A dale is an open valley. Dale is a synonym to the word valley, which entered the English language after the Norman Conquest. Norwegian towns frequently use this term: dalekvam, so dale. The name is used when describing the physical geography of an area. It is used most frequently in the Lowlands of Scotland and in the North of England, where the term "fell" commonly refers to the mountains or hills that flank the dale.
