Skorpo - Polished by glaciers and meltwater
There is still a lot of ore in the abandoned mines on Varaldsøy Island. If today's prices and availability of ore continue, it is doubtful whether the mines will resume operation. But, the pyrite is there, if the market should return. On Varaldsøy Island one finds at least nine mines and prospect pits, that for the most part date back to the latter part of the 1800s.
"So many and such big potholes as are found at Eikelandsosen, we don't see other places in western Norway, and as beautifully polished as the mountainside is along the river up to Koldal , one would look a long time to see anywhere else. There is much to dazzle a geologist's eyes. If only these features could bring others the same joy!"
Freezing and thawing are processes that influence plant cover, move enormous blocks, stretche long mounds of earth, break open bedrock and create patterns in stone and earth.
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.
