Located on the eastern slope of the hill Kålsåsen (Kolåsen in older literature).

Described by Bjørlykke (1934) as "a magnetite-bearing microcline-quartz pegmatite rich in intergrowths of microcline and quartz".
The lower part of the dike was intersected by a cleavelandite-quartz dike. Microlite was first found in Norway in this dike.

Bjørlykke locality n° 41.

The altitude map is inconclusive, but the given coordinates are a potential candidate.
