Coledale Valley is a narrow u-shaped valley located in the north part of the Lake District, in Cumbria, England. It runs north east toward the Derwent Valley foodplain and the village of Braithwaite. At the top of it a big rock formation can be found, named Force Crag. It is enclosed by ridges, popular with visitors. Some of the peaks are Grisedale Pike, Coledale Hause, Crag Hill, Hopegill Head. The most significant characterist is definitely Force Crag Mine, which in the Second World War was used for making munitions, by extracting barites.
