Camp Century
The U.S. Army built Camp Century, a nuclear-powered base, inside the ice sheet by digging deep trenches and then covering them with snow. The base held 200 men in bunkrooms heated to 72 degrees Fahrenheit (22 Celsius). It was the center of U.S. Army research on snow and ice.
Project Iceworm
The Army also imagined hundreds of miles of rail lines buried inside Greenland’s ice sheet. On Project Iceworm’s tracks, atomic-powered trains would move nuclear-tipped missiles in snow tunnels between hidden launch stations – a shell game covering an area about the size of Alabama.
In the end, Project Iceworm never got beyond a 1,300-foot (400-meter) tunnel the Army excavated at Camp Century.
