69-606: Dovedale is a valley in the Peak District of England. The land is owned by the National Trust and attracts a million visitors annually. The valley was cut by the River Dove and runs for just over 3 miles (5 km) between Milldale in the north and a wooded ravine, near Thorpe Cloud and Bunster Hill, in the south. In the wooded ravine, a set of stepping stones cross the river and there are two caves known as

138-645: A transverse Mercator projection with an origin (the "true" origin) at 49° N , 2° W (an offshore point in the English Channel which lies between the island of Jersey and the French port of St. Malo ). Over the Airy ellipsoid a straight line grid, the National Grid, is placed with a new false origin to eliminate negative numbers, creating a 700 km by 1300 km grid. This false origin

207-653: A Peak District National Park survey conducted in 1986/87, more than a fifth of visitors said walking was their main reason for visiting. A footpath count on a Sunday in August 1990 recorded 4,421 walkers on the Staffordshire side of the river and 3,597 on the Derbyshire bank. Riverside paths make the valley accessible to walkers. Fishing has grown in popularity as well, due in part to associations with Izaak Walton's The Compleat Angler. Some fishing rights are held by

276-414: A broader floodplain may result. Deposition dominates over erosion. A typical river basin or drainage basin will incorporate each of these different types of valleys. Some sections of a stream or river valleys may have vertically incised their course to such an extent that the valley they occupy is best described as a gorge , ravine , or canyon . Rapid down-cutting may result from localized uplift of

345-533: A cirque glacier. During glacial periods, for example, the Pleistocene ice ages, it is in these locations that glaciers initially form and then, as the ice age proceeds, extend downhill through valleys that have previously been shaped by water rather than ice. Abrasion by rock material embedded within the moving glacial ice causes the widening and deepening of the valley to produce the characteristic U or trough shape with relatively steep, even vertical sides and

414-504: A grid index where the tens denote the progress from West to East and the units from South to North. In the north of Scotland, the numbering is modified: the 100 km square to the north of 39 is numbered N30; the square to the north of 49 is N40, etc. The grid is based on the OSGB36 datum (Ordnance Survey Great Britain 1936, based on the Airy 1830 ellipsoid ), and was introduced after

483-594: A narrow valley with steep sides. Gill is used to describe a ravine containing a mountain stream in Cumbria and the Pennines . The term combe (also encountered as coombe ) is widespread in southern England and describes a short valley set into a hillside. Other terms for small valleys such as hope, dean, slade, slack and bottom are commonly encountered in place-names in various parts of England but are no longer in general use as synonyms for valley . The term vale

552-432: A relatively flat bottom. Interlocking spurs associated with the development of river valleys are preferentially eroded to produce truncated spurs , typical of glaciated mountain landscapes. The upper end of the trough below the ice-contributing cirques may be a trough-end . Valley steps (or 'rock steps') can result from differing erosion rates due to both the nature of the bedrock (hardness and jointing for example) and

621-523: A result of bad weather, and in 2020 during the COVID-19 pandemic . Valley At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock , dry valleys may also result from drainage now taking place underground rather than at

690-465: A slower rate than that of the main valley floor; thus the difference in the two valleys' depth increases over time. The tributary valley, composed of more resistant rock, then hangs over the main valley. Trough-shaped valleys also form in regions of heavy topographic denudation . By contrast with glacial U-shaped valleys, there is less downward and sideways erosion. The severe downslope denudation results in gently sloping valley sides; their transition to

759-427: A valley between its sides is referred to as the valley floor. The valley floor is typically formed by river sediments and may have fluvial terraces . The development of a river valley is affected by the character of the bedrock over which the river or stream flows, the elevational difference between its top and bottom, and indeed the climate. Typically the flow will increase downstream and the gradient will decrease. In

828-510: A variety of transitional forms between V-, U- and plain valleys can form. The floor or bottom of these valleys can be broad or narrow, but all valleys have a shoulder. The broader a mountain valley, the lower its shoulders are located in most cases. An important exception is canyons where the shoulder almost is near the top of the valley's slope. In the Alps – e.g. the Tyrolean Inn valley –

897-405: Is a tributary valley that is higher than the main valley. They are most commonly associated with U-shaped valleys, where a tributary glacier flows into a glacier of larger volume. The main glacier erodes a deep U-shaped valley with nearly vertical sides, while the tributary glacier, with a smaller volume of ice, makes a shallower U-shaped valley. Since the surfaces of the glaciers were originally at

