Veryovkina Cave (Russian: Пещера Верёвкина, Georgian: ვერიოვკინის მღვიმე) is 2,212 meters (7,257 ft) deep and is the deepest-known cave on Earth.[1][2] Its entrance is situated 2,309 meters (7,575 ft) above sea level[3] in Abkhazia, Georgia. The entrance of the cave has a cross section of 3 m × 4 m (9.8 ft × 13.1 ft), and is located in the Arabika Massif, Gagra Mountain Range of the West Caucasus, on the pass between the Krepost[4] and Zont[5] mountains, closer to the slopes of Mt. Krepost. The depth of the entrance shaft is 32 meters (105 ft).

Naming[edit]

In 1968, the cave was assigned the name S-115 which was later replaced by P1-7, and in 1986 it was renamed after Alexander Veryovkin. Caver and cave diver Alexander Veryovkin died in 1983 while exploring a siphon in the cave Su-Akan, located in the Sary-Tala massif, now Kabardino-Balkaria, Russia.

Discovery[edit]

  • The entrance is located in the Gagra district of Abkhazia, Georgia.
  • 1968 - the cave was discovered by cavers from Krasnoyarsk. They reached a depth of 115 meters (377 ft) and marked it on the map as S-115.
  • 1982 - the cave was discovered for the second time by the expedition of the "Perovo" speleoclub from Moscow. It was marked as P1-7.
  • 1983 - 1986 cavers from the same team continued exploration and reached the depth of 440 m (1,440 ft).
  • 1986 - 2000 work in the cave did not take place.

Explorations after 2000[edit]

  • From 2000 to 2015 the speleoclub "Perovo" and its team "Perovo-speleo" continued research at the cave bottom. Despite all the efforts the cave depth remained at 440 m (1,440 ft).
  • August 2015 - cavers from the speleoclub "Perovo" finally discovered a new shaft, its depth was later determined to be 156 m (512 ft). This discovery opened the way to a series of later discoveries.
  • June 2016 - the expedition of the team "Perovo-speleo" took place, to a depth of 630 m (2,070 ft).
  • August 2016 - a joint expedition of the "Perovo-speleo" team and the "Perovo" speleoclub reached the depth of 1,010 m (3,310 ft).
  • October 2016 - the expedition of the team "Perovo-speleo" deepened the cave to 1,350 m (4,430 ft).
  • February 2017 - the expedition of the "Perovo-speleo" team reached the depth of 1,832 m (6,010 ft) The cave advanced to the second deepest in the world, after Krubera (Voronya) cave.
  • Beginning of August 2017 - the speleoclub "Perovo" explored the cave to the depth of 2,151 m (7,057 ft). An ancient collector of the karst aquifer system with extensive horizontal tunnels, not typical for the Arabica massif, was discovered. Veryovkina became the second super deep cave (over 2 km (1.2 mi)) and the deepest accessible without diving equipment.
  • Second half of August 2017 - the "Perovo-speleo" team reached the depth of 2,204 m (7,231 ft), thus setting a new world depth record. A huge system of more than 6,000 m (20,000 ft) of subhorizontal passages below the −2,100 m (−6,900 ft) was discovered and surveyed.
  • March 2018 - another expedition of the same team added more than a kilometer of tunnels to the cave map. They also measured the depth of The last Nemo station terminal siphon lake. It was 8.5 m (28 ft) and so the total cave depth reached 2,212 meters (7,257 ft)[1].
