The Nidderdale Caves are a series of caves in Upper Nidderdale in North Yorkshire, England. There are two cave systems and most of the caves are in some way linked with one or the other. The smaller system is the Eglin cave system in the valley of How Stean Beck, a tributary of the River Nidd, associated with How Stean Gorge. The larger system is the Goyden cave system under the valley of the River Nidd, which flows east from Scar House Reservoir, then south, and shortly after disappears underground down several sink holes to reappear at the rising just beyond the village of Lofthouse. Cavers are able to access several sections of this system via the different entrances. The caves are a Site of Special Scientific Interest designated in 1987 under the name Upper Nidderdale.〔(Natural England: SSSI citation )〕 == Entrances == From north to south: # (Manchester Hole ) (NGR SE 100736 Length 578m) # (Bax pot ) (alternative entrance to Manchester Hole Divers chamber, providing through trip) # (Lesser Stream pot ) (entrance into connecting passage Eternal Optimist, Linking Manchester Hole and Goyden pot) # (Goyden pot ) (NGR SE 099761 Length 3.7 km) # Back Steps (alternative entrance to Goyden pot main chamber) # (Church pot ) ( alternative entrance to Goyden pot Gaskell’s passage, flood exit route) # (Limley pot ) (alternative entrance to Goyden pot, Mud Hall) # Zanussi pot (close to Limley pot now sealed closed) # (Guscott pot ) (NGR SE 100757 Length 103m) # (Frog pot/Aquamole series ) (NGR SE 101756 Length 640m) # Harrogate pot (close to Frog pot, now sealed closed) # Dry Wath entrance (original entrance to New Goyden pot now blocked) # Vulcan rift pot (close to New Goyden main entrance bypassing first pitch, now blocked) # (New Goyden pot ) (NGR SE 102754 Length 2.2 km) # (Thrope Edge pot ) (alternative entrance to New Goyden pot South Avens) # Howgill pot (alternative entrance to New Goyden pot South Avens, now blocked) # (Nidd Head NW Rising ) (NGR SE 104731 Length 850m) # (Nidd Head SE Rising ) (NGR SE 105730 Length 250m) Entrances in bold are classed as distinct caves in their own right and entrances not in bold are alternative entrances into those caves. 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「Nidderdale Caves」の詳細全文を読む スポンサード リンク