966-606: Is a short distance along the river from the stepping stones at Thorpe Cloud. The limestone promontory called Lover's Leap is accessible from a set of steps. The steps were built by Italian prisoners of war captured in the Second World War and are now maintained by the National Trust and the National Park Authority. At Lover's Leap , a young woman who believed her lover had been killed in

1035-467: Is an abbreviated alphanumeric reference where the letters are simply omitted, e.g. 166712 for the summit of Ben Nevis. Unlike the numeric references described above, this abbreviated grid reference is incomplete; it gives the location relative to an OS 100×100 km square, but does not specify which square. It is often used informally when the context identifies the OS 2-letter square. For example, within

1104-621: Is called the Helmert datum transformation , which results in a typical 7 m error from true. The definitive transformation from ETRS89 that is published by the Ordnance Survey is called the National Grid Transformation OSTN15. This models the detailed distortions in the 1936–1962 retriangulation, and achieves backwards compatibility in grid coordinates to sub-metre accuracy. The difference between

1173-481: Is located south-west of the Isles of Scilly. In order to minimize the overall scale error, a factor of 2499/2500 is applied. This creates two lines of longitude about 180 km east and west of the central meridian along which the local scale factor equals 1, i.e. map scale is correct. Inside these lines the local scale factor is less than 1, with a minimum of 0.04% too small at the central meridian. Outside these lines

1242-578: Is now one of the most visited natural tourist sites in Britain. In July 2014 it was announced that a hoard of Late Iron Age and Roman coins has been discovered in Reynard's Kitchen Cave. The 26 coins discovered, which have been declared as "treasure", included three Roman coins from before the Roman invasion of Britain , and gold and silver pieces of Late Iron Age date, which are believed to have come from

1311-650: Is now the preferred coordinate reference system across Ireland. ITM is based on the Universal Transverse Mercator coordinate system (UTM), used to provide grid references for worldwide locations, and this is the system commonly used for the Channel Islands . European-wide agencies also use UTM when mapping locations, or may use the Military Grid Reference System (MGRS), or variants of it. The first letter of

1380-501: Is only 50 meters (160 ft) deep while the main fjord is around 1,300 meters (4,300 ft) at the same point. Glaciated terrain is not the only site of hanging streams and valleys. Hanging valleys are also simply the product of varying rates of erosion of the main valley and the tributary valleys. The varying rates of erosion are associated with the composition of the adjacent rocks in the different valley locations. The tributary valleys are eroded and deepened by glaciers or erosion at

1449-488: Is the word cwm borrowed from Welsh . The word dale occurs widely in place names in the north of England and, to a lesser extent, in southern Scotland. As a generic name for a type of valley, the term typically refers to a wide valley, though there are many much smaller stream valleys within the Yorkshire Dales which are named "(specific name) Dale". Clough is a word in common use in northern England for

1518-629: Is used in England and Wales to describe a wide river valley, usually with a particularly wide flood plain or flat valley bottom. In Southern England, vales commonly occur between the outcrops of different relatively erosion-resistant rock formations, where less resistant rock, often claystone has been eroded. An example is the Vale of White Horse in Oxfordshire. Some of the first human complex societies originated in river valleys, such as that of

1587-580: The British Isles : this article describes the system created solely for Great Britain and its outlying islands (including the Isle of Man ). The Irish grid reference system is a similar system created by the Ordnance Survey of Ireland and the Ordnance Survey of Northern Ireland for the island of Ireland. The Irish Transverse Mercator (ITM) coordinate reference system was adopted in 2001 and

1656-573: The Corieltavi , a Celtic tribe based in the East Midlands . National Trust archaeologist Rachael Hall said: "The coins would suggest a serious amount of wealth and power of the individual who owned them." The coins were scheduled to go on display at Buxton Museum in late 2014. The River Dove is a famous trout stream, 45 miles in length. Charles Cotton 's Fishing House, the inspiration for Izaak Walton 's The Compleat Angler , stands in

1725-526: The Dove Holes . Dovedale's other attractions include rock pillars such as Ilam Rock , Viator's Bridge and the limestone features Lovers' Leap and Reynard's Cave . The limestone rock that forms the geology of Dovedale is the fossilised remains of sea creatures that lived in a shallow sea over the area during the Carboniferous period, about 350 million years ago. During the two ice ages ,

