Dunkery Beacon at the summit of Dunkery Hill is the highest point on Exmoor and in Somerset, England. It is also the highest point in southern England outside of Dartmoor. The sandstone hill rises to and provides views over the surrounding moorland, the Bristol Channel and hills up to away. The site has been visited by humans since the Bronze Age, and contains several burial mounds in the form of cairns and bowl barrows. Sweetworthy on the lower slopes is the site of two Iron Age hill forts or enclosures and a deserted medieval settlement. The hill is part of a Site of Special Scientific Interest and National nature reserve. It was in private ownership until the 20th century, when it was donated to the National Trust by Sir Thomas Acland, Colonel Wiggin and Allan Hughes; a stone cairn was erected at the summit to commemorate the event. ==Location== Dunkery is composed of Middle Devonian sedimentary rock, () known as the Hangman Sandstone Formation.〔British Geological Survey 1975 ''Dulverton'' England and Wales sheet 294 Solid & Drift Geology. 1:50,000 scale geological map (Keyworth, Nottingham: British Geological Survey)〕 This supports acidic soils. The ridge along the top of the hill is long. At ordnance datum (OD), the mean height above sea level,〔(【引用サイトリンク】url=http://www.dartmoor-npa.gov.uk/__data/assets/pdf_file/0010/42598/laf-sw_uplands_audit_2008.pdf )〕 Dunkery Beacon is the highest natural point in Somerset,〔(【引用サイトリンク】title=Exmoor National Park Facts and Figures )〕 although the tip of the Mendip TV Mast is higher at OD. Dunkery is ranked 23rd in the UK in terms of dominance and is a Marilyn, meaning that it is a peak with or more of relative height. The nearest higher hill is Yes Tor, away. John Fry, a character in R. D. Blackmore's 1869 novel ''Lorna Doone'', calls it the "haighest place of Hexmoor". Dunkery lies just from the Bristol Channel at Porlock. The shortest route of ascent goes from the car park at Dunkery Gate, and is just long. There are extensive views from the summit, from where the Bristol and English Channel coasts, the Brecon Beacons including Pen Y Fan, Bodmin Moor, Dartmoor, the Severn Bridges and Cleeve Hill away in Gloucestershire are visible. 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「Dunkery Hill」の詳細全文を読む スポンサード リンク
