Swaledale is one of the northernmost dales (valleys) in Yorkshire Dales National Park, located in northern England. It is the dale of the River Swale on the east side of the Pennines in North Yorkshire. Geographical overview Swaledale runs broadly from west to east, from the high moors on the Cumbria–Yorkshire boundary at the watershed of Northern England to the market town of Richmond, where the dale meets the lowlands. Nine Standards Rigg, the prominent ridge with nine ancient tall cairns, rises on the watershed at the head of Swaledale. To the south and east of the ridge a number of smaller dales (Birkdale, Little Sleddale, Great Sleddale and Whitsundale) join to form the narrow valley of upper Swaledale at the small village of Keld. From there, the valley runs briefly south then turns east at Thwaite to broaden progressively as it passes Muker, Gunnerside, Low Row, Healaugh and Reeth. The Pennine valley ends at Richmond, where an important medieval castle still watches the important ford from the top of a cliff. Below Richmond, the valley sides flatten out and the Swale flows across lowland farmland to meet the Ure just east of Boroughbridge at a point known as Swale Nab. The Ure becomes the Ouse, and eventually (on merging with the Trent) the Humber. From the north, Arkengarthdale and its river the Arkle Beck join Swaledale at Reeth. To the south, Wensleydale, home of the famous Wensleydale cheese, runs parallel with Swaledale. The two dales are separated by a ridge including Great Shunner Fell, and joined by the road over Buttertubs Pass. Physical character Swaledale is a typical limestone Yorkshire dale, with its narrow valley-bottom road, green meadows and fellside fields, white sheep and dry stone walls on the glacier-formed valley sides, and darker moorland skyline. The upper parts of the dale are particularly striking because of its large old limestone field barns and its profusion of wild flowers. The latter are thanks to the return to the practice of leaving the cutting of grass for hay or silage until wild plants have had a chance to seed. Occasionally visible from the valley bottom road are the slowly fading fellside scars of the 18th and 19th century lead mining industry. Ruined stone mine buildings remain, taking on the same colours as the landscape into which they are crumbling. In 1989 Swaledale (and Arkengarthdale) were designated as a Barns and
