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.
Ølve
Ølve has a special soil type. Here one finds an extra hard clay soil. This is especially noticed by those who work with excavating for building foundations and the like. Often it is necessary to use especially big digging machines and sometimes even dynamite in order to break up the compact masses. The reason for this is the growth of the glaciers toward the end of the Ice Age: The clay, that was first deposited in front of the glacier, came under great pressure when the glacier later grew and slid out over the clay.
Ulven
In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.
The village of Etne
Much of the sand and gravel that the town of Etne is built on was laid down at the end of the Ice Age and is evidence of melting glaciers and roaring meltwater rivers. The uncompacted material in the big terraces leave their unmistakeable mark on the wide elongated valleys.
Sålesnes
Jondal has one of the country’s oldest slate quarries. Roof tiles have been extracted here since the end of the 1700s, but the quarry is much older. Kvernurdi is mentioned in a diploma in 1421, when Bård Sigurdsson at Torsnes became the owner through a settlement. Already then it must have been customary to cut millstones here.
Svåsand
Down by the fjord at Svåsand, close to the main highway, there is a long row of boathouses, one of the well-preserved, older boathouse locations along the Hardanger fjord. It is the farms at Svåsand that have their boathouses here, four main farms with origins far back in time.
