Islands
editThe 6.1-square-kilometre (2.4 sq mi) island Tjåehkere (Southern Sami) or Gudfjelløya (Norwegian) lies in the lake Tunnsjøen. The island's highest point is 812 m (2,664 ft) above sea level; which is 454 m (1,490 ft) higher than the lake. The peak is named Gudfjellet (lit. 'God's Mountain'). This makes Gudfjelløya the highest island within a lake in Norway (and in Europe). It towers higher than the island of Monte Isola within Lake Iseo, in northern Italy. The island is located in the lake's central part. To the southwest of the island is the lake's second largest island: Sodtsååle (Southern Sami), also known as Litlfjelløya or Reinøya (Norwegian) (lit. 'Little Mountain Island' or 'Reindeer Island'). Its highest point is 177 m (581 ft) above the lake's water surface.[3]
