A Giant Is Lurking Beneath Antarctica’s Ice

January 15, 2014

Hidden beneath ice in Antarctica, scientists have discovered a massive and ancient subglacial trough, even deeper than the Grand Canyon. This team of UK researchers was charting an ancient mountain range called the Ellsworth Subglacial Highlands that are buried beneath several kilometers of Antarctic Ice using satellites and radars when they discovered the deep valley. The subglacial valley is up to 3 kilometers deep, 300 kilometers long, 25 kilometers across and in some places reaches more than 2000 meters below sea level. Researchers say the find was “incredibly serendipitous” and “that it just goes to show how little we still know about the surface of our own planet.”
