Mount Roraima
Straddling the borders of three countries and boasting an elevation point of 2,810 meters (9,219 ft), Mount Roraima rises like a primordial table in the southeast corner of Canaima National Park, Venezuela. The ancient plateau is protected by cliffs rising 400 meters (1,300 ft), and though it sits atop Brazil, Venezuela and Guyana, the huge summit is reached from the Venezuelan side almost exclusively due to the sheer cliff faces and differing access restrictions of the three countries.
Mount Roraima was first described in 1596 by English explorer Sir Walter Raleigh, and has been credited as inspiration for Arthur Conan Doyle's The Lost World. The plateau is host to several unique species of flora and fauna, due primarily to the difficult and secluded geological formations which are considered some of the oldest in existence, dating back some two billion years.
