Close Krubera (Voronja) Cave: the first 2000m+ cave on Earth

August-September 2010 Expedition news: The Nekujbyshevskaya Branch has been pushed to -1697 m

In the period of August 5 September 3, 2009, the Ukrainian Speleological Association have conducted the next regular expedition of the CA project to continue exploration of Krubera (Voronja) Cave and other caves of the Ortobalagan Valley in the Arabika Massif (Western Caucasus).

The group of 5 cavers led by Yury Kasyan continued exporing the Nekujbyshevskaya Branch in Krubera, building on the achievements of recent years there. Nekujbyshevskaya is a distinct branch that diverges from the main one at -250 m and stretches to the north-west, in the direction opposite to the overall trend of the Main Branch. Starting from the depth of about -750 m, the Nekujbyshevskaya Branch turns to south-east and stretches toward the deep section of the Main Branch.

In 2009, the Ukr.S.A. expedition has reached depth of -1,557 m in the Nekujbyshevskaya part.

After passing a 2-m long sifon that terminated exploration in 2009, the group has pushed the cave for 140 vertical meters, to a next (narrow) sifon. This has increased depth of the Nekujbyshevskaya Branch to -1,697 m. The group has also discovered and mapped two new passages at the level of about -1,300 m, adding almost 300 m to lenght.

The total length of the Krubera Cave became 16.058 km. The total depth remains at -2,191 m, as established by a 46 m deep dive in the terminal siphon in the Main Branch performed during the 2007 Ukr.S.A. expedition.
