A feldspar quarry in granite pegmatite located on the hill northeast of Sønnristjern pond.
Müller et al. (2006) write:
Complexly zoned granitic pegmatite (ZoP) which forms steep-dipping lens on a ridge NE of Sønnristjern. The pegmatite which strikes NE-SW, is about 500 m long and 30 to 90 m wide (Søvegjarto 2001). It is hosted by amphibolites with foliation-parallel quartz-feldspar leucosomes. The pegmatite consists mainly of granite pegmatite with crystal sizes of 1 to 20 cm. Two separated zoned K-feldspar-rich cores occur in the SW and NE part of the pegmatite. Two large and several small quarries are situated in the pegmatite.
