Mølen

Mølen is a coastal geopark in the Brunlanes area of Larvik Municipality in Vestfold county, Norway.

[1] It is a part of Vestfoldraet, the terrain left behind after the end of the most recent ice age around 10,000 years ago.

It is home to over a hundred types of rock, including Norway's national stone, Larvikite, which is named from the area.

In one of the cairns, burnt stones were found; this could be the result of a cremation dating back to the 5th century A.D.

Mølen and its bay could have been one of several transit sites in Eastern Norway, with goods from here being exchanged and conveyed to the surrounding settlements.

There are traces of volcanic activity from the Brunlanes volcano on Saltstein, a southerly headland with a beach composed almost entirely of pebbles.

The long headland of Saltstein comprises alternating layers of lava and volcanic ash.

In the far west of Saltstein, there is an approximately 4-metre (13 ft) thick layer of fragments of rock of various sizes.

Later in the carbon time series, there was basaltic volcanic activity near Skien, Holmestrand, Jeløya, and on Krokskogen and Kolsås, south of Oslo.

The lava flows were similar to those on basal volcanoes such as on Iceland, Mount Etna and Hawaii.

The Brunlanes volcano has a very particular composition found today in eastern Congo near the town of Goma.

It is part of a 5,000-kilometre (3,100 mi) coastal walk in Norway, Sweden, Denmark, Germany, Netherlands, England and Scotland.
