NASA scientists conducting surveys of arctic ice sheets in Greenland got an unprecedented view of an abandoned "city under the ice" built by the U.S. military during the Cold War.
During a scientific flight in April 2024, a NASA Gulfstream III aircraft flew over the Greenland Ice Sheet carrying radar instruments to map the depth of the ice sheet and the layers of bedrock below it. The images revealed a new view of Camp Century, a Cold War-era U.S. military base consisting of a series of tunnels carved directly into the ice sheet.
