The Krubera Cave became the deepest-known cave in the world in 2001 when the expedition of the Ukrainian Speleological Association reached a depth of 1,710 m (5,610 ft) which exceeded the depth of the previous deepest known cave, Lamprechtsofen, in the Austrian Alps, by 80 m.
“Voronya Cave” means “Crows’ Cave” in Russian. This name was used as a slang name by Kiev speleologists during the 1980s due to a number of crows nesting in the entrance pit. The original name “Krubera” had been assigned to the cave by Georgian speleologists who explored the entrance pit in 1960. This name was given after the noted Russian geographer Alexander Kruber.
