Krubera Cave, the deepest known cave on Earth

DAMMMMMMMMMMMMMMMNNNNNNN

looks great, but i would freak so much if i'm dangling and the lights went out

This reminded me of journey to the center of the earth :)

interesting, deepest point so far is 2,197m below the entrance, a team from 9 countries spent 27 days inside exploring it in 2012

To much like the descent for comfort.
