Another Roche Moutonnee
This is a fantastic photo of a very large roche moutonnee on the coast of Milne Land, East Greenland, taken (very recently) by Chris Sugden during a trip in the ice-strengthened vessel called "Sea Bear".

Another consequence of global warming......
Anyway, on this photo there is not much doubt about the direction of ice movement during past glacial episodes......
