Minerals found in august 2006 at Ryggkollen during the construction of a new alignment of the E 134 highway. This locality is no longer available.
Notable nice spheres of black tourmaline (schorl ?) up to 2,3 cm in diameter were found.
During construction of a water chamber in the same area, a few samples with bavenite was found (Brænd 2026).

Some materiale from the construction of the highway E 134 was dumped in the sand quarry at Ryggkollen.
The coordinates are approximate for te area, needs to be confirmed.
