An ongoing joint expedition of caving clubs from several Siberian sities to Sarma Cave in the Arabika Massif (Western Caucasus), led by Pavel Rudko, has reported that the cave has been pushed 60 m below the previous deepest point (-1760 m) reached last year. This firmly establishes Sarma Cave as the second deepest cave in the world with depth of 1830 m, following Krubera Cave located in the same massif, which has been explored this August to -2197 m by the Ukrainian expedition. The third place holds Snezhnaya Cave in the nearby Bzybsky Massif, with depth of 1760 m.
