A feldspar quarry (originally a test pit) worked in a granite pegmatite dike located near the Eptevann farm, about 50 m W of the main road. The quarry was originally operated for thortveitite, which is said to have been abundant.

Stensrud (2009) writes that this was probably one of the best thortveitite localities in the world.

In Bjørlykke's time, it was just a tiny quarry, but Stensrud (2009) writes that the quarry was considerably expanded in later years.

Bjørlykke locality n° 85.
