The Burn of Ayreland (or Ireland) is a northwesterly flowing coastal stream on Mainland Orkney, Scotland, that discharges to the Clestrain Sound about two miles south of Stenness.〔United Kingdom Ordnance Survey Map Landranger 6, Orkney Mainland, 1:50,000 scale, 2003〕 Draining chiefly agricultural lands elevated mosses and moorland. This stream has a notable lack of turbidity and a pH level of approximately 8.〔C.M Hogan, ''Natural History of the Orkney Islands'', Aberdeen (2006)〕 Armouring of the stream bottom consists of pebbles, cobbles and occasional boulders. ==Prehistory and history== This burn is located a few miles south of very significant Neolithic and Iron Age archaeological sites. A few miles to the north are the Standing Stones of Stenness and the Ring of Brodgar.〔J. Gunn, ''Orkney, the Magnetic North'', Thomas Nelson and Sons, Edinburgh (1932)〕 About three miles to the northeast is the Neolithic Maes Howe site. ==See also== *Midmoss *Waulkmill Bay 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「Burn of Ayreland」の詳細全文を読む スポンサード リンク
