I think the nazi's had something going on there, at one of the poles or maybe both im not sure what they were/are doing, possibly there are underground citys or bases there, even maybe the entrances into what people call "inner earth" for those who are familiar with the hollow earth theory. I posted this link on another thread a while ago but ill put it here again, it's about what i just talked about, nazi made maps of it and letters.
