WASHINGTON, Oct 24 (Reuters) – Antarctica has not always been a desolate land of ice and snow. Earth’s southernmost continent once was home to rivers and forests teeming with life.

Researchers said on Tuesday they have detected buried under the continent’s ice sheet a vast ancient landscape, replete with valleys and ridges, apparently shaped by rivers before being engulfed by glaciation long ago.