1794-698: The Latin terms for 'valley, 'gorge' and 'ditch' respectively. The German term ' rille ' or Latin term 'rima' (signifying 'cleft') is used for certain other elongate depressions on the Moon. See also: Ordnance Survey National Grid The Ordnance Survey National Grid reference system ( OSGB ), also known as British National Grid ( BNG ), is a system of geographic grid references , distinct from latitude and longitude , whereby any location in Great Britain can be described in terms of its distance from

1863-629: The Napoleonic Wars threw herself from the promontory. Her skirt caught in the branches of a tree as she fell and saved her life. When she got home, she heard her lover was alive. There are other similar legends about Lover's Leap, including one placing the story in World War II . Opposite Lover's Leap is a limestone formation called the Twelve Apostles. The rock spires have been created from hard reef limestone; they protrude from

1932-504: The Nile , Tigris-Euphrates , Indus , Ganges , Yangtze , Yellow River , Mississippi , and arguably the Amazon . In prehistory , the rivers were used as a source of fresh water and food (fish and game), as well as a place to wash and a sewer. The proximity of water moderated temperature extremes and provided a source for irrigation , stimulating the development of agriculture . Most of

2001-668: The first civilizations developed from these river valley communities. Siting of settlements within valleys is influenced by many factors, including the need to avoid flooding and the location of river crossing points. Numerous elongate depressions have been identified on the surface of Mars , Venus , the Moon , and other planets and their satellites and are known as valles (singular: 'vallis'). Deeper valleys with steeper sides (akin to canyons) on certain of these bodies are known as chasmata (singular: 'chasma'). Long narrow depressions are referred to as fossae (singular: 'fossa'). These are

2070-755: The retriangulation of 1936–1962 . It replaced the Cassini Grid which had previously been the standard projection for Ordnance Survey maps. The Airy ellipsoid is a regional best fit for Britain; more modern mapping tends to use the GRS80 ellipsoid used by the Global Positioning System (the Airy ellipsoid assumes the Earth to be about 1 km smaller in diameter than the GRS80 ellipsoid, and to be slightly less flattened). The British maps adopt

2139-577: The British National Grid is derived from a larger set of 25 squares of size 500 km by 500 km, labelled A to Z, omitting one letter (I) (refer diagram below), previously used as a military grid. Four of these largest squares contain significant land area within Great Britain: S, T, N and H. The O square contains a tiny area of North Yorkshire , Beast Cliff at OV 0000 , almost all of which lies below mean high tide. For

2208-655: The Izaak Walton Hotel (part of the Duke of Rutland 's estate at the southern end of Dovedale on the Staffordshire bank, SK143508). Increased popularity has given rise to problems of congestion and erosion. Charles Cotton 's Fishing House, the inspiration for Izaak Walton 's The Compleat Angler , stands in the woods by the River Dove. Samuel Johnson , Lord Tennyson , John Ruskin and Lord Byron all praised Dovedale's scenery. The last wrote of Dovedale to

2277-472: The National Trust. The ancient, narrow packhorse bridge at Milldale originally had no side walls so that horses with panniers could cross the bridge without being impeded. Izaak Walton , who refers to himself as "Viator", which is Latin for "traveller", wrote about it in The Compleat Angler : "What’s here, the sign of a bridge? Do you travel in wheelbarrows in this country? This bridge

2346-588: The OSGB 36 lines in South Cornwall , the difference diminishing to zero in the Scottish Borders , and then increasing to about 50 m north on the north coast of Scotland . (If the lines are further east , then the longitude value of any given point is further west . Similarly, if the lines are further south, the values will give the point a more northerly latitude.) The smallest datum shift

2415-709: The OSGB36 National Grid location for Ben Nevis is at 216600, 771200. Grid references may also be quoted as a pair of numbers: eastings then northings in metres, measured from the southwest corner of the SV square. 13 digits may be required for locations in Orkney and further north. For example, the grid reference for Sullom Voe Oil Terminal in the Shetland islands may be given as HU396753 or 439668,1175316 . Another, distinct, form of all-numeric grid reference

2484-524: The Scandinavian ice sheet during the various ice ages advanced slightly uphill against the lie of the land. As a result, its meltwaters flowed parallel to the ice margin to reach the North Sea basin, forming huge, flat valleys known as Urstromtäler . Unlike the other forms of glacial valleys, these were formed by glacial meltwaters. Depending on the topography , the rock types , and the climate ,

