Dale (landform)
A dale is a valley, especially an open, gently-sloping ground between low hills with a stream flowing through it. It is used most frequently in the North of England and the Southern Uplands of Scotland; the term "fell" commonly refers to mountains or hills that flank a dale. As with many other words, dale was preserved by Viking influence in Northern England.
It appears in various contexts, such as up hill and down dale "over every hill and dale", and "up all hills, down all dales.
