they are there; we've seen them under the ice. Not only are they similar in dimension to the
European Alps, but they are also similar in aspect: we see very sharp peaks and valleys which are remarkably similar to the Alps themselves. It all adds to the mystery – from the tectonic perspective of how these mountains were created; and from the glacial history perspective of how the East Antarctic ice sheet was formed and didn't erode these peaks."

The team's next goal is to drill through the ice and collect the first
Gamburtsev rock samples. "Amazingly, we have samples of the moon but none of the Gamburtsevs," said Robin Bell, a geophysicist at Columbia University's Lamont–Doherty Earth Observatory. "With these rock samples we will be able to

Scientists announced the completion of their mission on 25 February 2009. Modern-day remote-sensing technology revealed a very jagged landscape. The gathered data will be analysed by researchers in the following months. Dr Fausto
Ferraccioli from the British Antarctic Survey said: "We can confirm
