Mount Roraima (Hike to the top of the “Lost World”), South America

Mount Roraima is the highest of the Pakaraima chain of tepui plateaus in South America. First described by the English explorer Sir Walter Raleigh during his 1595 expedition, its 31-square-kilometre (12-square-mile) summit area 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. 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 5°12′08″N 60°44′07″W, but the mountain's highest point is Laberintos del Norte. 

 

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, Campanula , and the rare Rapatea heather are commonly found on the escarpment and summit. It rains almost every day of the year. Almost the entire surface of the summit is bare sandstone, with only a few bushes and algae present. Low scanty and bristling vegetation is also found in the small, sandy marshes that intersperse the rocky summit. 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 Nacional Monte Roraima in Brazil

 

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 in December 1884 to scale the plateau. This is the same route hikers take today. 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.

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.In Brazil the Monte Roraima National Park lies within the Raposa Serra do Sol Indigenous Territory, and is not open to the public without permission.

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.
