One of the best known features of Great Langdale are the Langdale Pikes, a group of peaks on the northern side of the dale. From below, they appear as a sharp rocky ridge, though they are only precipitous on their southern side; to the north, the land sweeps gently to High Raise, the parent peak of the range. The Pikes themselves include (from west to east) Pike of Stickle, Loft Crag, Harrison Stickle and Pavey Ark.
Stickle Tarn is a small lake near Harrison Stickle in Lake District, England.The tarn was enlarged by the building of a stone dam in 1838 and is used to supply water for the inhabitants of Langdale.
Harrison Stickle is the high point of the Langdale Pikes and its crags fall south and east from the summit, presenting an arresting view from the valley floor 2,000 ft below, or from further afield. To the north, the main ridge of the central fells passes over Thunacar Knott before climbing to High Raise. The craggy eastern face of this ridge continues north as far as Harrison’s near neighbour, Pavey Ark, visually the most impressive face in the area. The south western border of Harrison Stickle is formed by the deep ravine of Dungeon Ghyll, which cuts through the parapet of the Langdale Pikes and into the lower hinterland of Harrison Combe. Across the Ghyll westwards are Thorn Crag, Loft Crag and finally Pike of Stickle. Below the steep eastern face of Harrison Stickle lie Stickle Tarn and its Ghyll, thus ensuring that all drainage from the fell is to Great Langdale. The tarn is a water filled corrie about 50 ft deep, this being enhanced by a dam. The water is used for public consumption in Great Langdale.
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 barage 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.
