Antarctica's Topography

Caption

This 3-D reconstruction of the topography hidden under Antarctica's two-mile-thick coating of ice was made using data from radar surveys. Glaciers started carving Antarctica into the current mountain-and-fjord landscape 34 million years ago, according to new findings from University of Arizona geoscientist Stuart N. Thomson and his colleagues.
