The location of the Northern Mine [spoilers]

[Wehmis]

ok, so in the end of the game, you are given the exact location of the northern mine (N81.6914, W58.3154). I'm just willing to know how did the creators of the game come up with those coordinates. Google Earth shows that there is just endless snow, but you can never be sure if we are supposed to really go and kill all the infected ones from the mine out there
So if someone has further investigated this matter, please, share your information with me
