Excursion to the deepest cave in the world
• Excursion to the deepest cave in the world
Crow Cave (Kruber cave Krubera Raven) - the deepest cave in the world studied. It is located in an array of Arabica in the Gagra Range in Abkhazia, Georgia. It is part of the system that owns the cave and Arabica. The cave is branched into two branches: Nekuybyshevskuyu and bulk, which, in turn, branches into several smaller branches. The depth of the first - about 1300 meters, the second - about 2196 meters.
The depth of the cave - 2140 (± 9) meters. The previous record for depth of 1710 meters was established in 2001 a Russian-Ukrainian team. In 2004, during three expeditions depth study area each time increased. At this stage the Ukrainian team crossed the mark of 2000 meters below ground level. It was the first time in the history of caving. In October 2005, the new, unexplored parts were found CAVEX team, and explore the cave became deeper. This expedition confirmed that the cave depth is currently 2140 (± 9) meters in depth.
Karst cave subvertical type wells is a series of interconnected stile and galleries. The deepest plumb lines 115, 110 and 152 meters. At a depth of 200 meters of the cave divides into two main branches: Nekuybyshevskaya (for the year 2010 depth 1697 meters) and the main branch (the current depth of 2191 m). Starting from a depth of 1300 meters, the main branch splits into many other branches. At the bottom of a known siphon 8 (located at depths of 1,400 to 2,144 meters). Limestone cave is thicker, the bottom part of the depth of 1600 meters incorporated in the limestone black. Waters Krubera Cave feeds the shortest river in the world - Reprua River.
The cave is open for the first time studied to a depth of 95 m Georgian speleologists in 1960. At the same time it got its first name: Krubera cave, in honor of his father Russian Karst AA Krubera.
The Forgotten Cave secondary investigated Krasnoyarsk cavers in 1968. They used the name of the cave: Siberian.
In 1982-1987 the cave again remembered. This time it was investigated Kiev cavers to a depth of 340 meters there was a third title:. Cave Crow. After the Georgian-Abkhaz war of 1992-1993 the republic was cut off from public access by speleologists. Work resumed in August 1999, when the people of Kiev for one expedition reached a depth of 700 m. In August-September 2000, the same team has reached a depth of 1410 m. In January 2001, the expedition Ukrainian Spelelogicheskoy Association with the participation of Moscow cavers set a world record, reaching 1710 m. this branch is shut up impassable rubble. In August 2003 Cavex team dived fourth siphon into the side branch and stopped at a depth of 1680 m with a free extension. In July 2004, the same team in the same branch has set a new world record -. 1775 m in August of the same year UCA expedition explored another branch. Once again the world record -. 1840 m Two months later, UCA has organized a new expedition in October 2004. October 19 for the first time in the history of caving overcome 2-kilometer line - 2080 m.
For decades, the palm in the rank of the deepest caves belonged to the French caves Pierre Saint Martin and Jean Bernard, outgoing into the earth for 1,600-plus yards. However, the event took place in 1960, which gradually become deprived of their leadership. Cavers who worked in Abkhazia Arabica array, found no one previously known cave. In that year, they were able to go down by only 150 meters, which, of course, not only did not give the right to name a new cave the deepest, but even classify it to the deepest caves in the world. The only thing that could make cavers, so give it a new name of the cave - a cave Krubera in honor of the founder of the Russian and Soviet karstology (the science of the effects of water on the rocks) Alexander Krubera.
Then a long history began resembling auction that occurs with any cave after opening: every next Speleological expedition announced the release of the new depth - 210, 340, 710 meters ... It is worth noting that just at the level of 340 meters of the cave Krubera received new name - Crow. In the future, both informal names joined together in a single official - Krubera Raven.
The deepest point is available for the visit of the two other entrances to the cave system Arabika: cave Kuybyshev and Genrihovoy Abyss, which are located further on the mountainside. The cave entrance is from another representative system Berchilskoy cave is 100 meters higher than the cave Crow. The total depth of the bunch is about 2240.
