41-593: The range extends from west to east for over 800 kilometres (500 mi). Its highest peak is Mount Roraima at 2,810 metres (9,220 ft) above sea level, a tepui surrounded by cliffs 300 metres (980 ft) high. It is geologically part of the Guayana Shield and biogeographically part of the Guayana Highlands .The mountains form the divide between the Orinoco Valley to the north and

82-590: A Catholic majority population, and left behind their ancestral language and belief, still, many Pemon people, known as "Chamanes" still practice the ancestral religion, mostly for healthcare. Pemon (in Spanish : Pemón), is a Cariban language spoken mainly in Venezuela , specifically in the Gran Sabana region of Bolívar State . According to the 2001 census there were 15,094 Pemon speakers in Venezuela . It

123-519: A Royal Geographical Society-funded expedition to explore British Guiana (1835–1839). In 1840, the British government commissioned him to establish the boundaries between British Guiana and Venezuela. When he returned to the area in 1844 to study the local flora, he reported that the peak seemed inaccessible due to its towering cliffs. In 1864, German naturalist and botanist Carl Ferdinand Appun and British geologist Charles Barrington Brown arrived at

164-501: A challenge, however the relative isolation of these flat-topped mountains produces an array of endemic flora with a "great potential for high species diversity". The Rapateaceae family is one of the most commonly represented of flowering plants amid the tepui plateaus. Logging and mining interests pose a threat to the biodiversity of the Pacaraimas. The 116,748 hectares (288,490 acres) Monte Roraima National Park protects part of

205-409: A large amount of quartz deposits, 98% are silica particles, forming white or pink crystals several centimeters long. These rocks sit on a granite and gneiss base and were originally covered by layers of Mesozoic clay, conglomerate, and diorite , but have been exposed by erosion and by orogeny over the past 180 million years, eroded by precipitation to form strange shapes. The soil of

246-491: A natural boulder. The base of the cliff is surrounded by steep slopes to the south and east, and the north and west sides form river valleys leading to the summit. The top of Mount Roraima has a length of more than 10 km (6.2 mi), a maximum width of 5 km (3.1 mi), an area of about 33–50 km (13–19 sq mi), an elevation of more than 2,200 m (7,200 ft), and an average elevation of 2,600–2,700 m (8,500–8,900 ft). The plateau

287-472: Is a flat-topped mountain, typical of the Guyana Shield , with an elevation of about 1,200 m (3,900 ft) in the southeast and only about 600 m (2,000 ft) in the northwest. The south, southeast, east, northeast and northwest faces are all formed by straight cliffs up to about 1,000 m (3,300 ft) high. At the southern end of the mountain, part of the cliff has collapsed, forming

328-453: Is a pseudo- karst surface etched by heavy rainfall. The highest point is 2,810 m (9,219 ft) above sea level, located at the southern end of the plateau and the highest point in the state of Bolívar , 8.25 km (5.13 mi) north of the summit is another high point with an elevation of 2,772 m (9,100 ft), which is the highest point in Guyana. In the northern part of

369-440: Is chosen by almost all hikers, the only difficulty is that some streams and small waterfalls may become difficult to pass under heavy rain. However, the length of the trail requires climbers to spend one night at the base camp at the foot of the cliff at an elevation of about 2,000 meters, and another night at the summit, taking several days to explore the plateau and two days to descend. The best time to climb Mount Roraima

410-466: Is divided into three principal dialects, which are; Arekuna, Kamarakoto, and Taurepang. The Pemon have a very rich mythic tradition which is merged into their present Christian faiths. Pemon mythology includes gods residing in the grassland area's table-top mountains called tepui . The mountains are off-limits to the living, as they are also home to ancestor spirits called mawari . The first non-native person to seriously study Pemon myths and language

451-411: Is in the dry season, however, when the sun is very strong and the temperature is high, it can make the road to the mountain difficult. Pemon The Pemon or Pemón (Pemong) are indigenous people living in areas of Venezuela , Brazil , and Guyana . The Pemon people are divided into many dialects and traditions, which are Arekuna , Kamarakoto , and Taurepang. The Pemon are part of

492-597: The Amazon Basin to the south. They also serve as a natural boundary in the east–west direction, where they extend 800 kilometres (500 mi) to form a border marker between Brazil and southeastern Venezuela and between Brazil and west central Guyana. The Pacaraimas are a sandstone plateau underlain by a horizonal precambrian marine strata that arose in post-cretaceous time. Erosion of the sandstone (the Roraima Supergroup) results in dramatic escarpments,

533-462: The Orectanthe sceptrum , Sauvagesia imthurnii , Celiantha imthurniana , Roraima marsh pitchers ( Heliamphora nutans ), Gran Sabana sundew ( Drosera felix ), Roraima bladderworts ( Utricularia quelchii ), Roraima "azaleas" ( Bejaria imthurnii ) and many more. The fauna at the foot of the mountain are composed of a variety of mammals, and this huge diversity is particularly prominent in

