The West Norwegian Fjords - Geirangerfjord and Nærøyfjord site was inscribed on the World Heritage List in 2005. The site's two fjords, among the world's longest and deepest, are considered archetypical fjord landscapes and among the most scenically outstanding anywhere. Their exceptional natural beauty is derived from narrow and steep-sided crystalline rock walls that rise up to 1,400 meters from the Norwegian Sea and extend 500 meters below sea level. The site features geological structures such as submarine moraines (undersea remnants of glacial activity), as well as colonies of seals (Phoca vitulina) and porpoises (Phocoena phocoena).
