Close to the tunnel opening at Amalie Skrams vei in Ssandviken, there is a cultural monument of European dimensions; a rope making works that produced rope and fishing tackle for West and North Norway.
Roughly 550 million years ago, what is now Finse lay at the bottom of the sea - the remains of mud and clay that were deposited in this sea have ended up on the roofs of Norway. Also the thrust sheet from the continental collision has found its way to Finse, after a several hundred kilometre-long, trek through the mountains, that took several tens of millions of years to complete.
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.
When the workers came to Kollsnes to start on the work with the landing for the gas terminal from the Troll field in the North Sea, they found the ruins of an old farm mill at Kvernapollen.
Holmengrå is the only place in Hordaland where we find traces of the abrasion that is supposed to have transformed Western Norway from a Himalaya-like high mountain landscape during the earth's Paleozoic Era, to a flat lowlands terrain during the Mezosoic Era. Just 400 million years ago, large and small stones plummeted down from the high mountains. Some of these stones became incorporated into the conglomerate bedrock on Holmengrå.
The industrial settlement Bjørsvik
If you enter the farmyard at Rekve, some kilometres from Bulken, where the road departs to Giljarhus, you no longer meet “the miller”, Knut Hernes, in his old rural mill. But some years ago he would wish you welcome, friendly and hospitable, and show you around his mill, which had been his workplace for a generation. As light-footed as a youth he climbed in steep ladders high up into the waterfall, to let the water down on to the waterwheel.
In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.
