Scientists uncover vast gorge stretching at least 466 miles believed to be millions of years old

A vast gorge in the Earth on the same scale as the Grand Canyon lies buried under ice in Greenland, scientists have learned.

The massive hidden canyon is at least 466 miles (740km) long and up to 800 metres (2,600ft) deep in places.

The feature, resembling a meandering river channel, is believed to pre-date the ice sheet that has covered Greenland for millions of years.

Prof Jonathan Bamber, from the school of geographical studies at the University of Bristol, said: "With Google Streetview available for many cities around the world and digital maps for everything from population density to happiness, one might assume that the landscape of the Earth has been fully explored and mapped.

"Our research shows theres still a lot left to discover."

The canyon was uncovered by airborne radar which can penetrate ice and bounce off the land beneath.

Scientists pieced together radar measurements covering thousands of kilometres collected by Arctic researchers over several decades. They found evidence of a fissure in the bedrock stretching northwards almost from the centre of Greenland.

The canyon ends in a deep fjord connecting it to the Arctic ocean.

Prof David Vaughan, from the British Antarctic Survey based in Cambridge, another member of the team whose findings appear in the journal Science, said: "A discovery of this nature shows that the Earth has not yet given up all its secrets. A 750km canyon preserved under the ice for millions of years is a breathtaking find in itself, but this research is also important in furthering our understanding of Greenlands past.
