Natural factors


The walk along the trail between Sörfjorden and Àhkájávrre
is entirely due to land mass collision.

The mountain range was formed between 430 and 380 million years ago.

The crust consists of large plates, which slowly slid around and collided with each other, or away from each other. The formation  ’ Skoll’ are rock discs, which are usually between some tens and hundreds of meters in thickness.

The line from the Tysfjord Áhkájávrre is particularly interesting from a geological point of view. It is one of the few places where you succeed fairly accurately determine how far the rock discs were transported during the continent collision. In Sievgok (Seukok) nearest to Ritsem ‘Skoll’, were originally 580 kilometres to the west, then west of Lofoten !
The trail is mainly produced in the upper disc rock area, where there are plenty of glimmer slate with marble and granite. Especially along the first stretch of the fjord, up through birch forest and the final stage along the mountain ridge Gálavárddo are  large components of limestone bedrock.

There we find also the most species-rich vegetation.
When we start to go to the lower reaches of Áhkajávrre we come to the thinner stone disc formations with bedrock species syenite, granite and hard shale.

This mountain area consists mainly of a mountain plateau with a variation of between 400-1000 meters above sea level.
Stetind, (1391 meters) located at Stefjorden in Tysfjord municipality, was named in 2002 as Norway's national mountain. The mountain has always been a characteristic landmark for mariners along the North coast and Stetind was first ascended in1910.
