 The eastern part of the range forms a plateau with some gently sloping mountains, and this is where the road and railway crosses over Saltfjell.Both road and railway take advantage of the Dunderland Valley and the Saltdal valley to make the distance on the alpine tundra, which often sees snowstorms in winter, as short as possible.The western part is more alpine and steep, and this is where the engabreen glacier tongue of Western Svartisen almost reaches down to the fjord.
