Mysteries of Antarctica

McMurdo is actually a pretty big station when you look at it from above. There are certain parts of Antarctica that countries make claims on. New Zealand of all places claims the Ross Ice Shelf.

Nothing really secret. Many nations feel that there are untapped resources in Antarctica and don't want to spill the beans about oil or mineral deposits. Most of what people suppose about Antarctic mysteries are taken from shitty and predictable novels like the ones by Clive Cussler where Dirk Pitt or his son or whoever finds the bodies of King David and Adolph Hitler buried with the Ark of the Covenant and the Amber Room below the Antarctic ice.

How do you personally know nothing is being kept secret? We're talking about the same government that is responsible for MKultra mind control experiments, the Tuskegee syphilis experiment, NSA spying on average citizens, Operation Northwoods, etc, etc. No disrespect bubba but don't be so naive to think it's impossible.

The ancient weapon that SG1 used to defend earth is still down there.

What do you think they would be hiding? Something supernatural? Top secret nuclear or biological testing? True, the Navies of several nations patrol the waters north of the South Pole and prevent civilian traffic from making land. Partly due to poaching of penguins illegally for zoos and aquariums. I guess part of the other reason is someone making land and getting stuck. The waters and weather are treacherous and mounting a rescue operation would be dangerous and costly.
