An ancient river bed that has been unseen for 185,000 years has been found in the English Channel during an underwater mapping survey intended to be completed for the 2012 Olympics.
The mysterious river bed cuts through bedrock at the bottom of the ocean and is eight miles long, ranges between 90 to 150 yards wide and up to 30ft deep Scientists believe it would have flowed when Britain was still attached to the continent.
As ice melted and refroze, it was washed over and uncovered a second time, before finally being hidden at the bottom of the sea during the last Ice Age 12,000 years ago.
As well as the river bed, shipwrecks, rugged cliffs and massive gravel dunes have also been highlighted using the new techniques which can pinpoint objects to within six inches.
