| Description |
| I sjøkanten mellom eiendommene Skår og Rossån ble det i 1890-årene og under siste verdenskrig tatt ut noe stein til brolegning og kantstein. Bruddet ligger i en forskifret gneisformasjon, og driften har pågått i et 5 m tykt belte og i en lengde på 20 m. Bruddet ligger ved foten av en steil fjellside. Bergarten lar seg spalte ned i området 1 - 4 dm. Bergarten er ikke vurdert som murestein. |
