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.
For generations the land-seine was the most important tool for catching herring and mackerel, and therefore a suitable casting bay was worth its weight in gold. Goltasundet (the Golta sound) on Golta was such a place. Here the herring often drifted in and fantastic casts might be made here.
Kval i våg! Når det ropet gjekk, var det berre å få ut den kraftige kvalnota til å stengja vågen med, og så kunne veidinga ta til. I uminnelege tider har det vore drive kvalveiding i Skogsvågen.
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.
At the southern end of the bridge between Radøy and Fosnøy archaeologists found an unusual Stone Age settlement. There was a thick “cultural layer” here with the remains of the waste dumps of a hunting people. The place was called Kotedalen. Here they came, one group after the other, and settled for some weeks, some months, or maybe years before they went on, leaving the settlement deserted. Time after time it happened. At least 16 settlement phases have been identified, stretching over 5,500 years.
