Ølve- Mining
All in all there are ten known copper mines and two iron mines on the Ølve peninsula. Geologically, the nine mines on Varaldsøy Island also should be figured in. The industry began at Lilledal in 1642 wth the mining of iron ore. From Jernsmauget by Dyråsen, the iron ore was sent to the iron works in eastern Norway.

Hereiane
At Hereiane on warm summer days one you can walk barefoot up the hill from the fjord all the way up to 400 metres elevation. The naked, furrowed bedrock often causes travellers who see it from the north side of the fjord to wonder. Why does it look like this, and why is there so little that grows here? It is a long way to the heavy metal industry in Ålvik and Odda, and there hasn’t been a forest fire in modern times.

Lussand- geology
Hardangerfjorden kløyver Hordaland i to. Den etter måten rettlinja fjorden skjer seg liksom på skeive inn i landet. Ikkje som Sognefjorden og Nordfjord – dei krokar og buktar seg innover meir eller mindre vinkelrett på kysten. Hardangerfjordens utforming har røter 400 millionar år tilbake i tida, då den veike sona i fjellet, der isen seinare tok grådig for seg, vart danna. Denne sona stig på land ved Lussand.

Nedre Folkedal
For many years the Folkedal scythe had a good reputation. Immediately above the highway through Folkedal there is a long brick building, on the inner side of the river. Here production of scythes went on to the beginning of the 1950s.
