The U.S. Army's Top Secret Arctic City Under the Ice! "Camp Century" Restored Classified Film
In the late 1950s, during the height of the Cold War, the US military constructed a secret base in the Arctic for "research" purposes.
Some theorists claim that it was actually used as a covert nuclear weapons storage and/or testing facility as part of Top Secret "Project Iceworm" with the ultimate objective of covertly placing medium-range missiles under the ice sheet -- close enough to strike the Soviet Union, while remaining hidden from the Danish government.
Others have made even grander claims - that Camp Century was actually a weather manipulation experiment ... or a U.S. Military administered Alien / UFO base!
The whole truth may never be known.
This video is the actual declassified US ARMY FILM documenting the construction process.
What really happened there afterwards remains a mystery.
