American McMurdo Station and the Russian Vostok Station would be an instant Antarctic classic.
So Vostok would be a really deadly place to play. It is the worlds coldest place with -89,2 degrees Celcius as record and also at high altitude (3488 meters above sea level) and bone dry (2,6 mm pr year) so people get nose bleeds just being there. -12 degrees Celcius is the warmest ever recorded there, but high summer is normally -32 degrees Celcius in average; winters being -65 to -68 in average)
McMurdo Station is close to sea-level and not even "really cold" (only -49,4 degrees Celcius as record) and has +9,4 degrees Celcius as the warmest recorded.
So if it would give seriously problems for the Americans to play the Russian at Vostok base.
