Hutton Roof Crags is a hill in south-eastern Cumbria in north-west England, located near to the village of Hutton Roof. It has extensive areas of limestone pavement as well as grassland and woodland. The hill forms the Hutton Roof Crags Site of Special Scientific Interest and is part of the Morecambe Bay Pavements Special Area of Conservation. A significant proportion of the UK's 20 km² of limestone pavement is to be found on Hutton Roof Crags and the neighbouring Farleton Knott. Although part of the hill is grass grazed by sheep, and part is forested, much remains open common land, and it is here that most of the limestone pavement is to be found. However, much has been removed over the years for many purposes including building, agricultural fertiliser, and production of millstones, but is now protected by law and it is an offence to remove any. The limestone is over 300 metres thick, and was laid down during the Carboniferous period some 350 million years ago. The limestone pavements here occupy an intermediate position between the low-lying pavements of Gait Barrows some 8 km to the west, and those on Ingleborough, 19 km to the east. Hutton Roof National Nature Reserve is managed by the Cumbria Wildlife Trust,〔(Hutton Roof NNR ), Natural England.〕 which leases Park Wood and Hutton Roof Common from Natural England and Hutton Roof Parish Council respectively.〔(Hutton Roof Crags ), Cumbria Wildlife Trust.〕 Plants including rigid buckler fern, angular Solomon's seal, limestone fern, and dark red helleborine are to be found on the pavement. The nationally scarce rigid buckler-fern ''Dryopteris submontana'' is abundant on Hutton Roof Crags. Blue moor grass is also nationally scarce but abundant here. The name Hutton Roof Crags is believed to derive from the Old English language, and means "crags on hill near farmstead of Rolf". Access is possible via the public footpath running across the north of the fell, but is probably easier through the woods to the south-west. The extensive low limestone outcrops make the Hutton Roof Crags a popular site for bouldering.〔(), UK Climbing Logbook.〕 == References == 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「Hutton Roof Crags」の詳細全文を読む スポンサード リンク
