Quartz crystal occurrence on private land, permission to collect must be obtained from the landowner.
The locality is known since the World War 1, and was claimed by Mr. H.G. Andersen in 1985.

The locality has often been referred to as Glassberget, Ørsdalen. This is not entirely correct, as the locality lies in the neighboring Austdalen.
