The Sognefjord or Sognefjorden, nicknamed the King of the Fjords, is the largest and deepest fjord in Norway. Located in Sogn og Fjordane county in Western Norway, it stretches 205 kilometres (127 mi) inland from the ocean to the small village of Skjolden in the municipality of Luster. The fjord takes its name from the traditional district of Sogn, which covers the southern part of the county.
The fjord runs through many municipalities: Solund, Gulen, Hyllestad, Høyanger, Vik, Balestrand, Leikanger, Sogndal, Lærdal, Aurland, Årdal, and Luster. The fjord reaches a maximum depth of 1,308 metres (4,291 ft) below sea level, and the greatest depths are found in the central parts of the fjord near Høyanger. Sognefjord is more than 1,000 metres (3,300 ft) deep for about 100 km of its length, from Rutledal og Leikanger. Near its mouth, the bottom rises abruptly to a sill about 100 metres (330 ft) below sea level. The seabed in Sognefjord is covered by some 200 metres (660 ft) thick sediments such that the bedrock is some 1,500 metres (4,900 ft) below sea level. The fjord is up to 6 km wide. The average width of the main branch of the Sognefjord is less than 5 kilometres (3.1 mi). The depth increases gradually from Årdal to a central basin of more than 1000 meters between Leikanger and Brekke. From Brekke the floor rises rapidly to Losna island, then drops gradually with a threshold at about 150 meter in Solund area. Thresholds occur in an area with sounds, valleys and low land where the glacier was allowed spread out and loose its erosive effect. Cliffs surrounding the fjord rise almost sheer from the water to heights of 1,000 metres (3,300 ft) and more. Around the outer area the land rises to about 500 meters above sea, while in the inner areas around 1600 meters. The inner part has extensive tributary fjords such as Aurlandsfjorden, while the outer part is connected by narrow sounds to neighbouring fjords. Near the coast the fjord mouth is bounded largely by low islands and skerries that are part of the strandflat.
The inner end of the Sognefjord is localized southeast of a mountain range rising to about 2,000 metres (6,600 ft) above sea level and covered by the Jostedalsbreen, continental Europe's largest glacier. Thus the climate of the inner end of Sognefjorden and its branches are not as wet as on the outer coastline. Hurrungane range at the eastern end of the fjord reaches 2400 m. The greatest elevation from sea bed to summit is at Sogndal. Several rivers pour fresh water into the fjord with an annual "spring" flood in June. The mouth of the fjord is surrounded by many islands including Sula, Losna, and Hiserøyna. The Sognefjord cuts through a northwestern gneiss area with a south-west to north-east structure, and penetrates the Caledonian fold through in the inner part. There is no clear relation between the east-west direction of the main fjord and the fold patterns of the bedrock, while some of tributary fjords in the parts corresponds to fold pattern.
There are many smaller fjords which branch off the main fjord.
- Sognesjøen (mouth) (35 km)
- Lifjorden (6 km)
- Høyangsfjord (8 km)
- Arnafjord (8 km)
- Esefjord (4 km)
- Fjærlandsfjord (27 km)
- Sogndalsfjord (21 km)
- Aurlandsfjord (29 km)
- Nærøyfjord (a World Heritage Site)
- Lærdalsfjord (9 km)
- Årdalsfjord (16 km)
- Lustrafjord (innermost) (42 km)
The innermost arm of the Sognefjorden is called the Lustrafjord, located in the municipality of Luster. At its end, there is the village of Skjolden, which is an access point to Jotunheimen National Park. In earlier times, transport between Bergen and the Scandinavian inland was by boat between Bergen and Skjolden and from there on a simple road over the highlands (today Norwegian County Road 55), or by boat to Lærdal and through the mountain pass to Valdres (now European route E16).
Origin and geology
The valley of Sognefjord is one of various valleys of western Norway that certainly predates the Quaternary glaciations. It existed already as part of the ancient Paleic surface but had at the time much gentler slopes. The fjords of western Norway formed in connection to the east-ward tilting of much of Norway during the Cenozoic uplift of the Scandinavian Mountains. This uplift, that occurred long before the Quaternary glaciations, enabled rivers to incise deeply the Paleic relief. An estimate of 7610 km3 of rock has been eroded from the Sognefjord drainage basin since the Paleic surface formed. The fluvial and glacial erosion that made the fjords has followed structural weaknesses in the crust.
During the last glaciation the ice reached a maximum thickness of nearly 3000 meters in the Sognefjord area. Confluence of tributary fjords led excavation of the deepest fjord basin. Until about 30 km from the very coast the Sognefjord glacier was apparently constricted to its narrow channel of homogeneous gneiss, then the glacier suddenly spread out presumably through sounds and low valleys.
Boats connect settlements along the fjord and its sidearms. Larger villages on the fjord and its branches include Leirvik, Ytre Oppedal, Vadheim, Høyanger, Vikøyri, Balestrand, Hermansverk, Sogndalsfjøra, Gudvangen, Flåm, Aurlandsvangen, Lærdalsøyri, Årdalstangen, Gaupne and Solvorn. Gudvangen is situated by the Nærøyfjord, a branch of the Sognefjord particularly noted for its unspoiled nature and dramatic scenery, and only 300 metres (980 ft) across at its narrowest point. The Nærøyfjord is a UNESCO World Heritage Site. From the village of Flåm, the Flåm Railway climbs 864 metres (2,835 ft) up to Myrdal Station in a distance of only 20 kilometres (12 mi)—the steepest unassisted railway climb in the world.
The Sognefjord Span (power lines) crosses the fjord with a span of 4,597 metres (15,082 ft). This is the second largest span of power lines in the world. The fjord has become a tourist attraction with summer tourists being an important part of the local economy.
- On 24 November 1972, the submarine KNM Sklinna of the Royal Norwegian Navy had "contact" with what they presumed was a Whiskey-class submarine, after 14 days of "hunt" in the Sognefjorden. Newly released military documents confirms this episode.
