Mount Roraima is generally known as Tepuy Roraima and Cerro Roraima; is the highest of the Pakaraima chain of Tepui plateau in South America. Firstly identified by the English explorer Sir Walter Raleigh in 1596, its 31 km to summit area is shielded on all sides by tall cliffs rising 400 metres (1, 300 ft). The mountain contains the triple boundary point of Venezuela, Brazil and Guyana. Mount Roraima is situated on the Guiana Shield in the southeastern corner of Venezuela's 30, 000 square kilometres (12, 000 sq mi) Canaima National Park forming the highest possible peak of Guyana's Highland Range. The tabletop mountains of the park are thought to be the one of the oldest geological structures on Earth, dating back to certain two billion years ago in the Precambrian.
The peak point in Guyana and the peak point of the Brazilian state of Roraima lie on the plateau; however Venezuela and Brazil have higher mountains somewhere else.