574-662: 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 400–1,000 m (1,300–3,300 ft) high. The highest point of Mount Roraima is located on the southern edge of the cliff at an elevation of 2,810 m (9,220 ft) in Venezuela, and another protrusion at an elevation of 2,772 m (9,094 ft) at

615-404: The "tree of life". These brothers transformed people, animals, and other things into rock formations, thus giving them special mythological origins. 5°00′N 61°00′W  /  5.000°N 61.000°W  / 5.000; -61.000 Mount Roraima Mount Roraima ( Spanish : Monte Roraima; Tepuy Roraima; Cerro Roraima ; Portuguese : Monte Roraima ) is the highest of

656-543: The "tree of the world", which he cuts down and the resulting stump becomes Mount Roraima . The falling of the tree caused a great cataclysm, with floods and fire, and humans were recreated by Makunaíma. Makunaíma also turned people and animals into stone that are a part of Pemon description of the natural world. Missionary work among Amerindians has impacted Pemon belief; and Jechikrai is the Pemon adaptation of Jesus Christ. In 1999, Wolfgang Kraker von Schwarzenfeld arranged

697-462: 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 helped fund community projects, and ecotourism opportunities are also being developed. In Venezuela, Pemon live in the Gran Sabana grassland plateau dotted with tabletop mountains where the Angel Falls ,

738-479: The 19th century, when it was first climbed by a British expedition in 1884. Yet despite subsequent expeditions, its flora and geology remain largely unknown. The privileged setting and relatively easy access and climbing conditions on the south side of the cliffs make Mount Roraima a popular destination for hikers. Mount Roraima is located in the northern part of South America, the Pacarema Mountains in

779-540: The Amazon rainforest, such as sloths , anteaters , tapirs , armadillos , capybaras , opossums , agouti , weasels , raccoons , deer , cougars , and primates such as howler monkeys and capuchins . There are hundreds of species of birds, the most common of which include falcons , parrots , and owls . Some hummingbirds are endemic to the region. Due to low mobility relative to other species, reptiles and amphibians show large differences between individuals found at

820-487: The Pacaraimas. The Pacaraimas are mostly forested, with occasional savannas especially at the base of Roraima and on the Brazilian side of the range. The savannas are made up of grasses and the occasional Curatella americana trees below 6500 ft. These areas are prone to fire, either man-made for agriculture or cattle ranching or during times of drought. Difficulty in breaching the steep slopes has made data collection

861-538: The Royal Geographical Society that culminated on December 18, 1884, when the team met local people known as the Pemón who could have climbed to the top of Mount Roraima prior to their expedition. The explorers still believed the top of the cliff to be previously unknown to humans. Soon, many expeditions made up of botanists, zoologists and geologists made multiple expeditions to Mount Roraima to study

902-578: The Venezuelan border. The Pemon language and people have been extremely affected by tourism and historical events like the establishment of the Canaima camp founded by the Boulton family nearby the Canaima town, where the demographic concentration of Pemon people is established. Many Pemon people work in hotels and tourism. This deeply affected the tradition of the Pemon people, as they turned out to be

943-446: The bottom and top of Mount Roraima. While species inhabiting forests at the foot of the plateau are common, such as green iguanas , pit vipers , coral snakes and pythons , those found at the top are even rarer. Cave fauna consists of many species of bats , grasshoppers , spiders and centipedes , but this fragile subterranean ecosystem is being disturbed by surface hikers, organic matter produced by tourists, and explorers over

984-560: The cliff at the foot of the mountain is an evergreen rainforest composed of trees 25–45 m (82–150 ft) high, and some can reach 60 m (200 ft). Vegetation is dominated by Arecaceae and Astragalus . The soils on the cliffs are more sandy, the climate is cooler, and the vegetation consists of bromeliads very similar to the Andes. The vegetation on the plateau is still largely unknown and consists mainly of bare rocks, forests of trees and epiphytes , and wet and dry savannas in

1025-433: The crevices of the rock and flowed out in the form of waterfalls on the mountainside, creating many streams at the foot of the mountain. Due to the late exploration of this part of South America and the discovery of new species every year, the flora and fauna here are largely unknown. The currently identified species are strongly endemic, especially the fauna, which also puts them at a high risk of extinction. The bottom of

1066-508: The eastern part of the Guyana Plateau, Brazil in the east accounting for 5% of its area, Guyana in the north accounting for 10%, and Venezuela in the south and west accounting for 85%. Access to Mount Roraima from the Venezuelan side is close to the road and relatively easy; however, for both Brazil and Guyana the area is completely isolated and can only be reached by a few days of forest hikes or small local airstrip. Mount Roraima

1107-512: The form of swamps. It is marked by numerous endemic species, especially carnivorous plants that capture insects, living in sandstone and leaching soils which lack the nitrates necessary for their development. There are fewer species in the vicinity of streams and ravines, and the trees are 8–15 m (26–49 ft) tall and have hard leaves that can adapt to harsh environmental conditions. The exposed rocks are occupied by lichens , algae and cyanobacteria . Endemic flora includes plants like

