U-shaped valleys , also called trough valleys or glacial troughs , are formed by the process of glaciation . They are characteristic of mountain glaciation in particular. They have a characteristic U shape in cross-section, with steep, straight sides and a flat or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in cross-section). Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice, called glacial till or glacial erratic .

37-604: Appersett is a hamlet in the Yorkshire Dales in the Richmondshire district of North Yorkshire , England one mile (1.6 km) west of Hawes . It lies on the A684 road and an unclassified road runs alongside Widdale Beck to connect with the B6255 road between Hawes and Ingleton . The name Appersett derives from Norse and means the ' Shieling by the apple tree'. The suffix "sett",

74-691: A U-shaped valley extends into saltwater, becoming an inlet of the sea, it is called a fjord , from the Norwegian word for these features that are common in Norway. Outside of Norway, a classic U-shaped valley that is also a fjord is the Western Brook Pond Fjord in Gros Morne National Park in Newfoundland , Canada. Formation of a U-shaped valley happens over geologic time , meaning not during

111-407: A U-shaped, glaciated valley is often stepwise where flat basins are interrupted by thresholds. Rivers often dig a V-shaped valley or gorge through the threshold. Surrounding smaller tributary valleys will often join the main valleys during glaciation periods, leaving behind features known as hanging valleys high in the trough walls after the ice melts. After deglaciation, snow and ice melt from

148-440: A glacier moves downhill through a valley, usually with a stream running through it, the shape of the valley is transformed. As the ice melts and retreats, the valley is left with very steep sides and a wide, flat floor. This parabolic shape is caused by glacial erosion removing the contact surfaces with greatest resistance to flow, and the resulting section minimises friction. There are two main variations of this U-shape. The first

185-405: A human's lifespan. It can take anywhere between 10,000 and 100,000 years for a V-shaped valley to be carved into a U-shaped valley. These valleys can be several thousand feet deep and tens of miles long. Glaciers will spread out evenly in open areas, but tend to carve deep into the ground when confined to a valley. Ice thickness is a major contributing factor to valley depth and carving rates. As

222-525: A low point in the Wensleydale valley at the northern end of Widdale , where Widdale Beck flows into the River Ure. The hamlet consists of only 23 dwellings and is located on the south side of the River Ure. Up until the early part of the twentieth century, the hamlet had its own Wesleyan chapel. There are no amenities in the village, aside from an art gallery which previews the work of a local artist; however,

259-676: A major area for caving in the UK. The word dale , like dell , is derived from the Old English word dæl . It has cognates in the Nordic / Germanic words for valley ( dal , tal ), 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 (e.g., Arkengarthdale , formed by Arkle Beck ). The best-known exception

296-599: A mobile-device software app for those who wish to explore the relevant areas. 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

333-595: 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. Most of the dales contain rivers, and the area contains seven primary catchments : the Swale , Ure , Wharfe , Aire , Nidd , Ribble , and Lune . There are several notable cave systems in

370-543: 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 "(name of river)+ dale "—but only the more northern valleys (and only the upper, rural, reaches) are included in the term "The Dales". The Yorkshire Dales are surrounded by the North Pennines and Orton Fells in

407-539: Is called the Rocky Mountain model and it is attributed to alpine glacial valleys, showing an overall deepening effect on the valley. The second variation is referred to as the Patagonia-Antarctica model, attributed to continental ice sheets and displaying an overall widening effect on its surroundings. The floors of these glacial valleys are where the most evidence can be found regarding glaciation cycles. For

444-515: Is notable to Wensleydale ( Burtersett and Countersett ), with Appersett originally recorded as Appeltresate , which became Aperside and eventually, Appersett. Historically in the wapentake of Hang West and in the Parish of Aysgarth, the hamlet is now within the civil Parish of Hawes, where its population is recorded in the 2011 Census . The bridge in the hamlet that carries the A684 over Widdale Beck,

481-456: Is quite soft and it was unbelievable to many that it could be responsible for the severe carving of bedrock characteristic of glacial erosion. German geologist Penck and American geologist Davis were vocal supporters of this unprecedented glacial erosion. Progress was made in the 1970s and 1980s on the possible mechanisms of glacial erosion and U-shaped valleys via models proposed by various scientists. Numerical models have been created to explain

518-580: The Discover England websites, for example, were using the tagline "Discover 'All Creatures Great and Small' in Yorkshire". 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

555-724: The Lake District , Yosemite Valley , and the Rottal and Engstlige  [ de ] valleys in Switzerland . Glacial troughs also exist as submarine valleys on continental shelves, such as the Laurentian Channel . These geomorphic features significantly influence sediment distribution and biological communities through their modification of current patterns. Geologists did not always believe that glaciers were responsible for U-shaped valleys and other glacial erosional features. Ice

