The Lake Vostok Research Facility (Russian: Научно-исследовательская Озеро Восток) was located in Lake Vostok, Antarctica before it was abandoned and destroyed.
History[]
Brainiac explains the geyser is pumping out three cubic miles of water every second. At that rate, every coastal city in the world will start flooding in 12 minutes. The loss of life could be in the billions. Supergirl and J'onn immediately go to Lake Vostok in Antarctica where they fight Rip Roar and are finally able to beat him together. After they must seal the geyser and agree to fly around it together in perfect sync before Supergirl is able to freeze it with her breath. Successful they both head back to the D.E.O. National City headquarters in the United States (Earth-38).[1]
