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.
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.
Urangsvågen-Rubbestadneset
In 1868 the first stone workers came to Rubbestadneset to take out the granite for the Skoltegrunns Pier, predecessor of the Skoltegrunns wharf in Bergen. Later granite was also taken out from the area, around Innværs Fjord and UransvågenN. The activity probably peaked around 1900, with over 40 men at work. 15 years later, it was finished.
Borgåsen
In Etne there are no less than four defensive refuges. They are all situated in strategic positions, so that they have served as places of refuge and protection for central parts of the district
Hamlagrø
The type of underlying rock can be decisive for how many different types of plants are found in an area. In the area around Hamlagrø-lake the diversity is especially obvious. The geological conditions change much here within a short distance.
Nordheim
"And here these endless kingdoms and these toils for a rich working life far and wide have lain and slept for a hundred thousand years! Right up until the Voss Railway came in 1883 and woke them, like the prince in the fairytale who awakened the Sleeping Beauty."
