Stetind represents a part of Norway's
so called highland plateau.
This was presumably the surface in which the rivers were carving out
before the ice ages. The glaciers later dug out these rivers further
and formed deep valleys and fjords. Mt. Stetind has been a nunatak
during parts of the ice ages, a sharp peak sticking up from the ice.
Mt. Stetind was either a part of or
right below the land plateau in Norway before the ice ages. This
plateau might have existed since the era of the dinosaurs.
The granite around Mt. Stetind is ca.
1800 million years old. Granite is a magmatic mineral. It consists of
magma that solidified deep underneath the earth crust.

Tromsø has created an animation showing how Mt. Stetind was formed
