Mapping Antarctica’s Invisible Mountain Range
The first detailed maps of a huge and unseen mountain range a mile beneath the East Antarctica ice sheet—the Gamburtsevs—show previously unknown lakes, a network of streams, and deep valleys with unexpectedly steep walls. The new radar maps taken from the air in 2008–2009 cover twice as much terrain as earlier gravity maps and allow scientists to see the topography at unprecedented resolution. This close-up view will provide insights into the ice sheet’s past and future.
