We've Been Descending This Cave for 60 Years and Still Haven't Found the Bottom

On a remote mountain in the Western Caucasus, there is a hole in the ground that drops more than two kilometres straight down into darkness. It has taken explorers over sixty years to reach the bottom — and some of them never came back up. This is Krubera, and its neighbour Veryovkina: the two deepest known caves on Earth, and the furthest down a human being has ever physically descended into the planet. Reaching the lowest point takes weeks underground, freezing water, vertical shafts, and flooded passages that can kill in seconds. We descend the whole way down — through the camps, the sumps, and the cold — to the deepest living animal ever found, and to the unsettling truth at the very bottom: the cave doesn't end where the map does. Krubera Cave (also called Voronya, or Crow's Cave) and Veryovkina Cave both lie in the Arabika Massif of the Western Caucasus, in Abkhazia. They are the only two known caves on Earth deeper than 2,000 metres, with surveyed depths around 2,200 metres. This documentary covers the geology of the limestone massif, the decades-long exploration history, the extreme conditions of deep caving, and the unique eyeless, pigmentless life discovered near the bottom — including Plutomurus ortobalaganensis, the deepest terrestrial animal ever recorded. #DarkAtlas #KruberaCave #DeepestCave #Caving #Documentary
