A feldspar quarry in a granite pegmatite dike located about 300 m E of Øvre Frigstad.

Bjørlykke locality nr 95.

The coordinates are uncertain, since the altitude map isn't indicating a convincing hole in the ground. On an aerial picture of 2007 it is possible to see clearly a 15,5 x 6,5m large surface of white pegmatitic rock.
This locality needs field confirmation.