2553-511: The actual valley bottom is unclear. Trough-shaped valleys occur mainly in periglacial regions and in tropical regions of variable wetness. Both climates are dominated by heavy denudation. Box valleys have wide, relatively level floors and steep sides. They are common in periglacial areas and occur in mid-latitudes, but also occur in tropical and arid regions. Rift valleys, such as the Albertine Rift and Gregory Rift are formed by

2622-528: The area around 800 CE . Local place names such as Thorpe are of Scandinavian origin. These settlements became permanent, and Thorpe is mentioned in the Domesday Book of 1086. Viator's Bridge , a packhorse bridge in Milldale has been in use since the medieval period when silks and flax were transported from nearby Wetton and Alstonefield . Tourism started in the 18th century, and Dovedale

2691-433: The context of a location known to be on OS Landranger sheet 41 (which extends from NN000500 in the south-west to NN400900 in the north-east) the abbreviated grid reference 166712 is equivalent to NN166712. If working with more than one Landranger sheet, this may also be given as 41/166712. Alternatively, sometimes numbers instead of the two-letter combinations are used for the 100×100 km squares. The numbering follows

2760-570: The coordinates on different datums varies from place to place. The longitude and latitude positions on OSGB 36 are the same as for WGS 84 at a point in the Atlantic Ocean well to the west of Great Britain. In Cornwall , the WGS 84 longitude lines are about 70 metres east of their OSGB 36 equivalents, this value rising gradually to about 120 m east on the east coast of East Anglia . The WGS 84 latitude lines are about 70 m south of

2829-466: The digits is for the first coordinate and the second half for the other. The most common usage is the six figure grid reference , employing three digits in each coordinate to determine a 100 m square. For example, the grid reference of the 100 m square containing the summit of Ben Nevis is NN 166 712 . (Grid references may be written with or without spaces; e.g., also NN166712.) NN has an easting of 200 km and northing of 700 km, so

The Dovedale Dash is an annual 4 + 3 ⁄ 4 -mile (7.6 km) cross-country race along the banks of the River Dove , along Dovedale, and between the villages of Ilam and Thorpe. First organised in 1953, the race takes place on the first Sunday of November, although previously it was held on the closest Sunday to Guy Fawkes Night . The race has been cancelled on five occasions, most recently in 1998, 2000 and 2004, as

2967-560: The expansion of the Earth 's crust due to tectonic activity beneath the Earth's surface. There are many terms used for different sorts of valleys. They include: Similar geographical features such as gullies , chines , and kloofs , are not usually referred to as valleys. The terms corrie , glen , and strath are all Anglicisations of Gaelic terms and are commonly encountered in place-names in Scotland and other areas where Gaelic

3036-443: The flow slower and both erosion and deposition may take place. More lateral erosion takes place in the middle section of a river's course, as strong currents on the outside of its curve erode the bank. Conversely, deposition may take place on the inside of curves where the current is much slacker, the process leading to the river assuming a meandering character. In the lower valley, gradients are lowest, meanders may be much broader and

3105-427: The land surface or rejuvenation of the watercourse as a result for example of a reduction in the base level to which the river is eroded, e.g. lowered global sea level during an ice age . Such rejuvenation may also result in the production of river terraces . There are various forms of valleys associated with glaciation. True glacial valleys are those that have been cut by a glacier which may or may not still occupy

3174-529: The limestone rock (known as reef limestone) was cut into craggy shapes by glacial meltwater, and dry caves such as Dove Holes and Reynard's Kitchen Cave were eventually formed. The caves were used as shelters by hunters around 13,000 BCE , and Dovedale has seen continuous human activity since. Around 4,500 years ago Neolithic farmers used the caves as tombs. There is evidence from Reynard's Cave of Bronze Age activity, and artifacts found there are displayed at Buxton Museum and Art Gallery . Vikings settled in

3243-473: The local scale factor is greater than 1, and is about 0.04% too large near the east and west coasts. Grid north and true north are only aligned on the central meridian (400 km easting) of the grid which is 2° W (OSGB36) and approx. 2° 0′ 5″ W ( WGS 84 ). A geodetic transformation between OSGB 36 and other terrestrial reference systems (like ITRF2000 , ETRS89 , or WGS 84 ) can become quite tedious if attempted manually. The most common transformation

