... a major part of the spookieness of the Cold War was all the secret and stupendous stuff going on in the Arctic. ( think 'The Thing' from 1951) 'Camp Century' was a major construction project by the US Army in Greenland. The true purpose was to study the feasibility of hiding nuclear tipped ICBMs under the ice. Consideration was also given to having mobile launcher systems that could move the missiles around in frozen tunnels.
In the end US nuclear forces found out the hard way that all that ice was not stable. It was slowly moving and shifting which eventually destroyed all the construction work.
... here's another scary story set in the freezing darkness of a remote Arctic base.
'The Human Factor' from the original 'Outer Limits'.
