That karst is (internationally used term, originally the german form of the slavic word kras or krs, meaning a bleak waterless place; it is the german name for a district east of trieste having such terrane.) a terrane, generally underlain by limestone or dolomite, in which the topography is chiefly formed by the dissolving of rock, and which may be characterized by sinkholes, sinking streams, closed depressions, subterranean drainage, and caves [10]. the term karst unites specific morphological and hydrological features in soluble (mostly carbonate) rocks. morphological features include karren, dolinas (sinkholes), jamas, ponors, uvalas, poljes, caves, caverns, etc. hydrological features include basins of closed drainage, lost rivers, estavelles, vauclusian springs, submarine springs, more or less individualized underground streams and incongruity of surface and underground divides. karst is understood to be the result of natural processes in and on the earth's crust cause by solution and leaching of limestones, dolomites, gypsum, halite, and other soluble rocks [20]. synonyms: (french.) karst; (german.) karst; (greek.) karst; (italian.) carso, carsismo; (russian.) karst; (spanish.) karst; (turkish.) karst; (yugoslavian.) krs, kras. see also buried karst; cone karst; covered karst; exhumed karst; halbkugelkarst; holokarst; kegelkarst; merokarst; microkarst; naked karst; paleokarst; pseudokarst; relict karst; spitzkegelkarst; subjacent karst; syngenetic karst; thermokarst; tower karst.?

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

February-March 2005 expedition news

The next regular expedition of the Ukrainian Speleological Association to Krubera (Voronja) Cave has been carried out between February 9 – March 16, 2005. The expedition, led by Yury Kasjan and composed of cavers from Kiev (N. Solovjev and M.Bondarenko) and Novaja Kakhovka (D.Fedotov and E.Kononov), was the part of the ongoing "Call of the Abyss" project, run by the Ukr.S.A since the year of 2000.

The main goal of the expedition was to systematically explore the deepest section of the cave discovered during the previous Ukr.S.A. expeditions in August and October 2004. There were many open side leads left unchecked in the Windows Series between the Big Junction at –1790m and the Game Over Chamber, the deepest point at –2080m (see the cave profile by following this link).

The expedition has been brought to the cave by a helicopter on February 14.

The team have continuously worked in the cave during 19 days, since February 16. After return to the surface on March 6, the team had to wait out bad weather in the mountains during six days to be picked up by a helicopter.

During descend and ascent the team used established camps at –700, -1215, -1410 and –1640m. It took eight days to restore and improve all the rigging through the cave and to transport materials and supplies to the lowest camp set at the Big Junction at –1790m. Six days were spent for the work in the lower section, and it took five days to get back to the surface.

The results of current explorations in the lower section of the cave can be briefly summarized as follows:

1) Many windows and side leads have been checked within the –1700m - -2080m interval. Almost all of them have looped to the known passages and pits, while some ended by impenetrable squeezes. The only window in the bottom chamber (Game Over), visible in the wall at some ten meters above the floor, has been also checked (dead-ended).

2) The siphon ("Kvitochka") in a side passage at –1980m has been dived through by Nikolay Solovjev. The siphon 10m long and 4m deep gave a continuation explored to a next vertical pitch. This is now the main direction for the further exploration. The dive was the deepest diving operation ever made in caves.

3) Two siphons in side passages near the Big Junction (around –1800m) have been tested.

One of them has been dived for 7m in length and 3m in depth; it continues by an ascending leg. Another siphon (6m long, 2m deep) has connected to the known passage. The terminal siphon at –1840m, which stopped the exploration in August 2004, has not been attempted as it apparently connects to a known passage in the "Windows" series.

4) The temperature measurements have been carried out through the cave to study temperature gradients. The air temperature rises through the cave from 2.1 grad C at –90m to 7.7 grad C at –2080m, giving the overall gradient of 0.28 grad C/100m.

During 2005 the Ukrainian Speleological Association will continue systematic explorations in Krubera Cave and other caves of the Ortobalagan valley in Arabika in August and September-October. Another expedition of the "Call of the Abyss" project is planned for July to the Aladaglar massif in Turkey.