3312-463: The ocean or perhaps an internal drainage basin . In polar areas and at high altitudes, valleys may be eroded by glaciers ; these typically have a U-shaped profile in cross-section, in contrast to river valleys, which tend to have a V-shaped profile. Other valleys may arise principally through tectonic processes such as rifting . All three processes can contribute to the development of a valley over geological time. The flat (or relatively flat) portion of

3381-528: The opposite bank, at grid reference SK141516 , is the higher but less isolated Bunster Hill, 1,079 ft (329 m), which is also a reef knoll. They were acquired by the National Trust in 1934 for the South Peak Estate. Milldale is a village of stone cottages at the northern end of Dovedale and the main access point to the dale from the north. A corn mill stood here until the mid-19th century; its stables are now used as an information hut by

3450-572: The origin (0, 0), which lies to the west of the Isles of Scilly . The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in its survey data, and in maps based on those surveys, whether published by the Ordnance Survey or by commercial map producers. Grid references are also commonly quoted in other publications and data sources, such as guide books and government planning documents. A number of different systems exist that can provide grid references for locations within

3519-552: The poet Thomas Moore , "I can assure you there are things in Derbyshire as noble as Greece or Switzerland." Elizabeth Bennet and Mr Darcy talk about her travels in Derbyshire, including Dove Dale, after they meet unexpectedly at Pemberley in Jane Austen 's Pride and Prejudice . Dovedale was featured on the 2005 BBC TV programme Seven Natural Wonders as one of the wonders of the Midlands. The stepping stones across

3588-436: The power of the moving ice. In places, a rock basin may be excavated which may later be filled with water to form a ribbon lake or else by sediments. Such features are found in coastal areas as fjords . The shape of the valley which results from all of these influences may only become visible upon the recession of the glacier that forms it. A river or stream may remain in the valley; if it is smaller than one would expect given

3657-708: The river figure prominently in Jorge Grau's 1974 film The Living Dead at the Manchester Morgue . The area along the river was used in Franco Zeffirelli 's 1996 version and the BBC's 2006 version of Jane Eyre , and Dovedale also featured in the 2008 film The Other Boleyn Girl . The Ridley Scott film Robin Hood also used Dovedale as a location, and it can be clearly seen in several scenes towards

3726-446: The same elevation , the shallower valley appears to be 'hanging' above the main valley. Often, waterfalls form at or near the outlet of the upper valley. Hanging valleys also occur in fjord systems underwater. The branches of Sognefjord are much shallower than the main fjord. The mouth of Fjærlandsfjord is about 400 meters (1,300 ft) deep while the main fjord nearby is 1,200 meters (3,900 ft) deep. The mouth of Ikjefjord

3795-440: The second letter, each 500 km square is subdivided into 25 squares of size 100 km by 100 km, each with a letter code from A to Z (again omitting I) starting with A in the north-west corner to Z in the south-east corner. These squares are outlined in light grey on the "100km squares" map, with those containing land lettered. The central (2° W) meridian is shown in red. Within each square, eastings and northings from

3864-550: The shoulders are quite low (100–200 meters above the bottom). Many villages are located here (esp. on the sunny side) because the climate is very mild: even in winter when the valley's floor is filled with fog, these villages are in sunshine . In some stress-tectonic regions of the Rocky Mountains or the Alps (e.g. Salzburg ), the side valleys are parallel to each other, and are hanging . Smaller streams flow into rivers as deep canyons or waterfalls . A hanging valley

3933-849: The size of its valley, it can be considered an example of a misfit stream . Other interesting glacially carved valleys include: A tunnel valley is a large, long, U-shaped valley originally cut under the glacial ice near the margin of continental ice sheets such as that now covering Antarctica and formerly covering portions of all continents during past glacial ages. Such valleys can be up to 100 km (62 mi) long, 4 km (2.5 mi) wide, and 400 m (1,300 ft) deep (its depth may vary along its length). Tunnel valleys were formed by subglacial water erosion . They once served as subglacial drainage pathways carrying large volumes of meltwater. Their cross-sections exhibit steep-sided flanks similar to fjord walls, and their flat bottoms are typical of subglacial glacial erosion. In northern Central Europe,

