full_context: Document 1: Flat Fell: Flat Fell is a hill located on the edge of the English Lake District, standing at 272m. It is included in Alfred Wainwright's "Outlying Fells of Lakeland" book, sharing a chapter with Dent. Wainwright's clockwise route to the two summits starts at Wath Brow.
Document 2: Barrow (Lake District): Barrow is small fell in the English Lake District in the county of Cumbria which reaches a height of 455 metres (1,494 feet). It is situated in the quiet and picturesque Newlands Valley just 4 kilometres (2.5 miles) south-west of the town of Keswick. Although modest in height, Barrow commands a fine all-round view, with the vales of Keswick and Newlands being well seen. The name of the fell originates from the Anglo Saxon language meaning a hill or long ridge.
Document 3: Newton Fell: Newton Fell is a hill in the English Lake District near High Newton, south east of Newby Bridge, Cumbria. It lies to the north east of the A590 road. It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland". Wainwright describes two walks, to the summits he calls Newton Fell (north) at 780 ft and Newton Fell (south) or Dixon Heights at 585 ft . There are no public rights of way to either summit, and he states that the walks should be done "by courtesy of the owners and tenants".
Document 4: Walla Crag: Walla Crag is a fell in the English Lake District, near Keswick. The fell is a popular short walk from Keswick and gives superb views over Derwentwater. The western face is prominent in views across the lake and fine views over Keswick are available from the summit.
Document 5: Bowfell: Bowfell (named "Bow Fell" on Ordnance Survey maps) is a pyramid-shaped mountain lying at the heart of the English Lake District, in the Southern Fells area. It is the sixth-highest mountain in the Lake District and one of the most popular of the Lake District fells for walkers. It is listed in Alfred Wainwright's 'best half dozen' Lake District fells.
Document 6: Slate Fell: Slate Fell is a low hill in the North Western part of the English Lake District. It lies only about a mile from the busy market town of Cockermouth, and as such is a popular walk for local dog walkers, the amount of climb being only about 80 metres (250 feet). A public right of way passes over the summit. It is an outlier of the Marilyn Watch Hill, and gives good views of the Lord's Seat group of hills, although it is too low to afford views towards the central Lake District. It lies just inside the boundary of the Lake District National Park.
Document 7: Dove Crag: Dove Crag is a fell in the English Lake District. Situated in the Eastern Fells of the national park, seven kilometres south-south-west of Glenridding, it reaches a height of 792 metres (2,598 feet). The fell is often climbed as part of the Fairfield horseshoe walk but a direct ascent from Patterdale is required to show the fell's full potential, displaying the impressive crags just to the north east of the summit. The highest point was originally unnamed on maps, being just a minor top, but over the years the summit has adopted the name of Dove Crag by mutual accord..
Document 8: Green Quarter Fell: Green Quarter Fell is an upland area in the east of the English Lake District, near Kentmere village, Cumbria. It is the subject of a chapter of Wainwright's book "The Outlying Fells of Lakeland". Wainwright's walk is an anticlockwise circuit from Kentmere, reaching the summit of Hollow Moor at 1394 ft and a nameless summit at 1370 ft and making a detour to admire the tarn of Skeggles Water. He says that the walk offers: ""... a perfectly-balanced and lovely view of upper Kentmere ... that cries aloud for a camera.""

It reaches 1566 ft and Wainwright's route, an anticlockwise circuit from the Birker Fell road, also visits The Pike at 1214 ft . Wainwright admits that the fell "has many shortcomings" and that the view of Scafell Pike and its neighbours is "the only reward for the ascent".
Document 11: Iron Crag: Iron Crag is a mountain in the English Lake District, standing between Crag Fell and Caw Fell. The name of the fell is the source of some confusion, as the summit is unnamed on Ordnance Survey maps.

The Western aspect of the lower slopes, facing Ennerdale Water are known as The Side.

He describes the walk as: ""a connoisseur's piece, every step an uninhibited joy, every corner a delight.""

It is situated on the western shore of Derwent Water within 3 mi of the busy tourist town of Keswick. Its distinctive shape catches the attention of many visitors to the Lakes who feel compelled to climb to the summit after seeing it from the viewpoint of Friars Crag on the opposite side of Derwent Water. Renowned Lake District writer and walker Alfred Wainwright acknowledges the popularity of Cat Bells among fellwalkers of all ability by saying:
