geology underfoot, culminating in an undulating upland bog held upon the sandstones and gritstones capping the northern hills. It is this layering too that is responsible for the impressive waterfalls in Wensleydale, in particular the falls on the River Ure at Aysgarth and the great cascade of Hardraw Force above Hawes.

      While geology and subterranean force may have laid the foundation for the Dales landscape, it is the natural elements that have been responsible for moulding it. And nothing has been more dramatic in its effects than the action of ice. During the last half-million years of its history, Britain has been subjected to at least three major ice ages, when vast glacial sheets many hundreds of feet thick, inexorably fanned out from the mountain areas across much of the country. Although the general topography of the area had already been set before the ice ages began, each new advance scoured the land back to the very bedrock, gouging valleys ever deeper and straightening their erratic fluvial courses.

      When the thaws came, boulder and clay debris were dumped far from their origin and unimaginable volumes of water were released. What we see today are just the finishing touches left by the latest glacial period, whose icy tendrils left these valleys 12,000 years ago.

      The legacy of the ice can be traced throughout the Dales in characteristic rounded hills, straight U-shaped valleys and the dramatic cliffs of truncated spurs. The moving ice carried boulders far from their origins and moulded underlying clay into distinctive egg-shaped hills called drumlins. With the thaw, the unstable sides of overly steep valleys slumped in landslide, and layers of boulder clay were dumped along the base of valleys allowing surface rivers to flow over limestone. Some dales were dammed with terminal moraines that held back lakes, but all but two of these – Malham Tarn and Semer Water – have subsequently silted up or drained away. The deluge of meltwater cut spectacularly narrow ravines through the rock and created majestic waterfalls. Some of these still carry water today – although mere trickles by comparison with the former torrents of their creation – and are well worth looking out for.

      Homo sapiens appeared in Europe some 40,000 years ago and, during the warm interludes between glaciation, wandered into Britain. But with each ice age driving them back south and wiping the archaeological slate almost clean, those early incursions of people and the beasts which they followed for food have left few traces. Stone Age peoples eventually returned to the Dales around 9000 years ago, small bands of hunter-gatherers eking a nomadic existence in a steadily warming climate. Although artefacts are thin on the ground, they left their mark by beginning the clearance of primeval woodland, a process which gathered momentum with the later development of agriculture and the transition to a more settled lifestyle. The many caves and crevices in the limestone hills served as shelters for living and burial, a fact which perhaps explains the relative absence here of the constructed internment chambers, cairns and henges found elsewhere in the country. By the time of the Bronze Age, large areas had been cleared for grazing and agriculture, but a deterioration in climate led to the spread of extensive blanket bog across the upper plateaus.

      While habitation sites and field systems of earlier eras are known, their more prominent traces have been largely obliterated by later settlement, and there is little visible evidence pre-dating the Iron Age. The area fell within the territory of a British tribe known as the Brigantes, and many settlement sites and earthwork structures have been identified. Maiden Castle above Reeth and the extensive fortification surrounding the summit of Ingleborough are amongst the most spectacular examples. Although the Romans did establish a permanent fort at Bainbridge around 80AD, they never really subjugated the hill tribes. In fact, there appears to have been a relatively peaceful co-existence with lowland farmers, who would have found ready markets for their produce in the Roman economy until the eventual withdrawal of the occupation forces a little over three centuries later. The enigmatic patterns of those small Celtic fields still survive in several places, most notably above Malham and Grassington.

      The early years of the seventh century saw the arrival of Angle settlers, who continued a tradition of arable farming along the dales, reserving the higher, less productive ground of the valley sides for woodland and grazing. The lynchets (ridges) of their open field systems, created by ploughing with teams of oxen along the slopes of the valley side, survived through the medieval period and are still visible above Malham and around Clapham. The process of sporadic settlement continued throughout the Dark Ages as further waves of successive immigration brought the Vikings, their presence reflected in place names such as Yokenthwaite, Hawkswick, Appletreewick and indeed the word ‘dale’ itself.

      The next millennium heralded the new age of the invading Normans. After he had won the day, William the Conqueror consolidated his position by beating the northern part of his kingdom into submission with a heavy and cruel hand. The overlords ruled from peripheral fortress towns such as Skipton, Richmond and Barnard Castle, exploiting the remoter reaches of the Dales as hunting forests and establishing markets that thrived to serve the larger centres of population. During the succeeding centuries much of the region was gradually encompassed within vast monastic estates. Fountains Abbey and the priory at Bolton Abbey became the greatest landowners, but houses such as Furness on the Cumbrian coast and Bridlington far to the east also held significant tracts of land here. Under the careful administration and watchful eyes of the abbots and priors, the farms made their money from wool as well as growing a range of staple crops. The monasteries also exploited the mineral resources of the region, mining for coal, lead and other metals.

      After the Dissolution of the Monasteries in the 16th century, ownership of much of the land eventually fell to individual freeholding farmers, and by the 17th century a climate of growing personal prosperity brought a new confidence that was translated into building in stone. It is from this era that the earliest domestic buildings survive, sturdily constructed from rough stone, with dressed blocks being reserved for corners, lintels and window openings. They reflect the local geology, in limestone, gritstone and heavy roofs of stone flags. Although largely utilitarian and without ornate decoration, individualism is expressed in the carvings of dates and initials added to the lintels above doorways. Grouped in compact villages, often overlooking a green or spread as individual farms along the valley, they are one of the endearing features of the Dales countryside. Long and narrow, the farmhouses often included an attached barn or laithe for the animals and, in some areas, notably Swaledale and Wensleydale, isolated barns were built in the valley fields to store summer hay and house livestock over winter.

      The relative inaccessibility of the region protected it from the burgeoning development of the Industrial Revolution, for, even though it held abundant raw materials in stone, coal and metal ore, the difficulties of transportation often rendered large-scale growth uneconomic. Yet, despite its comparatively small scale, mining and quarrying did become important local money-making activities, sometimes worked on a part-time basis to supplement income from farming. The abandoned ruins of pit-head buildings, smelters and disused quarries are to be found scattered throughout the region, often in the most inhospitable of places.

      Veins of lead ore occur in the limestone throughout the eastern half of the Dales and have been mined sporadically since the arrival of the Romans. The industry peaked during the middle 18th and early 19th centuries, but then fell into decline because of high transport costs and competition from foreign imports. Where there is lead, there is often silver too, and the Duke of Devonshire’s Cupola Mine above Grassington produced a significant amount of silver as a by-product before it closed in 1885. In the area further west, around Malham, copper and zinc ores were also discovered, and more recently deposits of baryte and fluorspar have been worked in the Dales.

      To the north and on the high ground, the Yoredale rocks contain thin seams of coal of varying quality. These were intermittently mined from the beginning of the 14th century until the railway age, often from small workings called bell
