Mount Roraima (Spanish: Monte Roraima; Tepuy Roraima; Cerro Roraima; Portuguese: Monte Roraima) is the highest of the Pacaraima chain of tepuis (table-top mountain) or plateaux in South America. It is located at the junction of Brazil, Guyana and Venezuela. A characteristic large flat-topped mountain surrounded by cliffs 400–1,000 m (1,300–3,300 ft) high. The highest point of Mount Roraima is located on the southern edge of the cliff at an elevation of 2,810 m (9,220 ft) in Venezuela, and another protrusion at an elevation of 2,772 m (9,094 ft) at the junction of the three countries in the north of the plateau is the highest point in Guyana. The name Mount Roraima came from the native Pemon people. Roroi in the Pemon language means "blue-green", and ma means "great". Leaching caused by intense rainfall has shaped the peculiar topography of the summit, and the geographical isolation of Mount Roraima has made it home to much endemic flora and fauna. Western exploration of Mount Roraima did not begin until the 19th century, when it was first climbed by a British expedition in 1884. Yet despite subsequent expeditions, its flora and geology remain largely unknown. The privileged setting and relatively easy access and climbing conditions on the south side of the cliffs make Mount Roraima a popular destination for hikers.
