The discovery of  Gamburtsev Mountains, of  the size of the European Alps, but totally buried beneath the Antarctic ice since 1950 has made scientists guessing about the mystery shrouding these extraordinary natural features.

A recent survey now suggests the range first formed over a billion years ago,  long before complex life had formed on the planet, when the then continents were drifting together to create a giant landmass known as Rodinia.

The resulting collision pushed up the mountains, and also produced an underlying thick, dense "root" that sat down in the crust. Over the course of hundreds of millions of years, the peaks would have gradually eroded away. Only the cold root would have been preserved.
