The Yorkshire Dales are a series of valleys, or dales, in the Pennines, an upland range in England. They are mostly located in the ceremonial county of North Yorkshire, but extend into Cumbria and Lancashire; they are entirely within the historic boundaries of Yorkshire. The majority of the dales are within the Yorkshire Dales National Park, created in 1954.[1] The exception is the area around Nidderdale, which forms the separate Nidderdale Area of Outstanding Natural Beauty.
The landscape of the Yorkshire Dales consists of sheltered glacial valleys separated by exposed moorland.[2] The predominant rock is Carboniferous Limestone, which is particularly visible in the south-west in features such as Malham Cove. It is overlain in many areas by the Yoredale Series of alternating weak shales and hard limestones and sandstones, which give the dales their characteristic 'stepped' appearance.[3] Most of the dales contain rivers, and the area contains seven primary catchments: the Swale, Ure, Wharfe, Aire, Nidd, Ribble, and Lune.[4] There are several notable cave systems in the area, including the longest system in the United Kingdom, the Three Counties.[5]
Agriculture and other land management has significantly affected the appearance of the Dales, through the creation of pastures and meadows for livestock grazing and moorland for red grouse shooting. Dry stone walls and field barns are characteristic of the valley floors, particularly Wensleydale and Swaledale in the north.[2] Wensleydale cheese is a particularly famous product from the region.[2] The dales are popular for hiking, and are crossed by the Dales Way, Pennine Way, and Coast to Coast long-distance footpaths.[6][7] The Yorkshire Three Peaks is a walking trail entirely within the area which takes in its three highest mountains: Ingleborough (723 m (2,372 ft)), Whernside (736 m (2,415 ft)), and Pen-y-ghent (694 m (2,277 ft)).[8] The extensive cave systems are a major area for caving in the UK.[9]
There are over 2500 known caves in the Dales including the longest system in Britain
