Airedale is a geographic area in Yorkshire, England, corresponding to the river valley of the River Aire (pronounced ''air''). The valley stretches from the river's origin in Aire Head Springs, Malham which is in the Yorkshire Dales, down past Skipton on to Keighley, Bingley and Shipley through to Leeds and Castleford and on to join the River Ouse at Airmyn. This valley is of great topographic significance as it provides low-altitude passes through the mid Pennines to the west coast known as the Aire Gap.〔(【引用サイトリンク】url=http://www.yorkshire-dales.com/aire-gap.html )〕 == History == The upper Aire valley was formed 12,000 years ago by a retreating glacier. A moraine formed in the Cononley area and the lake stretched as far north as Gargrave. Colonisation by man developed later on, especially during the Iron Age. The peoples that occupied the Aire Valley (and much of north eastern England) were called Brigantes by the Romans. Transport improved in the 18th and 19th centuries with the building of the Aire and Calder Navigation〔(【引用サイトリンク】url=https://canalrivertrust.org.uk/enjoy-the-waterways/canal-and-river-network/aire-and-calder-navigation-main-line )〕 and the Leeds and Liverpool Canal.〔(【引用サイトリンク】url=https://canalrivertrust.org.uk/enjoy-the-waterways/canal-and-river-network/leeds-and-liverpool-canal )〕 The railways arrived from the 1830s onwards and during the twentieth century the roads were vastly improved in the valley. 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「Airedale」の詳細全文を読む スポンサード リンク
