GEO. virtual field trip

 

Looking north and westwards from the top of Úlfarsfell towards Esja (near) and Akrafjall (distant). The age of the rocks increases steadily towards the northwest, since they have drifted to their present positions from the active Reykjanes volcanic zone (Western Volcanic Zone). The low land near sea level is part of the strandflat, formed by glacial and marine erosion. At the marine maximum approx. 11,000 years ago, the sea level lay close to the foot of the cliffs.
