Expedition set for 'ghost peaks'
It is perhaps the last great Antarctic expedition - to find an explanation for why there is a great mountain range buried under the White Continent.
The Gamburtsevs match the Alps in scale but no-one has ever seen them because they are covered by up to 4km of ice.
Geologists struggle to understand how such a massif could have formed and persisted in the middle of Antarctica.
Now, an international team is setting out on a deep-field survey to try to get some answers.
The group comprises scientists, engineers, pilots and support staff from the UK, the US, Germany, Australia, China and Japan.
