Pavey Ark is a fell in the English county of Cumbria. It is one of the Langdale Pikes, lying to the north of Great Langdale, in the heart of the Lake District, immediately to the north-east of Harrison Stickle. Topography From the shores of Stickle Tarn, Pavey Ark gives the impression of being a rocky ridge. In fact this is misleading, and the north-western side is simply an undulating area of moorland, rising towards Thunacar Knott. The summit plateau is characterised by tarns, rocky outcrops and bilberry terraces. Pavey Ark is the largest cliff in the Langdales, but faces east over Stickle Tarn and is less prominent from the floor of Great Langdale away to the south. The main face is a little over across and drops about . To the southwest 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 . Geology The face is an outcrop of the formation named for the fell, the Pavey Ark Member. This consists of pebbly sandstone and breccia and is set within the Seathwaite Fell Formation of volcaniclastic sandstone with interbeds of tuff, lapilli-tuff, breccia and conglomerate. Ascents Pavey Ark is most often climbed from the New Dungeon Ghyll Hotel, located some south. The route follows Mill Gill up to Stickle Tarn, which can also be reached via a much less popular and more strenuous path following the Dungeon Ghyll ravines. From Stickle Tarn there is a choice of routes; one of the most popular is to follow a diagonal slit on Pavey Ark's craggy south-eastern face. This route is known as Jack's Rake, and requires scrambling. Alternative, easier, ascents are available on either side of the main crag. Jack's Rake is the most famous ascent of the Pavey Ark precipice. It is classified as a Grade 1 scramble, but it is within the capability of many walkers, though it does require a head for heights and is considerably harder in bad weather. The rake starts beneath the East Buttress at the precipice's eastern end,
