Roraima

Roraima, an isolated, table-topped sand-stone mountain, near the west border of British Guiana. First sloping gradually upwards 5000 feet above sea-level (2500 above the plain on which it stands), it next shoots up 2000 feet more in a perpendicular stupendous cliff, over which drop numerous waterfalls. It was first scaled by E. F. im Thurn on 18th December 1884.
