Sarisarinama
From Wikipedia, the free encyclopedia
The Sarisariñama tepui is a mountain in the Jaua-Sarisariñama National Park at the far south-west of Bolívar State, Venezuela, near the border with Brazil. Latitude/longitude 4° 33' N, 64° 14' W
This mountain is one of the most remote in the country, with the closest road being hundreds of miles away. Access is restricted to scientific researchers only.
The most distinctive feature of this 2,300 meter high tepui are its fascinating, nearly perfectly, circular sink holes that are still a challenging mystery to geologists and biologists. The holes have a diameter of 350 meters and go down from the flat top of the mountain straight down for 350 meters (over 1,000 feet). The vertical walls have managed to create an isolated ecosystem at the bottom with some species of plants and animals not found anywhere else in the world. These sink holes were first seen and explored in 1974.
