Krubera-Voronja is, to date, the deepest cave on Earth
The Krubera ( Krubera Cave ), also known as Voronya Cave (Russian for the "Corbeal Cave") is the deepest natural cave on Earth known until today. This swell is located in the Arabika massif, one of the largest karst mountains in the western Caucasus region, Georgia . These mountains contain several hundred caves that began to grow when the mountains began to rise more than 5 million years ago. Five of these caves are deep over 1000 meters, and Krubera's cave is measured 2197 meters depth and is the only cave known on Earth over 2000 meters deep.
The Krubera Cave is a 16,058-metre long cavity system which, for the most part, consists of deep vertical wells that are interconnected with passages. The cave finds its high opening in the mountains, at an altitude of 2256 meters, with a narrow entrance. The inside of the Krubera cave is often very narrow and must have been cut into many places to make the passage safely. But in some places, passage is bigger than a metro tunnel .
At 200 metres deep, the cave is divided into two main branches: Non-Kuybyshevskaya (explored up to 1293 m in 2008) and Main (2197 m depth). At 1300 meters deep, Krubera is still divided into many branches. When the speleologists began to explore the cave, one of the difficulties they were confronted was flooded tunnels called "pull". When they met a cockroach (bassin), the speleologists had to filter their diving equipment and go forward. One of these basins, the deepest, was measured at 52 m of depth.
The cave is now a very popular destination for expeditions from many countries.
