The hidden canyon is up to half a mile deep, six miles wide and stretches for 466 miles beneath the country’s giant ice sheet.
It is thought to have been carved out by a meandering river more than four million years ago – at a time before ice covered the area and humans were just beginning to evolve from primates.
