Mount Roraima Spanish: Monte Roraima; Tepuy Roraima Portagues: is the highest of the Pakarima chain of (table-top mountain) or plateau in South America. First described to Europeans by the English explorer Sir Walter Raliegh during his 1595 expedition, its 31-square-kilometer (12-square-mile) summit area is bounded on all sides by cliffs rising 400 meters (1,300 ft). The mountain also serves as the tripoint of Venezuela, Guyana, and Brazil Raleigh learned about it from indigenous peoples, who lived there before the arrival of Europeans in the 1500–the 1600s.
Mount Roraima lies on Guyana 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.
