As NASA scientist Chad Greene flew over northern Greenland with a crew of engineers in April, they by no means anticipated their radar to seek out one thing artifical buried deep inside the ice. Greene and his crew have been flying above the Greenland Ice Sheet on a NASA Gulfstream III aircraft, scanning the barren expanse of ice that’s greater than a mile deep in some areas, when their radar instrument picked up one thing uncommon.
“We didn’t know what it was at first,” Greene stated in an announcement launched by NASA’s Earth Observatory this week, together with new photographs of the invention. “We were looking for the bed of the ice and out pops Camp Century.”
It seems the crew had stumbled upon an deserted Chilly Conflict-era navy base constructed by the U.S. Military Corps of Engineers in 1959. Nicknamed the “city under the ice,” the compound consists of a community of tunnels carved into the ice sheet. It was deserted in 1967 and, over time, grew to become buried about 100 ft under the floor as snow and ice amassed.
The bottom was constructed as a part of Venture Iceworm, a then-secret plan to experiment with constructing a missile launch web site below the Greenland Ice Sheet in the course of the Chilly Conflict, when rigidity soared between the U.S. and the then-Soviet Union. Camp Century, a distant, nuclear-powered set up, was constructed to review the feasibility of such a venture, but it surely was by no means realized and the bottom was decommissioned below the idea it will be buried eternally below the ice.

Whereas the “city under the ice” had been picked up by earlier radar scans, the devices used on the NASA flight in April supplied a extra detailed, if surprising, survey.
“In the new data, individual structures in the secret city are visible in a way that they’ve never been seen before,” stated Greene, who works with NASA’s Jet Propulsion Laboratory.
Previous scans had used a sort of radar that factors straight down on the floor and produces a two-dimensional scan of constructions buried beneath the ice. Greene’s flight used NASA’s Uninhabited Aerial Car Artificial Aperture Radar, which is ready to produce maps with “more dimensionality,” based on the company.
A photograph launched by NASA on Monday confirmed the options of the bottom hidden deep below the ice, showing as anomalies close to the bottom of the ice sheet.

“Scientists have used maps acquired with conventional radar to corroborate estimates of Camp Century’s depth — part of an effort to estimate when melting and thinning of the ice sheet could re-expose the camp and any remaining biological, chemical, and radioactive waste that was buried along with it,” NASA’s Earth Observatory stated in its article this week. “The scientific utility of the new UAVSAR image of Camp Century remains to be seen; for now, it remains a novel curiosity acquired by chance.”
A 2016 examine of the deserted base recommended that the ability may now not be thought of “preserved for eternity,” as a result of local weather change rising the speed at which Arctic ice is melting.
CBS Information’ Walter Cronkite visited Camp Century for a tour of the still-under-construction facility for a program that aired in 1961. The camp’s commander, Captain Tom Evans, defined to him that the targets of this system have been three-fold: “The first one is to test out the number of promising new concepts of polar construction. And the second one is to provide a really practical field test of this new nuclear plant. And, finally, we’re building Camp Century to provide a good base, here, in the interior of Greenland, where the scientists can carry on their R&D activities.”

The precise nature of that analysis and growth work wasn’t mentioned in Cronkite’s report for the CBS documentary present “The Twentieth Century.” (An abridged model of that report may be seen on the hyperlink above.)
Talking with 60 Minutes in 2016, as that present revisited Cronkite’s decades-old journey to Camp Century, producer Daniel Ruetenik stated the journey was fascinating, and he marveled on the evolution of human curiosity within the huge, frozen expanse of the Greenland Ice Sheet.
“At the time [of Camp Century], the Cold War was considered to be the greatest threat to humanity,” Ruetenik stated. “And now, the area has become a destination for climate scientists trying to study changes in the environment. So, it has a second purpose now.”
