The Yorkshire Wolds are low hills in the counties of East Riding of Yorkshire and North Yorkshire in north-eastern England. The name also applies to the district in which the hills lie. On the western edge the Wolds rise to an escarpment which then drops sharply to the Vale of York. The highest point on the escarpment is Bishop Wilton Wold (also known as Garrowby Hill), which is 807 feet (246 metres) above sea level. To the north, on the other side of the Vale of Pickering, lie the North York Moors, and to the east the hills flatten into the plain of Holderness. The largest town in the Wolds is Driffield, with other places including Pocklington, Thixendale and Kilham, the original capital of the Wolds. The highest village on the Yorkshire Wolds is Fridaythorpe at 550 feet above sea level. ==Geology and Natural history== The hills are formed from chalk, and make an arc from the Humber estuary west of Hull up to the North Sea coast between Bridlington and Scarborough. Here they rise up to form cliffs, most notably at Flamborough, Bempton Cliffs and Filey; Flamborough Headland is designated a Heritage Coast. On the other side of the Humber, the chalk formations continue as the Lincolnshire Wolds; in fact, one can view the Humber as cutting through a single formation (see also Humber Gap). The Humber Bridge was built at the point due to its geological stability. Most of the area takes the form of an elevated, gently rolling plateau, cut by numerous deep, steep-sided, flat-bottomed valleys of glacial origin. The chalk formation of the hills provides exceptionally good drainage, with the result that most of these valleys are dry; indeed, surface water is quite scarce throughout the Wolds. Typically the valleys are hard to see from above, creating the visual impression that the landscape is much flatter than is actually the case. The unusual topography results in an "upside-down" farming system – livestock (mostly sheep and cows) graze the valleys, with the hills above used for crops. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yorkshire Wolds」の詳細全文を読む スポンサード リンク
