This 1.8 Billion-Year-Old Summit Is Quietly Being Emptied

Mount Roraima's 1.8-billion-year-old summit is a real lost world, and its ancient quartz crystals are quietly disappearing. Rising 800 meters out of the clouds, this flat-topped sky island is not a peak but a survivor, the last block of a vast sandstone sheet that rain has been carving away for tens of millions of years. Up there, a toad that can't jump rolls off cliffs to escape predators, and carnivorous plants hunt insects and even microbes because the rock offers no nutrients at all. We follow the story from Pemón legend and the first ascent in 1884 to the Arthur Conan Doyle novel it inspired, and to the fragile summit that trekkers visit today. Discover why such a slow-growing, ancient ecosystem needs careful footsteps. #MountRoraima #LostWorld