4002-412: The south west corner of the square are given numerically. For example, NH0325 means a 1 km square whose south-west corner is 3 km east and 25 km north from the south-west corner of square NH. A location can be indicated to varying resolutions numerically, usually from two digits in each coordinate (for a 1 km square) through to five (for a 1 m square); in each case the first half of

4071-549: The stones with layers of mortar and limestone slabs. At the southern end of Dovedale, at grid reference SK151510 between the villages of Thorpe and Ilam , stands Thorpe Cloud, 942 ft (287 m), an isolated limestone hill known as a reef knoll . It provides a viewpoint north up the dale and south across the Midlands plain. Its name "cloud" is a derivation of the Old English word clud which means "hill". On

4140-520: The surface. Rift valleys arise principally from earth movements , rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. Valleys may arise through several different processes. Most commonly, they arise from erosion over long periods by moving water and are known as river valleys. Typically small valleys containing streams feed into larger valleys which in turn feed into larger valleys again, eventually reaching

4209-407: The upper valley, the stream will most effectively erode its bed through corrasion to produce a steep-sided V-shaped valley. The presence of more resistant rock bands, of geological faults , fractures , and folds may determine the course of the stream and result in a twisting course with interlocking spurs . In the middle valley, as numerous streams have coalesced, the valley is typically wider,

4278-407: The valley at the present day. Such valleys may also be known as glacial troughs. They typically have a U-shaped cross-section and are characteristic landforms of mountain areas where glaciation has occurred or continues to take place. The uppermost part of a glacial valley frequently consists of one or more 'armchair-shaped' hollows, or ' cirques ', excavated by the rotational movement downslope of

4347-539: The valley side, and the river has eroded the rock and soil around them. The National Trust clears plant life to ensure the rock formations are visible. Dovedale is of special ecological interest for its plant life, particularly the calcareous ash woods, which are considered among the best in England. There are unusual plants such as Solomon's seal , lily of the valley , herb-paris and small and large-leaved lime trees. Birds found here include common kingfisher , grey heron and dipper . Gentry comprised most of

4416-556: The visitors to Dovedale during the 18th and 19th centuries. From 1899 the Ashbourne-Buxton railway line ran to Thorpe Cloud station , above the village of Thorpe, making Dovedale more widely accessible to walkers and hikers of all social classes. Improvements in road transport facilitated travel to the area as well. In 1931 Ramsay MacDonald 's Labour government recommended creating a ‘National Park Authority’ to select natural areas for designation as national parks. Dovedale

4485-552: The woods by the river. From Hartington to its confluence with the River Manifold at Ilam the River Dove flows through the scenic limestone valley known as Dove Valley, or Dovedale. From Hartington south to Ilam, a distance of eight miles (13 km), the Dove flows through Beresford Dale, Wolfscote Dale, Milldale, and then Dovedale. Much of the dale is in the ownership of the National Trust's South Peak Estate . Dovedale

4554-483: Was acquired in 1934, with successive properties added until 1938, and Wolfscote Dale in 1948. Dovedale became a National Nature Reserve in 2006 in recognition that it is "one of England's finest wildlife sites" with diverse plant life and interesting rock formations. The National Trust became embroiled in controversy in 2010, when in conjunction with Derbyshire County Council it oversaw the renovation of Dovedale's iconic stepping stones. It involved topping all but one of

4623-442: Was made for nothing else – why a mouse can hardly go over it, tis not two fingers broad!" From this the bridge acquired the name Viator's Bridge. The bridge has been in use since the medieval period, for packhorses transporting silks and flax from nearby Wetton and Alstonefield . It is listed as an ancient monument . Dovedale is notable for its numerous limestone formations. The most southerly named formation, Dovedale Castle,

4692-414: Was once widespread. Strath signifies a wide valley between hills, the floor of which is either level or slopes gently. A glen is a river valley which is steeper and narrower than a strath. A corrie is a basin-shaped hollow in a mountain. Each of these terms also occurs in parts of the world formerly colonized by Britain . Corrie is used more widely by geographers as a synonym for (glacial) cirque , as

4761-560: Was one of the areas selected, and it was eventually included within the Peak District National Park when it became Britain's first National Park in 1951. In July 1937, Staffordshire County Council converted the Leek and Manifold Valley Light Railway into a tarmac path now known as Manifold Way . The Ashbourne-Buxton railway line closed in the mid-1960s and was converted into a track known as Tissington Trail . In
