The boundary follows thee e watershed - thee line of highest elevation that separates rivers flowing westward t te Atlantic Ocean from those flowing eastward to thee Baltic Sea.

This watershed is marked by numeruos glacial landforms such as arêtes, horns, and U- shaped valleys that provide natural and clear divideng lines. The Jostedalsbreen Glacier, the largett glacier in continental Europe, lies close to but does not cross the border, conteing the natural separation.

Te border was formalized through gh treaties in 1751 and 1905, with the watershed chosen for it s natural barrioner qualities. Today, cairns andd physical markes alonge the ridge complement the underlying glacial exacures, which remain the true topographical boundary.
