Glacial striae, roches itioutonnees and ice movements
observation points its course is interpolated and shown as a
stippled line. It is obvious that the glaciers followed the al-
ready-existing valleys. In the cirques, which often open directly
to the sea, the roches moutonnees show not only ice movement
out of the cirque but also downwards towards its bottom. In
the open, through-going valleys, of which a number continue
as fjords, e. g. Trongisvágsdalur — Trongisvágsfjørður, the
orientation of both roches moutonnees and striae reflects the
winding course of the valley. No striae, roches moutonnees or
other signs of glaciation have been found showing other oriem
tations, and it must therefore be concluded that throughout
the whole ice age the direction of movement of the ice was
determined by the pre-Glacial landscape morphology.
