Yorkshire Dales


The Yorkshire Dales is an upland area of the Pennines in the historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954.
The Dales comprise river valleys and the hills rising from the Vale of York westwards to the hilltops of the Pennine watershed. In Ribblesdale, Dentdale and Garsdale, the area extends westwards across the watershed, but most of the valleys drain eastwards to the Vale of York, into the Ouse and the Humber. The extensive limestone cave systems are a major area for caving in the UK and numerous walking trails run through the hills and dales.

Etymology

The word dale, like dell, is derived from the Old English word dæl. It has cognates in the Nordic/Germanic words for valley, and occurs in valley names across Yorkshire and Northern England. Usage here may have been reinforced by Nordic languages during the time of the Danelaw.
Most of the dales are named after their river or stream. The best-known exception is Wensleydale, which is named after the small village and former market town of Wensley, rather than the River Ure, although an older name for the dale is Yoredale. River valleys all over Yorkshire are called "+dale"—but only the more northern valleys are included in the term "The Dales".

Geography

The Yorkshire Dales are surrounded by the North Pennines and Orton Fells in the north, the Vales of York and Mowbray in the east, the South Pennines in the south, and the Lake District and Howgill Fells to the west. They spread to the north from the market and spa towns of Settle, Skipton, and Harrogate in North Yorkshire, to the southern boundary in Wharfedale and Airedale. Natural England define the area as most of the Yorkshire Dales National Park with fringes of the Nidderdale AONB, but without the towns listed above apart from Settle.
The lower reaches of Airedale and Wharfedale are not usually included in the area, and Calderdale, south of Airedale and in the South Pennines, is not often considered part of the Dales even though it is a dale, is in Yorkshire, and its upper reaches are as scenic and rural as many further north. Additionally, although the National Park includes the Howgill Fells and Orton Fells, they are not usually considered part of the Dales.
Most of the larger southern dales, Ribblesdale, Malhamdale and Airedale, Wharfedale and Nidderdale, run roughly parallel from north to south. The more northerly dales, Wensleydale and Swaledale run generally from west to east. There are many other smaller or lesser known dales such as Arkengarthdale, Bishopdale, Clapdale, Coverdale, Kingsdale, Littondale, Langstrothdale, Raydale, Waldendale and the Washburn Valley whose tributary streams and rivers feed into the larger valleys, and Barbondale, Dentdale, Deepdale and Garsdale which feed west to the River Lune.
The characteristic scenery of the Dales is green upland pastures separated by dry-stone walls and grazed by sheep and cattle. A survey carried out in 1988, estimated that there were just over of dry-stone walling in the Yorkshire Dales. Many upland areas consist of heather moorland, used for grouse shooting from 12 August.

Cultural aspects

Much of the rural area is used for agriculture, with residents living in small villages and hamlets or in farmsteads. Miles of dry stone walls and much of the traditional architecture has remained, including some field barns, though many are no longer in active use. Breeding of sheep and rearing of cattle remains common. To supplement their incomes, many farmers have diversified, with some providing accommodations for tourists. A number of agricultural shows are held each year.
Lead mining was common in some areas of the Dales in the 19th century, particularly during 1821 to 1861, and some industrial remains can still be found, such as the Grassington miners’ cottages. Certain former mining sites are maintained by Historic England. The Grassington Moor Lead Mining Trail, with its many remaining structures, has received funding from a variety of sources. The Yorkshire Dales National Park Authority provides an app for those who wish to explore the relevant areas.

Tourism

In this primarily agricultural area, tourism has become an important contributor to the economy. In 2016, there were 3.8 million visits to the Yorkshire Dales National Park including 0.48 million who stayed at least one night. The park authority estimates that this contributed £252 million to the economy and provided 3,583 full-time equivalent jobs. The wider Yorkshire Dales area received 9.7 million visitors who contributed £644 million to the economy.
Visitors are often attracted by the hiking trails, including some that lead to beautiful waterfalls and by the picturesque villages and small towns. These include Kirkby Lonsdale, Hawes, Appletreewick, Masham, Clapham, Long Preston and Malham.
The 73 mile-long Settle–Carlisle line railway, operated by Network Rail, runs through the National Park using tunnels and viaducts, including Ribblehead.
The top-rated attractions according to travellers using the Trip Advisor site include Aysgarth Falls, Malham Cove, Ingleborough and Ribblehead Viaduct.

Geology

The dales are 'U' and 'V' shaped valleys, the former enlarged and shaped by glaciers, mainly in the most recent Devensian ice age. The underlying rock is mainly Carboniferous Limestone, which results in a large areas of karst topography, in places overlain with shale and sandstone and topped with Millstone Grit, although to the north and west of the Dent Fault the hills are formed from older Silurian and Ordovician rocks.

Cave systems

The underlying limestone in parts of the Dales has extensive cave systems, including the long Three Counties System, making it a major area for caving in the UK. There are over 2500 known caves; some are open to the public for tours. Visitors can try caving at one of the show caves: White Scar Cave, Ingleborough Cave or Stump Cross Caverns near Greenhow.
The systems include:
