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

October 2004 expedition news

The Ukrainian Speleological Association is happy to inform speleologists around the world about a historic accomplishment: the first 2000m+ cave on Earth became a reality. The 2000m milestone in deep cave explorations has been vanquished in Krubera Cave, Arabika Massif, Abkhazia, during the third expedition of "The Call of the Abyss" project in the year of 2004, conducted between October 1-28.

The expedition led by Yury Kasjan was composed of nine Ukrainian cavers representing caving clubs of Yalta, Kiev, Kharkov and Uzhgorod (Igor Ishchenko, Sergey Bogutsky, Dmitry Furnik, Kyryl Gostev, Ilja Lapa, Ekaterina Medvedeva, Emil Vash and Shantor Chervits). The main goal was to continue exploring the new section discovered by the previous Ukr.S.A. expedition in August.

Based in the camp at 1645m behind the first sifon, the group of five cavers explored a lead deviating from the main branch some 55m above the terminal sifon. The newly explored part, named Windows, consist of a series of inclined passages and vertical pits (up to 40m deep), which form a complex structure in plan and profile of the total length of 1070m and depth of 290m. No big stream (active collector) has been encountered so far. The new part ended with a dry chamber (named Game Over) plugged with sandy and silt sediments. There are many side openings through the Windows series suggesting good possibilities for further exploration, including advance in depth.

Based on a standard topographic survey made during the August and October expeditions (Suunto compass & clinometer and DisoLite laser distometer; BCRA Grade 3-4) of the post-sifon section below -1440m, added to the previous Ukr.S.A. survey for the whole cave, the total depth of the cave is found to be of 2080m. The 2000m mark and the lowest point were reached on October 19.

With the entrance located at the altitude of about 2250m, the deepest point of the cave has reached the altitude of 170m above sea level, but it has not reached the top of the phreatic zone yet. The system is hydrologically linked to major springs located at 1 to 50m altitudes at the Black Sea coast at the distance of 12-16km, and also to submarine springs. Such a low gradient (less than 170m/13.000m) suggests the low hydraulic resistance of the deep sections of the massif, which is probably because the well developed conduit porosity had formed during Pleistocene periods of low sea level stands, when the drainage level was at much lower position than at present.

The worlds depth record in Krubera Cave was first established at 1710m by the Ukr.S.A. expedition in January 2001. During this year the advance in 370m has been made, unparalleled in the history of deep cave explorations.

The "The Call of the Abyss" Project will continue exploring Krubera Cave to its ultimate limits, and will seek to grow up another 2000m+ cave in the Aladaglar Massif in Turkey, yet another project study area where Kuzgun Cave has been explored to 1400m this July.
