Valley discovered under Antarctica

Using ice-penatrating radar over 1,500 miles long strech of ice, researchers studying ice loss on Antarctica have discovered a "Grand-Canyon-sized" valley beneath the glacial layer. From CNN:
“If you stripped away all of the ice here today, you’d see a feature every bit as dramatic as the huge rift valleys you see in Africa and in size as significant as the Grand Canyon," the lead researcher, Robert Bingham, a glaciologist at the University of Aberdeen, said in a press release.
Apparently the valley makes it possible for the warmer ocean waters to speed the melting of the glacier. The valley is on the western part of the continent.
