Krubera is the world's deepest cave located in Abkhazia, Georgia.

Iran PressAsia: The world of caving is sort of a story of two — two caves and two men. The two caves are Chevé in the state of Oaxaca, Mexico, and Krubera in the Arabika Massif of the Western Caucasus in Abkhazia, Georgia.

The two men are American Bill Stone, who has been exploring Chevé for well over a dozen years, and Ukrainian Alexander Klimchouk, who has been exploring Krubera since the 1980s, Interesting Engineering reported.

Since the beginning of the millennium, it has been a race to the bottom of the Earth, and the story of both men was told in James Tabor's 2010 book Blind Descent: The Quest to Discover the Deepest Place on Earth.

Until March 2018, Krubera, named for the Russian geographer Alexander Kruber, won the depth race. According to Geologypage, "the difference in elevation of the cave's entrance and its deepest explored point is 2,197 ± 20 meters (7,208 ± 66 ft)."

The entrances to the two caves couldn't be more different. While Chevé's is hundreds of feet wide, the entrance to Krubera is little more than a hole in the ground.
