These beautiful clear glass like pillars. Right next to it, this really delicate. Look at a finger that. Filament is there. As the cave team explore deeper, each chamber reveals ice crystals more strange and spectacular than the last. No one on the team imagined a single Antarctic mountain could house so many wonders.

Down at the foot of Mountain Alps, a third crew, the diving team, plan to explore the volcano's belower slopes, which extend beneath the frozen sea. On board is the underwater cameraman, Hue Miller. From what we actually know, under the ice sea, said he knows this is his favorite adventure. Old fashion tools still work best. First a hand chisel to create an open hole, than a saw to widen the hole. Ice diving in the coldest waters on the planet should be taken extremely seriously.
