Mount Roraima is over 2 billion years old, predating animals, trees, and dinosaurs. Its sheer 400-meter cliffs isolate an ecosystem found nowhere else on Earth

    It looks like somebody just dropped a paving stone in dry ice.

    I have seen this perspective in every picture of this place. however I have never seen a single picture or description of what’s actually up there. I guess I need to go proactively find out… to Wikipedia!

    I’m back!

    Due to the late exploration of this part of South America and the discovery of new species every year, the flora and fauna here are largely unknown.[9] The currently identified species are strongly endemic, especially the fauna, which also puts them at a high risk of extinction.[12]

    The vegetation on the plateau is still largely unknown and consists mainly of bare rocks, forests of trees and epiphytes, and wet and dry savannas in the form of swamps.[9] It is marked by numerous endemic species, especially carnivorous plants that capture insects, living in sandstone and leaching soils which lack the nitrates necessary for their development.[21][14][12] There are fewer species in the vicinity of streams and ravines, and the trees are 8–15 m (26–49 ft) tall and have hard leaves that can adapt to harsh environmental conditions.[9] The exposed rocks are occupied by lichens, algae and cyanobacteria.[16]

      Thank you! I thought I was going to have to look it up myself.

      Was not expecting a swamp up there lol. That caught me off guard.

      Forests: okay. bare rocks: expected. A swamp? Was not picturing that lol

        I would guess a helicopter, but I’m sure you could climb it.

          i am not a scientist, but would love to climb it. there is an establishment treck to the top. but those cliff sides just look like an amazing expedition. maybe one day, with more training on big walls and quite some money…

    To be clear, the rocks that the mountain is made of are reasonably old (oldest on Earth is closer to 4.0 billion years, but anything >500 million is fairly rare), but the landform of a mountain is a combination of uplift and erosion, which is fairly young. The only source for the age of erosion I could find (didn’t search hard) mentioned the glaciation of the Pleistocene, which seems reasonable.

    Every few years I am reminded that it exists, and become briefly obsessed. I want to write an entire fictional setting based on Roraima’s geological and ecological oddity

      Was this the place where that young adult apocalypse book was based on? I think it was called the giver or something.

        Never heard of it, but I can’t find anything that connects it to Roraima.

            That image is from the movie. I don’t recall there ever being much mention of the location or geography in the book.

    The Venezuelan tepuis are one of the most fascinating places on earth! I discovered them from a National Geographic story when I was a kid. The world’s tallest waterfall tumbles off one of these mesas. It’s too bad my country (US) has ruined any chance for me to ever safely visit them in person.

    If you look real close at the left side of the plateau you can see an old man, a kid and a dog.

        No reference. OP must have really good eyes or gotten really lucky zooming. The guy appears to have recently lost his wife.
