Mount Roraima (Spanish: Monte Roraima; Tepuy Roraima Portuguese: Monte Roraima [ˈmõtʃi ʁoˈɾajmɐ], and Cerro Roraima;) is the highest of the Pakaraima chain of tepuis (table-top mountain) or plateaux in South America.:156 First described to Europeans by the English explorer Sir Walter Raleigh during his 1595 expedition, its 31-square-kilometre (12-square-mile) summit area:156 is bounded on all sides by cliffs rising 400 metres (1,300 ft). The mountain also serves as the tripoint of Venezuela, Guyana and Brazil.:156
Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30,000-square-kilometre (12,000-square-mile) Canaima National Park forming the highest peak of Guyana's Highland Range.
The highest point in Guyana and the highest point of the Brazilian state of Roraima lie on the plateau, but Venezuela and Brazil have higher mountains elsewhere. The triple border point is at , but the mountain's highest point is Laberintos del Norte.
85% of this tepui is in Venezuelan territory (Bolívar state), with 10% in the territory of Guyana (Cuyuni-Mazaruni, Zone also claimed by Venezuela), and 5% belonging to the state of Roraima in Brazil.
Flora and fauna
Many of the species found on Roraima are unique to the tepui plateaus with two local endemic plants found on Roraima summit. Plants such as pitcher plants (Heliamphora), Campanula (a bellflower), and the rare Rapatea heather are commonly found on the escarpment and summit.:156–157 It rains almost every day of the year. Almost the entire surface of the summit is bare sandstone, with only a few bushes (Bonnetia roraimae) and algae present.:517:464:63 Low scanty and bristling vegetation is also found in the small, sandy marshes that intersperse the rocky summit.:517 Most of the nutrients that are present in the soil are washed away by torrents that cascade over the edge, forming some of the highest waterfalls in the world.
There are multiple examples of unique fauna atop Mount Roraima. Oreophrynella quelchii, commonly called the Roraima Bush Toad, is a diurnal toad usually found on open rock surfaces and shrubland. It is a species of toad in the family Bufonidae and breeds by direct development. The species is currently listed as vulnerable and there is a need for increased education among tourists to make them aware of the importance of not handling these animals in the wild. Close population monitoring is also required, particularly since this species is known only from a single location. The species is protected in Monumento Natural Los Tepuyes in Venezuela, and Parque National Monte Roraima in Brazil.
Since long before the arrival of European explorers, the mountain has held a special significance for the indigenous people of the region, and it is central to many of their myths and legends. The Pemon and Kapon natives of the Gran Sabana see Mount Roraima as the stump of a mighty tree that once held all the fruits and tuberous vegetables in the world. Felled by Makunaima, their mythical trickster, the tree crashed to the ground, unleashing a terrible flood.Roroi in the Pemon language means blue-green and ma means great. It is also said to have inspired Paradise Falls from the Pixar film Up.
Although the steep sides of the plateau make it difficult to access, it was the first recorded major tepui to be climbed: Sir Everard im Thurn walked up a forested ramp on 18 December 1884 to scale the plateau, the route also used by the Clementis in their climb of 15 January 1916.:463 It is currently one of the most important mountain trekking routes in Venezuela, visited by people from many places in the world.
The only non-technical route to the top is the Paraitepui route from Venezuela; any other approach will involve climbing gear. Mount Roraima has been climbed on a few occasions from the Guyana and Brazil sides, but as the mountain is entirely bordered on both these sides by enormous sheer cliffs that include high overhanging (negative-inclination) stretches, these are extremely difficult and technical rock climbing routes. Such climbs would also require difficult authorizations for entering restricted-access national parks in the respective countries.
The ascent of the northern 'Prow' by British climbers Mo Anthoine, Joe Brown, Hamish MacInnes, and Don Whillans in 1973 was filmed for a TV documentary, and recorded in a book by MacInnes  The 2013 Austrian documentary Jäger des Augenblicks - Ein Abenteuer am Mount Roraima (Moment Hunters - An Adventure on Mount Roraima) shows rock climbers Kurt Albert, Holger Heuber, and Stefan Glowacz climbing to the top of Mount Roraima from the Guyana side. Similarly, in 2010 Brazilian climbers Eliseu Frechou, Fernando Leal and Márcio Bruno opened a new route on the Guyanese side, climbing to the top in 12 days of a very difficult vertical wall climb. They called the new route Guerra de Luz e Trevas (Portuguese for "War of Light and Darkness") and classed it as 6° VIIa A3 J4. A 28-minute Vimeo video called Dias de Tempestade (Days of Storm) is available documenting their climb (English subtitles, audio in Portuguese).
In popular culture
A report by the noted South American researcher Robert Schomburgk inspired the Scottish author Arthur Conan Doyle to write his novel The Lost World about the discovery of a living prehistoric world full of dinosaurs and other primordial creatures.

Lord Aberdare said that Mr. Perkins, who accompanied Mr. im Thurn in the ascent of the mountain, had fared little better, inasmuch as he also had been severely attacked by fever since his return, and though present that evening, was still too weak to read his notes.

For all around wore rocks and pinnacles of rocks of seemingly impossibly fantastic forms, standing in apparently impossibly fantastic ways—nay, placed one on or next to the other in positions seeming to defy every law of gravity—rocks in groups, rocks standing singly, rocks in terraces, rocks as columns, rocks as walls and rooks as pyramids, rocks ridiculous at every point with countless apparent caricatures of the faces and forms of men and animals, apparent caricatures of umbrellas, tortoises, churches, cannons, and of innumerable other most incongruous and unexpected objects.

The summit is covered with enormous black boulders, weathered into the weirdest and most fantastic shapes. We were in the middle of an amphitheatre, encircled by what one might almost call waves of stone. It would be unsafe to explore this rugged plateau without white paint to mark one's way, for one would be very soon lost in the labyrinth of extraordinary rocks. There is no vegetation on Roraima save a few damp-sodden bushes (Bonnetia Roraimœ), and fire sufficient for cooking can be raised only by an Indian squatting beside it and blowing all the time.

In general the interior plateau looks flat and monotonous. Appearance is deceptive, for there are actually very few places where walking is not difficult, and these follow the joint system of the sandstone. For the most part, tumbled masses of rock, rifts, and gorges and whole acres of ten-foot mushrooms and loaves of bread formed in stone offer a maze in which one may wander long before finding better ground; while gullies many yards in depth and breadth, meandering undecidedly, force detours of sometimes half a mile.
