Editing Mousa (section)

==Geography==
Mousa lies directly on the [[60th parallel north|60th parallel]], 60 degrees north of the equator and 30 degrees south of the [[North Pole]]. It lies {{convert|1|nmi|km|0|abbr=off|spell=in}} off the east coast of [[Mainland Shetland]] in the parish of [[Dunrossness]] about {{convert|15|nmi|km|abbr=off}} south of Lerwick. Almost divided in two by inlets, East and West Hams, the island is {{convert|1+1/2|mi|km|abbr=off|round=0.5}} long and almost {{convert|1|mi|km||round=0.5|abbr=off|spell=in}} in maximum width. Geologically beds of hard sandstone alternate with muddy limestones that weather to produce fertile soil. A [[quarry]] provided [[flagstone]]s for [[Lerwick]].<ref name=Smith/>

The [[Norsemen|Norse]] tended to consider an island to be something that they could circumnavigate, and this included being able to drag a boat over land. Thus Mousa was considered two islands, namely North Isle and South Isle.
