Trough head emergence



A great photo from James Lea, showing the emergence of a trough head at the landward end of an East Greenland fjord.  This is a bit strange, because there is an undoubted trough head, but no obvious ice stream flowing to the edge of it.  Maybe, further in from the ice edge, something has happened to cut off the ice supply?
