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.
The sea keeps the bedrock in the outer skerries smooth and clean. When the bedrock is also varied and interesting, the setting is perfect for a discovery tour of these bare-faced outcrops.
“On the country of Wallestrand…the rock almost everywhere appears to be of a slate-like substance, be it at the seashore, on the farms or in their distant fields”.
