Mount Roraima lies on the Guiana Shield in the southeastern corner of Venezuela’s 30,000-square-kilometre 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.
