A tepui ( //), or tepuy, is a table-top mountain or mesa found in the Guiana Highlands of South America, especially in Venezuela. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana.
Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Neblina, Autana, Auyantepui and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall.
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 400-metre-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 30000 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.
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 , but the mountain's highest point is Maverick Rock, 2810 m, at the south end of the plateau and wholly within Venezuela.
