The main settlement on the island today is Biggings, which overlooks Housa Voe and is surrounded by in-bye land to the east of the hill dyke (which runs south from West Voe). To the west the island is bisected by a belt of glacial moraine about one and a half kilometres in length. Much of the rest of the area consists of a shallow stony soil that may be derived from glacial till. There is an almost complete absence of peat on the island and due to the volcanic rocks the soils are relatively fertile. The lack of peat led to 'turf scalping' for fuel and the bare areas of rock in the interior.
