Going to Voronya...
Voronya (so called on account of the ravens at the entrance) is officially called Krubera and is found in the Arabika Massif of the Caucasus. There are plenty of sites having information in various languages, and I'll get a list of links made up as soon as possible.
Purpose of the blog is to chart the mission being conducted with the participation of three boys from SELAS, the Speleological Hellenic Athletic Club. The plan is to map the recent advances made in the cave, especially from about -1400 to the bottom (currently at -2080).
The participation of SELAS is kindly sponsored by TNT.
