Aurlandsdalen
Aurlandsdalen is a glacially-formed Norwegian valley that is about 40 kilometres (25 mi) in length (Geiteryggen-Vassbygdi). The valley is situated in Aurland Municipality in Vestland county, to the south of the Sognefjorden. One of the best-known tourist tracks in Norway follows the valley from Geiteryggen just across the border of Hol Municipality and north east to Aurlandsvangen at the Aurlandsfjorden in Sogn. The valley narrows and becomes a tight, dramatic Western Norway valley. It combines glacially carved valleys with diverse plant species, and a number of cultural monuments in the form of old farms and mountain dairy farms (regionally called "støl"s) to form a recognized tourist attraction. The richness in plant species is due to both the soil, rich in minerals formed from phyllite in the rocks and cultural influence through the centuries.
The upper part of the river running through the valley is called Stemberdøla; in the lower part it is called Aurlandselvi. The route from Aurland to Hol has been the shortest connection between western and eastern Norway since prehistoric times. Thus the valley has been an important connection line for commercial journeys and cattle drives through and along the valley and over the surrounding mountain highlands.
Aurlandsdalen can be reached either from the village of Aurlandsvangen or from Vierbotn at Geiteryggen (which transliterates, perhaps descriptively, as goat's back). Access to Aurlandsvangen is possible via hurtigbåt (rapid boat) from Bergen or via the European route E16 highway. Geiteryggen can be reached via highway 50 from Hol Municipality in Hallingdal.
The ancient passage through the mountains can be traveled on foot via Norwegian Mountain Touring Association (DNT) marked tracks: Finse - Geiteryggen, Raggsteindalen (at Strandafjorden) - Geiteryggen or the track Iungsdalen - Stemberdalen. Another DNT track leads from Hallingskeid through Såtedalen, along north west side of Omnsvatnet and further over Bakkahelleren along Geiteryggvatnet to Geiteryggen.
The original proposal for routing the Bergen Line had it passing through Geiteryggen; if these plans had been carried out the railway tracks would have followed this trace to Hallingskeid.
Down the long valley, descending from the open mountain highland at Geiteryggen (1,232 m in elevation) the landscape becomes gradually more broken. At Stemberdalen, (also called Steinbergdalen, Stemmerdalen, Stodmerrdalen) at about 1100 m in elevation, the valley is wide and open with gradual mountains slopes and open areas covered with farm places. Earlier, before dams pooled the river into reservoirs, the river flowed gradually in broad turns which could be navigated by small boats. From Stemberdalen the valley again narrows with the hillsides steepening and the river channel increasing in gradient.
At Østerbø (Øvstebø, Aurdal), at about 900 metres (3,000 ft), for a limited stretch the timberline reaches up to the middle of the hillsides. The river widens to a calm lake, Aurdalsvatnet, which is now regulated for hydroelectric power generation. From Østerbø the valley becomes steeper and more narrow as it passes downwards to Vassbygdi (vass = water, bygd = settlement, parish). The mountain flanks rise steeply from the bottom of the valley. The river has cut deep gorges, where it is diverted to the south, then turning north again at Heimrebø, until it resumes it original course to the northwest. From here the river follows a gorge so deep that the valley bottom is impassable. At the depopulated Almen region, the valley is partly passable along the river. The valley then gradually widens until it meets Midjedalen in vassbygdi. From here to Aurlandsvangen, the bottom of the valley is relatively flat and even and the mountain flanks ascend steeply. Access to Aurlandsvangen is cut off by Vassbygdvatnet; the road bypasses the Vassbygvatnet through a tunnel.
The Aurland river system was estimated to annually produce around 2 billion kWh of hydroelectric power. It was developed in the 1970s after a much disputed decision by the Stortinget (the Norwegian Parliament) in 1969. Oslo Lysverker (the Oslo utility) was behind this development. It was promoted as a demonstration of public power development.
