National Geographic journalist Mark Synott, went down to the deepest caves in the world, located in Uzbekistan, in Boysun Mountains. He was a part of an international team that included Russian, Italian and Israeli researchers. The cave is called Dark Star in honor of a fantastic movie of 1974, directed by John Carpenter. Also, it is called “Underground Everest”.
The cave is poorly studied, so the purpose of cavers is to collect as much data as possible for research. According to preliminary calculations, the bottom of the cave is at a depth of 2 650 meters, compared with the cave Krubera in Georgia, at 500 meters deeper.
Mark Synnott finished writing an article, which described in detail the history and feelings while he was in the cave. The article can be found on the National Geographic web site
