Close Krubera (Voronja) Cave: the first 2000m+ cave on Earth

August 2004 expedition news

Arabika is an outstanding alpine karst massif in the Western Caucasus, were many deep cave explorations have been made since 1980, including Krubera-Voronja (-1710m) and the nearby Arabikskaja system (Kujbyshevskaja-Genrikhova Bezdna; -1110 m) in the Ortobalagan Valley.

Other prominent caves in various sectors of the massif are Iljukhina system (-1240 m), Dzou Cave (-1080 m), Moskovskaja Cave (-970 m) and the Sarma Cave (-1530m). The hydrogeological potential of Arabika had been proven to be over 2300m by dye tracing tests conducted in 1984-85. The exploration of the Krubera cave to -1710m by the Ukrainian Speleological Association had established a world depth record in the beginning of 2001.

Besides the core of the Ukrainian cavers, the Arabika expedition in August 2004 was composed of explorers from Moldova, Spain, France, the United States, Britain, Russia and Abkhazia.

In the summer of 2003, the expedition of the Cavex team and the Kiev Speleo-Club found a new branch behind a siphon at -1440m in a small passage that diverges from the main route to the -1710 bottom. This July, immediately before the Ukr.S.A. expedition, the expedition of Moscow cavers briefly explored the post-siphon section and ended at another siphon at the depth which they estimated to be 1830m. This figure had been claimed as the new world's record.

The Ukr.S.A expedition in August re-explored and thoroughly surveyed this part, and found the second siphon to be at 1775m instead of 1830m claimed. The attempt has been made to dive the second siphon, the deepest diving operation ever made in caves. By reaching a squeeze at a depth of 10m under water the depth of this branch was established at -1780 m. The siphon continues down almost vertically behind the squeeze.

Meantime, the detailed investigation of side passages through the whole deep section between the two siphons gave the most important discovery. On August 24 the explorers broke through a nasty side passage to a large new section, which bypassed the siphon at 1770m and steeply led to a still greater depth. On August 25 the team of four Ukrainians, one French and one Spanish (Gennadiy Samokhin, Denis Kurta, Dmitry Fedotov, Julia Timoshevskaja, Bernard Tourte and Sergio Garcia Dils) reached another siphon at -1840m, establishing the new worlds record for deep caves. The newly discovered section has many promising side leads still to be fully explored. It gives a good perspective for further depth advance.

The explorers used four underground camps (at 700m, -1200m, -1400m and 1637m) to support various works through the main part of this immensely deep and complex cave. Some cavers spent continuously two weeks underground in the course of the expedition. Twelve cavers took part in explorations behind the siphon at 1440m.

The expedition has made several discoveries and new explorations in some other parts of the Krubera Cave, provided for detailed topographic, photo- and video documentation of all new sections and conducted a considerable body of scientific research.
