filled corrie about 50 ft deep, this being enhanced by a dam. The water is used for public consumption in Great Langdale. Pavey Ark Pavey Ark is 700 m (2,297 ft) high. The main face is a little over a quarter of a mile across and drops about 400 ft. To the south-west it merges into the crags of Harrison Stickle, while the northern end peters out into the valley of Bright Beck. Stickle Tarn is wholly within the territory of the Ark, a corrie tarn which has been dammed to create additional capacity. The stone-faced barrage is low enough not to spoil the character of the pool, and the water is used for public consumption in the hotels and homes below. The tarn has a depth of around 50 ft. Other fells Great Langdale's highest fell is Bow Fell. Other notable Langdale fells are Crinkle Crags, at the head of the Oxendale valley, and Pike o' Blisco on the southern side of the valley. Dungeon Ghyll Dungeon Ghyll is a ravine on the north side of the valley, starting on the fell slopes between Harrison Stickle and Loft Crag/Pike o' Stickle. It is narrow, and a No Through Route for walkers. Much more open is Stickle Ghyll, which descends from Stickle Tarn. There is a well–trodden path from the Stickle Ghyll car park opposite the New Dungeon Ghyll hotel up to the tarn, parts of which have been improved with stone slabs to reduce erosion. Another waterfall, known as Dungeon Ghyll Force, is up a path behind the Old Dungeon Ghyll hotel. Middle Fell Bridge here is the bridge centring in the plot of the landmark film 1945 Brief Encounter. Cultural reference Letitia Elizabeth Landon's poetical illustration, Langdale Pikes (1832), to a picture by Thomas Allom, ignores the mountains and eulogises on the excellent trout fishing in the river. Tourism There are a number of popular fell walking routes include Bowfell, Crinkle Crags, the Langdale Pikes and England's highest mountain, Scafell Pike. There are also rock-climbing spots on the valley floor, such as Raven Crag, Gimmer Crag and White Ghyll, providing some of the most spectacular rock routes in the UK. The Langdale Leisure Limited company, consisting of a hotel, timeshare lodges and leisure facilities, operates in the valley. Old Dungeon Ghyll The Old Dungeon Ghyll Hotel was originally a farm and inn. It was bought by the historian
