The Earth’s interior on the outside
400 million years ago, the oceanic crust was forced onto land where you are now standing and seeing it all as mountains and rocky terrain in hues of granite grey, red and yellow. It is no wonder that Leka was designated as Norway’s geological national monument.
What is so special about Leka?
The extremely special yellow-brown rock types on Leka’s western side long remained a mystery to researchers, but they ascertained in the 1960s that Leka has a complete section through the oceanic crust that goes all the way down to the mantle. But, how did it become this way ?
Leka’s geology – an introduction
The history of Leka’s geology began more than 500 million years ago, and includes continents colliding and an island that was tipped over on its side. Here is the short version.
Come along inside the Geology
The best way to experience Leka’s Geology is to venture out among the landscape. The tour around Leka is a nice trip by bike as well as by car, and you can make a number of exciting stops along the way:
Vandring nær strandkanten med informasjon om spennende geologiske fenomener på Leka. Følg veien ned til Våttviksletta. Herfra er løypa merket med hvite små piler, og følger svabergene rundt Våttvikodden og nordover til Vardvika. Fra Vardevika kan du følge umerket sti ved klippene videre til Bukkatalgen.
The “stone” centre at Leka Motel and Camping has an exhibition presenting the formation of Leka and its geological structure. Free admission. Gift shop selling souvenirs, jewellery, rocks, minerals and fossils from around the world.
The “Støypet” Walking Trail
Merka løype over fargerike bergarter fra havbunnskorpas dypeste del. Rullesteinstranda 90 moh (Støypet) ble brukt av steinaldermenneskene for 10.000 år siden. Steinene har fascinerende mange farger og former.
