A former American military base buried under more than 30 meters (about 100 feet) of ice, Camp Century, has been spotted by NASA during a flight over Greenland. The base was originally built in 1959 as part of the U.S. Army's Cold War-era operations in the Arctic. It was designed to support scientific research and was equipped with living quarters, laboratories, and even a nuclear reactor, all constructed beneath the ice to remain hidden from potential adversaries. Camp Century was abandoned in the 1960s as the ice shifted and the structure became unstable. Over the decades, it has been largely forgotten, buried beneath layers of ice that have accumulated naturally over time. However, recent satellite data and aerial surveys have revealed the base's location, sparking renewed interest in its condition and potential impact on the surrounding environment. Scientists are now concerned about the potential risks associated with the base's reemergence. The nuclear reactor, which was used for power generation, was designed for a limited operational period and may no longer be safe. As the ice continues to melt due to climate change, there is a growing concern that the buried structures could become exposed or even release hazardous materials into the environment. The discovery of Camp Century highlights the long-term consequences of Cold War-era infrastructure and the challenges posed by a warming climate. Researchers are now working to assess the potential environmental and safety risks, as well as the historical significance of the site, which offers a unique glimpse into mid-20th-century military and scientific operations in one of the most extreme environments on Earth.
