Here\u2019s what you\u2019ll learn when you read this story:<\/p>\n
NASA scientists have found the remains of a U.S. military base buried 100 feet below the surface of the ice in Greenland.<\/p>\n
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.<\/p>\n
While the plan never came to fruition and the base was shortly abandoned, there are still thousands of gallons of nuclear waste buried beneath the ice.<\/p>\n
Over the years, we\u2019ve dug up a lot of stuff buried underneath layers upon layers of ice. Ancient tools<\/a>, animal corpses<\/a>, World War II planes<\/a>, volcanoes<\/a>\u2014you name it, ice has buried it, and we\u2019ve found it.<\/p>\n During an April 2024 flight over the Greenland Ice Sheet<\/a>, NASA scientist Chad Greene added a pretty surprising entrant to that list: a secret military base. After taking radar images of the ice, Greene was surprised to see what was shortly thereafter confirmed to be Camp Century\u2014a 65-year-old Cold War United States military base buried 100 feet deep in the massive ice sheet.<\/p>\n \u201cWe were looking for the bed of the ice and out pops Camp Century,\u201d said Alex Gardner, a cryospheric scientist at NASA\u2019s Jet Propulsion Laboratory (JPL), who helped lead the project. \u201cWe didn\u2019t know what it was at first.\u201d<\/p>\n Built in secret between June of 1959 and October of 1960 by the U.S. Army Corps of Engineers, Camp Century\u2014also known as \u201cthe city under the ice\u201d\u2014was comprised of 21 underground tunnels<\/a> spanning 9,800 feet, according to Interesting Engineering<\/a>. In radar images of the site, Greene said, many of the base\u2019s individual structures are clearly discernable. To study the base, NASA used Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), a technology similar to LiDAR that is commonly used in searching for hidden structures like Maya ruins<\/a>. The difference is that where LiDAR uses laser light, UAVSAR uses radio waves.<\/p>\n The U.S. and Denmark signed the Defense of Greenland agreement in 1951 \u201cto negotiate arrangements under which armed forces of the parties to the North Atlantic Treaty Organization may make use of facilities in Greenland in defense of Greenland and the rest of the North Atlantic Treaty area,\u201d according to the National Museum of Nuclear Science and History<\/a>. (Greenland was, at the time of the agreement, a county of Denmark). This allowed the U.S. to build bases in Greenland.<\/p>\n Even without the -70 degree temperatures and 125-mile-per-hour winds that were possible on the ice shelf, the construction of Camp Century sounds like a total nightmare. The camp was built from 6,000 tons of material, transported via heavy bobsleds that topped out at two miles per hour. Materials were shipped to Thule, another U.S. base (this one above ice)\u2014on the sleds, that trek was a 70-hour trip.<\/p>\n Army engineers first dug trenches\u2014the longest of which was a 1,000-foot-long passageway called Main Street\u2014deep in the snow and ice before wooden buildings and steel roofs built out Camp Century.<\/p>\n The crown jewel of the base was one of the first PM-2 medium-power nuclear reactors<\/a> that, in the freezing conditions, had to be treated with the utmost care in order to power the site.<\/p>\n While operating at the base, scientists made major geological breakthroughs. They were some of the first to study ice cores, and soil from Greenland<\/a> itself revealed an ancient history of verdant forestry and diverse wildlife.<\/p>\n But that research was just a cover-up.<\/p>\n Camp Century itself was not a secret. Its establishment was known, and the Army even made a promotional video for the project. The scientific research angle, as significant as the discoveries were, was merely a front for a major U.S. nuclear weapon strategy<\/a> of which the Danish government wasn\u2019t even aware. Known as \u201cProject Iceworm,\u201d the plan was for Camp Century to house ballistic missiles under the Greenland ice. An additional 52,000 square miles of tunnels were planned\u2014enough to fit 600 missiles. It would require 60 launch centers to be built, and would be manned by 11,000 soldiers living full-time in the city under the ice.<\/p>\n If that sounds impossible on a number of levels to you, you\u2019re not alone. Project Iceworm never came to be because of a litany of obstacles, almost all of them boiling down to some version of \u201cwell, this simply isn\u2019t feasible.\u201d By 1967, Camp Century was decommissioned and abandoned\u2014a frigid fossil of the U.S.\u2019s Cold War efforts. The potential nuclear weapon<\/a> plan was publicized by the Danish Institute of International Affairs in 1997.<\/p>\n So, now the remains sit alone, buried by even more ice and snow in the 57 years since the closure of the base and giving its \u2018Camp Century\u2019 name even more significance. Ultimately, it\u2019s just a harmless footnote in U.S. military history. Right?<\/p>\n Well, not exactly. As is U.S. tradition during international ventures, there were some residual drawbacks. Remember that nuclear reactor that was lugged piece by piece below the ice, only to operate for 33 months? Well, during that time, it produced over 47,000 gallons of nuclear waste<\/a>, according to the National Museum of Nuclear Science and History. When the base shut down, they removed the reactor, but not the waste, which is still lying under the ice\u2014ice that is in serious peril with a warming climate. Right now, it\u2019s just sitting there, frozen in time. But a study<\/a> by experts has projected that the base could begin losing ice by 2090.<\/p>\n
