A team of cave divers have taken an unbelievably awesome photographs of the longest underwater gypsum crystal cave in the world.

The Orda Cave in the western Urals region spans three miles, making it the largest underwater gypsum cave in the world. The water is so clear that divers can see up to 50 yards ahead of them.

The Cave is also the biggest underwater gypsum crystal cave in the world and second in Eurasia in terms of volumes of its galleries that stretch up to five kilometers.

Famous underwater photographer, journalist and dive-instructor Victor Lyagushkin led the team of cave divers and took stunning images of the cave at less than zero degree temperature.

There is extremely low water temperature, about 3C and 20C below zero on surface. Under these circumstances shooting became very challenging, Lyagushkin said.

The Ural region, which is known for rich mineral deposits in Russia, is located around the Ural Mountains, and sits between East European and West Siberian plains.
