Mount Roraima

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 mountain's highest point is Maverick Rock or Maverick Stone, at the southern end of the plateau and wholly within Venezuela.
