Island 283 - Eilean Dubh, Loch Eriboll, Highland

Eilean Dubh is a small uninhabited tidal island located on the west coast of Loch Eriboll 500 metres to the south of the island of A' chleit.  It is about 800 metres long by 400 metres wide, 10 metres above sea level at its highest point and it is covered in heather and rough grass.  It is only cut off for a short while at high tide.  It was unclear from the Ordnance Survey map whether it ever gets completely cut off but there were small amounts of loose seaweed strewn across the whole of the rocky causeway, which indicated to me that it is sometimes cut off.

The geology map shows that the eastern side of the island is composed of pipe rock while the west is composed of false bedded quartzite.  Both rocks are members of the Eriboll Sandstone Formation and were formed in the Cambrian Period.
