Deep beneath Greenland’s ice sheet, the U.S. Army once operated one of the Cold War’s most unusual bases.
It was called Camp Century.
Instead of building on the surface, engineers carved long trenches into the snow, covered them with steel arches and packed snow over the top.
The camp eventually included 21 major trenches, with its main corridor stretching nearly 1,200 feet.
Inside were living quarters, work areas, laboratories and equipment facilities.
But the most remarkable feature was its power source.
A portable nuclear reactor known as PM-2A was transported to Greenland in sections, assembled at Camp Century and used to provide electricity and heat.
For a short period, the United States operated a nuclear-powered military installation beneath one of the most remote ice sheets on Earth.
