Sidelhorn

The Sidelhorn is a mountain of the Bernese Alps, located west of the Grimsel Pass. It lies at the eastern end of the mountain chain between the Unteraar Glacier and the Rhone valley, named Aargrat. Because the glacier drains into the Aar and hence the Rhine and North Sea, whilst the Rhone flows into the Mediterranean Sea, the Sidelhorn lies on the European continental divide.
