The Begervannet is a lake about 8,5 km S of Herefoss. W and N of the lake there are several feldspar quarries, three of which have been described by Müller et al. (2006).

The northern most might geographically belong to another area/farm.
In Mindat they are grouped together for reasons of tidiness.

The coordinates are for the middle of the lake.