592-569: 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

629-555: The Principal Cordillera of the Andes, glacial valley floors may be covered by thick lava flows . A glacial trough or glaciated mountain valley often ends in an abrupt head known as the 'trough end' or 'trough head'. This may have almost sheer rock walls and spectacular waterfalls . They are believed to have been formed where a number of small glaciers merge to produce a much larger glacier. Examples include: Warnscale Bottom in

666-1015: The Scandinavian Mountains . They are found also in other major European mountains including the Carpathian Mountains , the Pyrenees , the Rila and Pirin mountains in Bulgaria , and the Scottish Highlands . A classic glacial trough is in Glacier National Park in Montana , USA in which the St. Mary River runs. Another well-known U-shaped valley is the Nant Ffrancon valley in Snowdonia , Wales . When

703-453: The Trip Advisor site include Aysgarth Falls , Malham Cove (scenic walking areas), Ingleborough (hiking trails) and Ribblehead Viaduct . The DalesBus service provides service in the Dales on certain days in summer, "including the Yorkshire Dales National Park and Nidderdale Area of Outstanding Natural Beauty". In summer, these buses supplement the other services operating year-round in

740-537: 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 4,971 miles (8,000 km) of dry-stone walling in

777-634: 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. 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 . The predominant rock

814-655: The Dales. Tourism in the region declined because of restrictions implemented in relation to the COVID-19 pandemic in 2020, and into 2021. Later in 2021, the volume of visits was expected to increase as a result of the 2020 TV series All Creatures Great and Small , largely filmed within the Dales. The first series aired in the UK in September 2020 and in the US in early 2021. One source stated that visits to Yorkshire websites had increased significantly by late September 2020. By early 2021,

851-648: 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

888-698: The Yorkshire Dales. Many upland areas consist of heather moorland, used for grouse shooting from 12 August (the Glorious Twelfth ). 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 have remained, including some field barns, though many are no longer in active use. Breeding of sheep and rearing of cattle remain 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

925-523: The area, including the longest system in the United Kingdom, the Three Counties . 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

962-517: The eastern edge also crosses an unclassified road). It was designed by J. S. Crossley, who designed most of the viaducts on the Settle and Carlisle line , and was opened in 1878 as part of the Midland Railway's branch from Garsdale (Hawes Junction) to Hawes. The line closed to passengers in 1959, with complete closure coming in 1964. It was grade II listed in 1969 and in 1992, British Rail offered

999-516: The economy. Visitors are often attracted by the hiking trails, including some that lead to waterfalls and picturesque villages and small towns. These include Kirkby Lonsdale (just outside the area), Hawes , Appletreewick , Masham , Clapham , Long Preston and Malham . The 73-mile-long (117 km) 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

1036-602: The location is a popular starting point for walks in Cotterdale and Widdale, and the hamlet is also on the Herriott Way, a 50 miles (80 km) circular walk through Swaledale and Wensleydale. To the south of the village is Appersett Viaduct, which used to carry the Northallerton to Garsdale railway line . The five-arch viaduct is 108 yards (99 m) long and is 56 feet (17 m) above Widdale Beck, which it spans (although

1073-735: The most part, the valley floor is wide and flat, but there are various glacial features that signify periods of ice transgression and regression. The valley can have various steps, known as valley steps , and over-deepenings anywhere from ten to hundreds of meters deep. These then fill in with sediments to create plains or water to create lakes, sometimes referred to as "string-of-pearl" or ribbon lakes. Such water filled U-valley basins are also known as "fjord-lakes" or "valley-lakes" (Norwegian: fjordsjø or dalsjø ). Gjende and Bandak lakes in Norway are examples of fjord -lakes. Some of these fjord-lakes are very deep for instance Mjøsa (453 meters) and Hornindalsvatnet (514 m). The longitudinal profile of

1110-488: The mountain tops can create streams and rivers in U-shaped valleys. These are referred to as misfit streams. The streams that form in hanging valleys create waterfalls that flow into the main valley branch. Glacial valleys may also have natural, often dam-like, structures within them, called moraines . They are created due to excess sediment and glacial till moved and deposited by the glacier. In volcanic mountain ranges, such as

1147-457: The north and west of the Dent Fault the hills are formed from older Silurian and Ordovician rocks. The underlying limestone in parts of the Dales has extensive cave systems, including the 54-mile-long (87 km) 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

1295-502: The viaduct for sale for only £1, but the new owners would be required to maintain the structure. It is used for abseiling by a local outdoor centre, but it does feature in the plans of a resurgent railway between Hawes and Garsdale . Yorkshire Dales The Yorkshire Dales are a series of valleys, or dales , in the Pennines , an upland range in England. They are mostly located in

1332-470: Was built in the early 18th century and was widened in 1795 by the architect, John Carr . The second bridge to the north west, is New Bridge, which spans the River Ure and was built in 1825 to allow Hawes to be connected to the Askrigg to Sedbergh Turnpike . Both bridges are now grade II listed structures. Although the hamlet is 776 feet (237 m) above sea level, it is subjected to flooding as it lies at

1369-481: 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.
