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.

Scientists now have a clearer picture of Camp Century, an abandoned U.S. military base long hidden under the ice in Greenland, thanks to a NASA research team's good luck.

What’s old is new again. NASA scientists discovered an underground “city” buried 100 feet beneath the ice of Greenland.

NASA scientists accidentally uncovered Camp Century, a hidden Cold War base under Greenland's ice, using advanced radar technology in April 2024. This discovery not only brings historical artifacts to light but also assists in ice sheet studies critical for understanding future sea level changes.

Several months ago, scientist Chad Greene was flying aboard a Gulfstream III with engineers in an effort to monitor a radar instrument on the Greenland Ice Sheet. Flying over northern Greenland, Greene was able to photograph the ice sheet from the aircraft window. This image led to the discovery of something buried under ice.

NASA scientists have found the remains of a U.S. military base buried 100 feet below the surface of the ice in Greenland. Camp Century, as it was called, was a Cold War-era satellite for the U.S. Army used as a front for a planned arsenal of nuclear missiles.

"In the new data, individual structures in the secret city are visible in a way that they've never been seen before," said NASA cryospheric scientist Chad Greene, who was aboard a Gulfstream III jet carrying the radar when Camp Century was detected.

NASA scientists have discovered the former military base Camp Century in Greenland. The discovery was made during tests of a device used to study the interior of glaciers. Although the base's existence was no longer a secret,
