This shows the facility built by the United States government in the 1960's called Camp Century. "FYI, Camp Century was built as part of a series of nuclear missile launch sites that were built without the knowledge of the people or government of Denmark, who controlled Greenland at the time. The facility operated under the facade of a scientific outpost, but was actually a mock military installation that was purposely built within firing range of the Soviet Union to test the feasibility of arctic nuclear launch sites and extend the U.S.'s nuclear strike capabilities."
Camp Century History Page Type: Cold War History Date: Thursday, July 19, 2018 Legacy "The U.S. Army continued to operate Camp Century in a limited capacity until 1966. Its tunnels quickly collapsed, and today the facility is unreachable, buried under a thick layer of ice. Project Iceworm remained a closely guarded secret until 1997, when the Danish Institute of International Affairs (DUPI) reported Camp Century’s military ambitions." "In recent years, climate change scientists have warned of severe consequences should the Greenland ice sheet melt enough to reveal Camp Century. During its operation, the facility’s nuclear reactor produced over 47,000 gallons of radioactive waste. Although the reactor was removed, this waste remains buried under the ice to this day. As climate scientist William Colgan explained, “They thought it would never be exposed. Back then, in the ‘60s, the term global warming had not even been coined. But the climate is changing, and the question now is whether what’s down there is going to stay down there.” Some scientists have predicted that the Camp Century site will start losing ice by 2090."
Talking about an expensive underground water filled tunnel........... That was a very interesting article!
