Geological formation in Eigersund

How to get there

Follow road 44 from Egersund towards Hellvik, on the right side you can spot the serpentine two places in the lake, just before you enter into Hellvik village. You find the signboard that explains the esker phenomena in Moi  bay,  by the road just before you leave Eigersund municipality and enter into Haa municipality. We are collaborating with landowners to make it possible to access a larger part of the serpentine, that is more than 2 km long.

Geology and nature

Several thousands of years ago, Magma Geopark was covered by a thick mass of ice. When the ice started to melt, melt water formed a stream under the ice in a long, winding tunnel. The melt water carried clay, sand and blocks of rocks towards the front of the glacier. When the ice had melted away the tunnel had become filled with this material and it remained as a long, winding ridge. It soon became covered by vegetation. Such a ridge formed in a tunnel under the ice is called an esker.

The solid rock at Eige is anorthosite which was formed about 930 million years ago. The mountains to the north towards Solbjørgnipa are made of even older rocks called gneisses.

Culture and history

A legend says that once upon a time there was a vicious serpent living in the sea. It was 2 kilometers long and its body was at least 10 meters thick. One day the Midgard Serpent decided to move from the sea up to an inland lake, but unfortunately for the huge snake it met King Olav “The Giant”. The serpent and King Olav started a great battle to determine the fate of Eige. The fight continued for several days and nights until King Olav finally managed to kill the serpent in the fields at Eige. As evidence of King Olav’s victory, the body of the serpent has been transformed into the long, grassy, winding ridge that you can see here.
