Operated from 1959-67, Camp Century was abandoned after officials realized the ice wasn’t as stable as previously thought. Since then, it’d largely been forgotten about – that is, until NASA accidentally captured an image of the subterranean base in April 2024.

As it turns out, this abandoned "secret city" was the site of a secret Cold War project known as Project Iceworm which called for the construction of 2,500 miles (4,023 km) of tunnels that could be used to nuclear intermediate range ballistic missiles (IRBMs) at the Soviet Union.

The CIRES-led study used ground-penetrating radar to estimate the amount of waste under the ice. The team found that the waste at Camp Century covers about 136 acres, about the size of 100 football fields, and contains an estimated 53,000 gallons of diesel fuel and 63,000 gallons of wastewater.

NASA's radar revealed Camp Century, a Cold War base under Greenland's ice. It provides data on ice sheet melting and rising sea levels.

Scientists flying in a NASA Gulfstream III jet to measure Arctic ice with a radar therefore got something of a surprise when they found just such a secret base, long since given over to the elements and buried deep under the ice sheet of Greenland.

NASA scientists unearthed an astonishing man-made spectacle, lying frozen 100 feet below the surface and frozen in secrecy and ice. The post NASA Finds Secret Underground “City” Hidden From The World Under 100 Feet Of Ice And Snow first appeared on Bored Panda.
