The Valen Fault

The gneiss landscape west and north of Bergen viewed in profile can remind us of a saw blade of the kind that has long, slanted sides that get broken off shorter transverse sides. It has taken several hundred million years to file this saw blade, an enduring interplay between various geological processes.

Vatlestraumen

There are coal bits hidden in the sand under Vatlestraumen. These remains from a geological layer from the Jurassic Period were discovered when the undersea Bjorøy Tunnel was built in 1994. Oil- and gas reservoirs in the Troll Field in the sea west of Hordaland are from the same time. It is, nonetheless, quite surprising to find bedrock from dinosaur time inside of the outer islands of western Norway. On the Scandinavian mainland north of Denmark, there are only a very few places where one f inds rock from this time in earth history.

Much rain, a steep drop and nearness to Bergen meant that the power-making potential of the Samnanger water system was exploited early. Samnanger was thus one of the first power-producing municipalities in western Norway. With its subsequent expansion and new power stations, about 400 gigawatts of electricity per hour were produced on average each year. This is enough to meet the energy needs of 25,000 households.

Toftestallen

The large coastal waves that crash down on the islands west in the sea gather their energy from storms and winds all the way out in the North Atlantic Ocean. The most common place of origin is nonetheless the North Sea. When these waves break over the skerries and islets along the shore, or on the rocky outermost islands, their energy is released. This takes the form of turbulence in the water and sea spray up on land. Can the enormous energy contained in the waves be exploited?

Romarheimsdalen

The Bergen Arcs have an unusually sharp boundary to the bedrock in the east. Geologists think that this was caused by movements in the earth's crust during the Devonian Period. Then, the Bergen Arcs on the Lindås peninsula sank a whole 10 kilometres in relation to the Precambrian basement gneisses on the east side of Fens Fjord and Aust Fjord.

Hummelfossen

As early as 1906 the Matre and Haugsdal waterway was bought up by the businessman Blauuw from Bergen; the first “waterfall speculator” in the Matre area. He immediately resold it to Fr. Hiorth, who transferred all the rights to the company Matrefaldene in 1908. Behind A/S Matrefaldene were German interests, Badische Anilin und Sodafabrik, which wanted to start production of saltpetre fertilizer with nitrogen and electricity.
