. Housay has the most complex geology of the Out Skerries, with
granite in
Mio Ness in the far south west,
limestone on the south coast, and large concentrations of
gneiss and
schist. The island of Housay consists of several thin headlands, with the biggest pointing to the south west, and over long. To the north, another headland extends, and then turns towards the south west, running parallel to the biggest one, and separated by West Voe. The island is surrounded by a number of stacks including the
Hevda Stacks in the north and the
Stack a Mooth and
Stack a Pillar in the south. There are also some
sea caves in the south, and
Da Steig, which connects the island to Mio Ness is a collapsed one. It is separated from
Bruray by
North Mouth and
South Mouth. The island occasionally suffers from water shortages. There is little
peat on the Out Skerries, so the residents have been granted rights to cut it on
Whalsay. ==History==
