Eldsfjellet
The eclogites in western Norway were formed when Precambrian basement rocks were squeezed and pressed down under great pressure deep under the Caledonian mountain chain. The process may well have triggered some of the deepest earthquakes the world has ever known. The clearest traces of this drama are found in and around Mt. Eldsfjellet, in peaceful Meland.
Håøy
Håøy lies centrally in one of the main shipping lanes going into Bergen --- with Håyøsund on the south side facing Meland, and Hagelsundet facing Lindåslandet. Names like Nordfarskista and Nordfarsskorane explain things. The strategic position was important in Viking times and it has been important in our days too. The beacon on Håøy can have been built in the establishment of the coastal administration in Håkon the Good’s time, about 950 AD. The defence structure of which we say remains on Håøy Summit held a critical position during Norwegian neutrality during the First World War. The defence structure was taken down in 1957.
Litlandsvatnet
Large quantities of nickel ore have been mined from Litlandsvatnet, between Lonevågen and Hosanger. The discovery was made in 1875. During the period of operation from 1882 to 1945, 4170 tonnes of pure nickel were extracted from 462 000 tonnes of ore, a large production by Norwegian standards.
Manger
Mangerite is a rock type that was first made famous in a treatise by the Bergen geologist Carl Fredrik Kolderup in 1903. The rock type got its name from the place where it was found, and has made the Mangerud name well known around the world, at least among geologists.
Vågenes
On Vågenes, on one of the prominences out toward Eitrevågen, one finds garnets in anorthosite. The garnets are both older, and not least bigger, than average.
Bergsdalen
The mountains of western Norway are lovely to wander in. In Cambro-Silurian time it was the mountain itself that wandered. The mountain, or more correctly the bedrock, first moved eastward, then back a bit westward again. All this rocking back and forth in the mountains ended about 400 million years ago.
Siggjo
Siggjo is a cone-shaped, volcano-like mountaintop in the part of Hordaland where one finds the best preserved volcanic rocks. The rock types originate from one or several volcanoes that spewed out glowing lava and ash. But, the shape of the mountain, as it appears today, formed later and by completely different forces.
