Hardknott Pass

Hardknott Roman Fort is an archeological site, the remains of the Roman fort Mediobogdum, located on the western side of the Hardknott Pass in the English county of Cumbria. The fort was built between 120 and 138 on a rocky spur, and was initially garrisoned by a detachment of the Cohors IV Delmatarum from the Dalmatian coast (in modern Croatia). It was abandoned around a decade later, then reoccupied circa 200 and remained in use for much of the next two centuries.

Hard Knott is a fell in the English Lake District, at the head of Eskdale.

Cockley Beck is a small hamlet, situated in the Duddon Valley in Cumbria, England. Historically, the hamlet was part of Lancashire. Located today within the Lake District National Park, it was established in the late 16th century, and is closely associated with the mining of copper ore in Cumbria.

Slight Side is a fell in the English Lake District it stands 25 kilometres (16 miles) east southeast of the town of Whitehaven and reaches a height of 762 metres (2,499 ft). Slight Side lies at the south western edge of the Scafell Massif, a four-kilometre-long (2+1⁄2 mi) crescent of high ground which includes the highest ground in England. The fells names derives from the Old Norse language and means "The mountain shieling with the level pastures", it is a combination of the Norse words "sletta" and "saetr". With a shieling meaning a shepherds hut or a mountain pasture used in the summer.

Wallowbarrow Crag is a hill of 292 metres (958 ft) in the Lake District, England. It is on the west of the Duddon Valley, across the valley from the village of Seathwaite. Wallowbarrow Crag is a Fellranger, being included in Mark Richards' The Old Man of Coniston, Swirl How, Wetherlam and the South as one of the 18 (now 21) of his 227 (230 with the extension of the national park) summits which are not in Alfred Wainwright's list of 214. It is also classified as a Tump. It is a recognised site for rock climbing.

Walna Scar is a hill in the English Lake District, lying just south of a pass of the same name in the Coniston Hills. Its summit at 2,035 feet (620 m) is only slightly higher than the pass. Walna Scar is the highest of Wainwright's The Outlying Fells of Lakeland. He describes an ascent from Coniston, continuing past the main summit to a second summit at White Maiden before returning to the south. Walna Scar can be climbed from Coniston or from the Duddon Valley. Both routes meet at the top pass of the Walna Scar Road, a restricted byway, and then head south to the summit. Walna Scar road was an old packhorse route, termed by Wainwright “the ancient highway over Walna Scar”, and formed an important medieval conduit from Furness Abbey to Coniston for the wooltrade, (as well perhaps as having been used in the Bronze Age). Geologically, Walna Scar contains a rich seam of distinctively striped slate which was quarried until the early 20th century. This was widely used for flooring in the North of England. The quarry can still be seen today on the slopes overlooking the Duddon Valley.

Seathwaite Tarn is a reservoir in the Furness Fells within the English Lake District. It is located to the south of Grey Friar and to the west of Brim Fell (on the ridge between The Old Man of Coniston and Swirl How) and north east of the village of Seathwaite on the east of the Duddon Valley. In order to create a source of drinking water the existing tarn was considerably enlarged with a dam in 1904. During the dam construction some of the navvies rioted damaging buildings in the village, several rioters were shot, one dying the next day. The dam is almost 400 yards (366 m) long and is concrete cored with slate buttresses, the resulting depth of the tarn being around 80 feet (24 m). Water is not abstracted directly from the tarn, but flows some distance downriver to an off-take weir. On the slopes of Brim Fell, above the head of the reservoir, are the remains of Seathwaite Tarn Mine. This was worked for copper in the mid 19th century, and also appears as a location in the novel The Plague Dogs by Richard Adams. Rocks in the area were the first confirmed occurrence of wittichenite in the British Isles.Bronze Age ring cairns were found close to Seathwaite Tarn in 2003, these were excavated in 2003 and 2007.Seathwaite Tarn has suffered from acidification. An experiment in 1992–1993 to reduce the acidification by using a phosphorus-based fertiliser increased the pH from 5.1 to 5.6 and changed the levels of the different species of the rotifer assemblage significantly.
