Built in 1959 by the U.S. Army Corps of Engineers, the facility sits at least 100 feet below the surface, and its structures have been protected by ice accumulation for decades.
Using the UAVSAR radar system, which provides a detailed multi-dimensional map of the ice, scientists discovered structures previously invisible in past surveys. The radar’s ability to image the inner layers of the ice sheet provided a clearer picture of the century, revealing tunnels and structures that matched historical maps of the base.
