Saltfjellet is a mountain area in Nordland county, Norway that separates the two regions of Helgeland and Salten.

[1] The Saltfjell is one of the largest mountain ranges in Norway, and is also where the Arctic Circle cuts through the country.

Western Svartisen is the second largest glacier on the Norwegian mainland, and is part of the Saltfjellet-Svartisen National Park.

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.

The railway line was built over the mountain during World War II and opened in 1947.
