Not sure this will ever happens... but how incredible would be to dive here! Orda Cave is a gypsum crystal cave found underneath the western Ural Mountains. The mouth is near the shore of the Kungur River just outside Orda, Perm Krai in Russia. The water is so clear, divers can see over 45 meters (50 yards) ahead of them #Top10