1148-544: The individual remnants of which are called tepuis . Mount Roraima , Mount Ayanganna and Mount Wokomung are some of the more well-known examples. Numerous rivers originate in these mountains and on their way down they plunge spectacularly to form some picturesque waterfalls. A beautiful example of this is the Kaieteur Falls in Guyana. The headwaters of the Mazaruni River and Ireng River are sourced in

1189-473: 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

1230-630: 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

1271-589: The largest quartz cave in the world, discovered by the Oxford University Cave Club and the Venezuelan Speleological Society. These caves are formed by the infiltration of surface water, so the water level inside them depends largely on the precipitation on the surface of the plateau: prolonged drought can dry up waterways, and dry caves can also become underground rivers. The water that poured into it rushed into

1312-518: The mostly unknown flora and fauna and special geological conditions of the area. Mount Roraima and Mount Aoyan are the only flat-topped mountains in the Canaima National Park that can be climbed by hikers, with a monthly quota of 200 people. Its ascent takes three to five days in total, the summit route is on a natural slope on the southwestern cliffs of Mount Roraima, it does not require any special equipment or training, so it

1353-459: The plateau is the landmark of the border between Brazil, Venezuela and Guyana, with an elevation of 2,734 m (8,970 ft). Due to its height and proximity to the equator, Mount Roraima has a constant average annual temperature between 20–22 °C (68–72 °F) and annual rainfall of more than 1,500 mm (59 in), with 1,800–3,000 mm (71–120 in) in parts of the rainy season from April to November. The climatic conditions at

1394-638: The range in Roraima , Brazil. The mountains are a traditional home to Patamona and Macushi people. The Macushi village of Tipuru is considered the oldest village in the South Pakaraima Mountains. It has the oldest church and school in the region. Landmarks are of special significance to indigenous people, and are intertwined with oral histories and culture. According to Macushi cosmology, mountains and other landforms were created by mythical creator brothers when they cut down Wayaka ,

1435-470: The sandstone matrix is highly acidic, poor in nutrients, and very fine. Intense rainfall prevents the fixation of nutrients and particles, thereby preventing the formation of hilltop vegetation and soil. The numerous caves and rifts in the interior of the plateau make Mount Roraima exhibit a pseudo- karst structure, and these caves form a network over 15 km (9.3 mi) long, with a total height difference of 73.21 m (240.2 ft). It contains

1476-461: The southeastern tip of Mount Roraima for observation and proposed to go up the mountain by hot air balloon. Although its vertical cliffs make access very difficult, Mount Roraima was the first large mesa to be climbed in the Guyana Plateau. Henry Whiteley , who studied the birds of the area, observed that the summit could be reached from the south with the help of ropes and ladders. Everard im Thurn and Harry Perkins led an expedition sponsored by

1517-403: The top of the mountain differ significantly from its base, the high cloudiness in the region is associated with the prevailing northeasterly and southeasterly winds, and the relative humidity of the air remains between 75% and 85%. Mount Roraima is composed of Proterozoic age sandstone formed about 1.7 to 2 billion years ago, and hence amongst the oldest rocks on Earth. It contains

1558-658: The two subspecies of sparrow, the Zonotrichia capensis roraimae and the Zonotrichia capensis macconelli . One of the most well known endemic species is the Roraima toad ( Oreophrynella quelchii ). European discovery was in 1595, during a Spanish and British race to colonize this part of South America. The English poet, army officer and explorer Walter Raleigh described it as an immeasurable "crystal mountain" gushing countless waterfalls. The first expedition to Mount Roraima took place in 1838, when German scientist and explorer Robert Hermann Schomburgk observed it during

1599-538: The world's highest waterfall, plunges from Auyantepui in Canaima National Park . In Brazil, Pemon live among other indigenous people near the borders of Venezuela and Guyana in villages within the Terras Indígenas São Marcos and Raposa Serra do Sol. There are 792 Pemon according to a 2014 estimate. The Makuxi , who are also Pemon speakers, are found in Brazil and Guyana in areas close to

1640-520: The years. Pollutants such as fuel are washed into the ground by rainwater, which leads to the proliferation of microorganisms and causes ecological imbalance. Endemic species include rodents such as the Roraima climbing mouse ( Rhipidomys macconnelli roraimae ) or the rarer Roraima mouse ( Podoxymys roraimae ), as well as many birds such as the Greater flowerpiercer ( Diglossa major ) or

1681-582: Was the German ethnologist Theodor Koch-Grunberg , who visited Roraima in 1912. Important myths describe the origins of the sun and moon, the creation of the tepui mountains – which dramatically rise from the savannahs of the Gran Sabana — and the activities of the creator hero Makunaíma. Makunaíma is described as an individual or a group of brothers, sons of the sun Wei and a woman made of clay. He goes searching for his father who had been captive of malevolent spirits. After finding his father, Makunaíma finds
