Greenland dogs are descended from canines that accompanied immigrants from Siberia some 5,000 years ago. This team, driving across Greenland's Sermipaluk Glacier, is tethered to the sled with a fan hitch, a type of harness that allows each dog to pick its own way across rough and dangerous terrain.
