It is widely known as  Krubera-Voronya cave and rightfully is considered to be the ‘Mount Everest of caves’. This great monument, seemingly, started as a small hole formed in the highest point of a mountain.

In particular, the total length of the passages of the cave reaches the 13,232 meters, while the cave’s depth measures  -2,197 meters.  The marvellous cave is located in Abkhazia, a place in the southern Russia, near to the Black Sea. The highest peak of Krubera is 2,705 meter and is located in the ‘Ortobalagan’ Valley – a comparatively shallow valley formed by a glacier. This mountain range contains a hundred caves, while five of them are deeper than 1,000 meters.  Scientists say that, most likely, these caves started to grow when the mountains began to erode, this phenomenon occurred over 5 million years ago.

During the winter the thick layer of snow closes the narrow entrance of  Krubera Cave, while every spring the melting of ice causes flash floods.  Unsurprisingly, the water of the lake is extremely cold. The cave’s entrance is located very high in the mountains, at an altitude of 2,256 m. Consequently,  at a depth of 100 m. the temperature is just 1 °C, while in the 2,000 m. reaching 7.2 °C. In the winter the flow of the water within the cave is very low, whereas,  in late May and June reaches the upper and the lower parts of the cave, therefore the cave inundates.

Speleologists have probably reached the bottom of the cave  – but, surely,  water’s sources extend beyond this. The deepest point of Krubera cave is located in the  2197 m, just 59 m. over the surface of the sea. So one could presume that this cave it is impossible to be deeper than this point. Research shows, however, that the cave might continue below the sea level.

Over 5 million years ago the Black Sea had almost dried up – and probably many caves formed during this era have ‘survived’ until today. Although, the analysis of stalagmites of Krubera testified that these formations occurred over 200 thousand years.

However, Krubera cave is a miracle of nature. Is an amazing natural phenomenon that leaves every visitor ecstatic.
