Scientists discover Alps-scale mountain range under Antarctic ice

Scientists have discovered a massive mountain range, the size of the Alps and named the Gamburtsev range, two miles under the world's largest ice sheet in the Antarctic.

If we don't really know the topography under the Antarctic ice sheet, how can we claim to know the volume of the Antarctic ice?

The majority of the ice, 29 × 106 cubic kilometers (approximately 7 million cubic miles), is in Antarctica.
