Using data collected by aerial flights, satellite technology, and research ships over 50 years, British researchers were able to illustrate mountain peaks that are the size of the European Alps but are hidden below thousands of feet of ice. Less than 1 percent of the continent’s rock base is currently visible above the ice, which is three miles thick in places.
