Mount Roraima (also known as Roraima Tepui or Cerro Roraima in Spanish,
and Monte Roraima in Portuguese), is the highest of the Pakaraima chain
of tepui plateau in South America.First described by the English
explorer Sir Walter Raleigh in 1596, its 31 km² summit area is defended
by 400m (1,300 ft) tall cliffs on all sides. The mountain includes the
triple border point of Venezuela, Brazil and Guyana.
Mount Roraima lies on the Guiana Shield in the southeastern corner of
Venezuela's 30,000 km² Canaima National Park forming the highest peak of
Guyana's Highland Range. The tabletop mountains of the park are
considered some of the oldest geological formations on Earth, dating
back to some two billion years ago in the Precambrian Era.
The highest point in Guyana and the highest point of the Brazilian state
of Roraima both lie on the plateau, but Venezuela and Brazil have
higher mountains. The triple border point is at 5°12'08N, 60°44'07W, but
the mountain's highest point is Maverick Rock, 2,810 m, at the south
end of the plateau and wholly within Venezuela.
