Two-and-a-half miles below the Antarctic surface, Lake Vostok, a fourteen-million-year-old lake sealed off from the rest of the world for eons, is about to be tapped into by Russian drillers.

Currently, the drill sits at nearly 300 feet above the lake. Read more here, or check out Matador’s own guide at penetrating Antarctica yourself.
