New evidence: Ice formed fast in Antarctica

Reuters brings some interesting news for Decipher fans:

Jagged mountains the size of the Alps have been found entombed in Antarctica’s ice, giving new clues about the vast ice sheet that will raise world sea levels if even a fraction of it melts, scientists said on Tuesday.

Using radar and gravity sensors, the experts made the first detailed maps of the Gamburtsev subglacial mountains, originally detected by Russian scientists 50 years ago at the heart of the East Antarctic ice sheet.

“The surprising thing was that not only is this mountain range the size of the Alps, but it looks quite similar to the (European) Alps, with high peaks and valleys,” said Fausto Ferraccioli, a geophysicist at the British Antarctic Survey who took part in the research.

Ah, but here’s the really interesting bit:

He told Reuters that the mountains would probably have been ground down almost flat if the ice sheet had formed slowly. But the presence of jagged peaks might mean the ice formed quickly, burying a landscape under up to 4 km (2.5 miles) of ice.

So thanks to Charles Hapgood, and the Flem-Aths, and a few others.

Decipher 2 is shaping up to be a lot of fun, by the way.
