A gill or ghyll is a ravine or narrow valley in the North of England and parts of Scotland. The word originates from the Old Norse gil.[1] Examples include Dufton Ghyll Wood, Dungeon Ghyll, Troller's Gill and Trow Ghyll. As a related usage, Gaping Gill is the name of a cave, not the associated stream, and Cowgill, Masongill and Halton Gill are derived names of villages.[2]
The stream flowing through a gill is often referred to as a beck: for example in Swaledale, Gunnerside Beck flows through Gunnerside Ghyll. Beck is also used as a more general term for streams in Yorkshire, Cumbria, south Durham and north Lanashire – examples include Ais Gill Beck, Arkle Beck and Peasey Beck. In the North Pennines, the word sike or syke[3] is found in similar circumstances. This is particularly common in the Appleby Fells area where sikes significantly outnumber the becks and gills; it can also be seen in the name of Eden Sike Cave in Mallerstang.
In the High Weald gills are deeply cut ravines, usually with a stream in the base[4] which eroded the ravine. These gills may be up to 200 feet (61 m) deep, which represents a significant physiographic feature in lowland England.[5]
