Scandinavian Mountains: the Scandinavian Mountains are the most defining feature of the country. Starting with Setesdalsheiene north of the Skagerrak coast, the mountains are found in large parts of the country and intersect the many fjords of Vestlandet. This region includes Hardangervidda, Jotunheimen (with Galdhøpiggen at a.s.l.), Sognefjell, and Trollheimen in the north, with large glaciers, such as Jostedalsbreen, Folgefonna, and Hardangerjøkulen. The mountain chain swings eastwards south of Trondheim, with ranges such as Dovrefjell and Rondane, and reaches the border with Sweden, where they have become mostly gently sloping plateaus. The mountains then follow the border in a northeasterly direction and are known as Kjølen (the keel). The mountains intersect many fjords in Nordland and Troms, where they become more alpine and create many islands after they meet the sea. The Scandinavian mountains form the Lyngen Alps, which reach into northwestern Finnmark, gradually becoming lower from Altafjord towards Nordkapp (North Cape), where they finally end at the Barents Sea.
