The Slate Islands are an island group in the Inner Hebrides, lying immediately off the west coast of Scotland, north of Jura and southwest of Oban. The main islands are Seil, Easdale, Luing, Shuna, Torsa and Belnahua. Scarba and Kerrera, which lie nearby are not usually included.[1]
The underlying geology of the islands is Dalradian slate, which was quarried widely until the mid-20th century. Quarry working began in 1630 and at the turn of the 20th century, the quarries were yielding some eight million slates every year.
The Garvellachs lie to the southwest.
