Ham Hill is a geological Site of Special Scientific Interest (SSSI), Scheduled Ancient Monument, Iron Age hill fort, Roman site, Local Nature Reserve and country park, to the west of Yeovil in Somerset, England. The hill has given its name to the distinctive quarried hamstone and also to two nearby villages: Stoke-sub-Hamdon and Norton Sub Hamdon, whose names mean "under-Ham-hill" (where "Ham" is Old English for a small settlement). The Mendip Hills, Blackdown Hills, Quantock Hills and Dorset Downs are all visible from Ham Hill, especially from its war memorial. It is popular for picnicking, walking and mountain biking in the grassy hollows of the old quarry workings. The geology supports a wide range of fauna including mammals, birds, invertebrates, reptiles and amphibians living on lichens, fungi, ferns and flowering plants.〔 〕 == Geology == The hill is part of ridge of sandy limestone rock which is elevated above the lower lying clay vales and nearby Somerset Levels. The sedimentary rocks were laid down in the part of the early Jurassic known as the Toarcian Stage.〔 They are given their colour by the weathering of the iron content of the stone and contain fossils such as the ammonite Dumortieria moorei. The hamstone is a distinctive honey-coloured building stone which has been used in many local villages and for buildings such as Montacute House and Sherborne Abbey. Extensive old quarry workings have changed the landscape into a warren of stony ridges and grassy hollows. Quarrying has unearthed many important historical artefacts, but also destroyed much of the archaeological context. The hill is an 11.1 ha geological Site of Special Scientific Interest (SSSI), notified in 1971, due of its particular importance to geologists because of the assemblages of fossils which it contains, the sedimentary features which it displays and the way it relates to other rocks of equivalent age in the close vicinity.〔(【引用サイトリンク】 url=http://www.english-nature.org.uk/citation/citation_photo/1000144.pdf )〕 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「Ham Hill, Somerset」の詳細全文を読む スポンサード リンク
