While I was on that cycling ride in Bethel last week I snapped this pic of a ROCHE MOUTONNEE. Two actually.
It is a French term : roche= rock. moutounnee = something, i don't know i'm not French. my French-English earth science dictionary defines it as 'ice smoothed rock, glaciated knob'
Its often referred to as a 'sheep back' or 'whaleback', I have heard both.
They are glacially shaped so, tn this case ice sheet movement was from right to left. The ice ramps up the low angle side and will 'pick off' material on the steep side. Aerodynamic, if you will.
Anyway, its also a nice picture.
