Mount Roraima, Guyana, South America ~ Roraima, soaring more than 8,000 feet into the clouds, is like a prehistoric island in the sky, populated by plants and animals found nowhere else. Almost the entire surface of the summit is bare sandstone, with only sparse vegetation present. It rains almost every day of the year, and most of the nutrients in the soil are washed away by torrents that cascade over the edge, which form some of the highest waterfalls in the world.
Roraima includes the triple border point of Venezuela, Brazil and Guyana. It lies on the Guiana Shield in the southeastern corner of Venezuela’s Canaima National Park, forming the highest peak of Guyana’s Highland Range. The tabletop mountains of the park, called tepuis, are considered some of the oldest geological formations on Earth, dating back to some two billion years ago in the Precambrian.
