Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30,000-square-kilometre Canaima National Park.
Its 31 km2 plateau summit area consists on all sides of cliffs rising 400 meters (1,300 ft). High altitude rains collect in small lakes and run off the massive cliffs in spectacular waterfalls.
Do a Google/Images search for some really crazy photos of this amazing geological feature.
