- Mount Roraima (mountain, South America) giant flat-topped mountain, or mesa, in the Pakaraima Mountains of the Guiana Highlands , at the point where the boundaries of Brazil, Venezuela, and Guyana meet
- About 9 miles (14 km) long and 9,094 feet (2,772 metres) high, it is the source of many rivers of Guyana, and of the Amazon and Orinoco
- Mount Roraima is a pretty remarkable place. It is a tabletop mountain with sheer 400-metre high cliffs on all sides
- There is only one ‘easy’ way up, on a natural staircase-like ramp on the Venezuelan side – to get up any other way takes and experienced rock climber
- On the top of the mountain it rains almost every day, washing away most of the nutrients for plants to grow and creating a unique landscape on the bare sandstone surface
- This also creates some of the highest waterfalls in the world over the sides (Angel falls is located on a similar tabletop mountain some 130 miles away)
- Though there are only a few marshes on the mountain where vegetation can grow properly, these contain many species unique to the mountain, including a species of carnivorous pitcher plant
- The mountain marks the border between Venezuela, Brazil and Guyana, although more than three quarters of the mountain is in Venezuelan territory
- It is the highest mountain in Guyana, but Venezuela and Brazil have higher mountains. The triple border point on the summit is at 5°12'08N, 60°44'07W
- Roraima lies on the Guiana Shield in the southeastern corner of Venezuela's 30,000 km² Canaima National Park, which is roughly located in the Gran Sabana region
