimantá Massif, from which they are separated by the Río Aparurén valley. Amurí-tepui, the closest member of the Chimantá Massif, is only 8 kilometres (5.0 mi) from Angasima-tepui.
Yuruaní-tepui, also known by the Pemón name Iwalkarima, Iwalecalima or Iwarkárima, is a tepui of the Eastern Tepuis chain primarily situated in Venezuela, while part of the eastern ridge stretches into the disputed Guayana Esequiba territory in Guyana. It has an elevation of around 2,400 metres (7,900 ft), the high plateau being located entirely within Venezuela, and a summit area of 4.38 km2 (1.69 sq mi). It lies just east of the much smaller Wadakapiapué-tepui. This Tepui is not located in the Canaima National Park unlike most other Tepuis in the area.
Ptari-tepui, also spelled Pu-tari and sometimes called Cerro Budare or Cerro del Budare, is a tepui in Bolívar state, Venezuela. Lying near the centre of the Sierra de Lema, it has a maximum elevation of around 2,400 metres (7,900 ft) above sea level. Its mostly bare summit plateau has an area of 1.25 km2 (0.48 sq mi). Though generally flat, distinctive erosional rock formations are found on the more dissected eastern edge of the summit.
Karaurín-tepui, also spelled Caraurín, is a tepui of the Eastern Tepuis chain in Bolívar state, Venezuela. It has a maximum elevation of around 2,500 metres (8,200 ft) above sea level. The summit plateau is covered by shrubby vegetation and has an area of 1.88 km2 (0.73 sq mi). The foothills of the tepui are covered in forests. Karaurín-tepui lies just south of the much larger Ilú–Tramen Massif.
Wei-Assipu-tepui, also known as Little Roraima or Roraimita, is a minor tepui of the Eastern Tepuis chain. It lies just off the northeastern flank of Roraima-tepui, directly on the border between Brazil and the disputed Guayana Esequiba territory, claimed by Venezuela but controlled by Guyana, and very close to the tripoint of all three countries. The mountain is known for its extensive cave systems, with one extending for over a kilometre.
