What's Really Under Antarctica? 12 Secrets, Only 4 Are Real

Antarctica is bigger than the United States and Mexico combined, buried under ice up to almost five kilometres thick, and for decades people have been sure it is hiding something. Ancient maps. A pyramid. A secret Nazi base. A fleet driven off by something in the sky. A rock with life from Mars. We take twelve of Antarctica's biggest secrets one at a time and look at the evidence for each. Only four are real, and they are stranger than the myths.
