At the moment Пеще́ра Кру́бера-Воро́нья (Voronya Pestera, Krubera Cave) is the second-deepest cave on earth. The height difference inside the cave is 2,197 m [2021], which is much deeper than the Grand Canyon. While the cave continually grew at the beginning of the millennium, this finally came to an end when the groundwater was reached. The cave extends underwater to the Black Sea, but it's extremely difficult to explore. At the same time several other caves were explored nearby, among them CaveVeryovkina, which actually ends at the groundwater too, but extends further up the mountainside, and so it became the new deepest cave in the world.

In early January 2005 an accident happened, and a helicopter with cavers on board crushed at the cave. The helicopter brought cavers and material when it kicked up a lot of the powdery snow at the landing spot. The pilot could not see the mountain anymore and the rear propeller hit the side of the mountain. The helicopter started to spin on its own axis, three cavers fell out of the rear door and hit the soft snow 10 m below. Finally, the helicopter grounded. There were no casualties, but the three cavers who fell out and the pilot were injured. Some equipment was damaged and the expedition was aborted.
