Golta- Gneiss
Over thousands of years, autumn storms and strong land-driving winds have cleaned the bare rocks of Golta. The waves can beat far in over land and make it dangerous to walk along the shoreline. When the storms have calmed, the results of their work comes into view.

Spildepollen
The oceanic crust of the North Sea was subjected to a lot of stretching both in Permian and Triassic times, and later in the Jurassic. This stretching resulted in the North Sea collapsing in and also to large faults forming west of Hordaland and on the mainland. Austefjorden in Sund follows one of these faults.

Sandviksfjellet
On Sandviksfjellet there are old boulders that have been made into mountains. The stones have been stretched out or squeezed together between huge slabs of rock, during slow, but powerfulprocesses of transport. This conglomerate shows, in quite a special way, the enormous powers that were active during the collision between Norway and Greenland over 400 million years ago.
