Mosedale Viaduct

Mosedale Beck is a river in Cumbria, England, which rises on the northern slopes of Great Dodd and flows north east, to the south of Clough Head before joining the River Glenderamackin to the east of Threlkeld village. This then flows west, alongside the A66 road south of Blencathra, to form the River Greta which flows into the River Derwent. Shortly before joining the Glendaramackin, Mosedale Beck is crossed by the Mosedale Viaduct of the former Cockermouth, Keswick and Penrith Railway, now a footpath.

Bannerdale Crags is a fell in the English Lake District. It stands between Blencathra and Bowscale Fell in the Northern Fells.

Clough Head ( ) (meaning: hill-top above the ravine) is a fell, or hill, in the English Lake District. It marks the northern end of the main ridge of the Helvellyn range and is often walked as part of the ridge walk. The fell stands south of the village of Threlkeld and the A66 road, and it forms the steep eastern side of the tranquil valley of St John's in the Vale. On its western side the fell displays a dark mass of rocky crags and a deep-set rocky ravine. On the other side it has smooth grassy slopes. Beneath the north face is the steep valley or clough from which Clough Head gets its name. Also beneath the steep northern face lies the lower hill of Threlkeld Knotts, a granite hill which has been much quarried round its margin. A number of different types of rock are found on and around Clough Head, which were formed in very different circumstances. These include deep-sea sedimentation, effusive volcanic lava flows, explosive volcanism, an intrusion of granite, mineralisation and finally glacial sculpting. To understand the geology of Clough Head is to understand much of the geology of the Lake District. An old route known as the Old Coach Road passes beneath Clough Head. Most of the fell is Open Access land, which walkers can enter from either end of the Old Coach Road, or from a lane south of the village of Threlkeld. Four main routes lead to the summit.

The Threlkeld Quarry and Mining Museum is a museum located in Threlkeld three miles (4.8 km) east of Keswick, in the Lake District in Cumbria. It includes a quarry with a collection of antique machinery, such as locomotives and cranes, an underground tour of a simulated mine, a geological and mining museum, and mineral panning.

Threlkeld is a village and civil parish in the north of the Lake District in Cumbria, England, to the east of Keswick. It lies at the southern foot of Blencathra, one of the more prominent fells in the northern Lake District, and to the north of the River Glenderamackin. The parish had a population of 454 in the 2001 census, decreasing to 423 at the Census 2011.

Great Dodd (meaning: big round hill) is a mountain or fell in the English Lake District. It stands on the main ridge of the Helvellyn range, a line of mountains which runs in a north–south direction between the lakes of Thirlmere and Ullswater in the east of the Lake District. Great Dodd, with a height of 857 metres (2,812 ft) is the highest of the fells in this range to the north of Sticks Pass. Walkers may approach Great Dodd from either High Row near Dockray to the east, or from Legburthwaite to the west – or along the main ridge track from either north or south. Scramblers with climbing skills may be attracted to three gill climbs on the western side of the mountain. The summit of Great Dodd is a smooth, grassy, rounded dome, like its two southern neighbours, Watson's Dodd and Stybarrow Dodd. Together, these three are sometimes called ‘The Three Dodds’. These three are made of volcanic rocks of the Borrowdale Volcanic Group, and the tops of all three are covered by the same sheet of rock, which was formed in a series of huge volcanic explosions accompanying the formation of a volcanic caldera about 450 million years ago. Two attempts were made to mine mineral veins in the rocks of Great Dodd, but neither attempt was successful.

Blencathra, also known as Saddleback, is one of the most northerly of the Cumbrian Mountains, in the English Lake District. It has six separate fell tops, of which the highest is the Hallsfell Top at 2,848 feet (868 metres).

Bowscale Fell is a hill in the English Lake District. It rises above the village of Mungrisdale in the Northern Fells. Bowscale Fell stands at the extreme north east the Blencathra group, connected to this higher fell by the intervening Bannerdale Crags. In common with many fells the western slopes are smooth and convex while the eastern side exhibits crags.

Threlkeld railway station was situated on the Cockermouth, Keswick and Penrith Railway between Penrith and Cockermouth in Cumbria, England. The station served the village of Threlkeld. The station opened to passenger traffic on 2 January 1865, and closed on 6 March 1972.

Watson's Dodd is a fell in the English Lake District, a minor rise on the main ridge of the Helvellyn range in the Eastern Fells, but a prominent shoulder on the west side of that range. At its foot is the imposing crag of Castle Rock, on which rock climbers have developed some 60 named routes.

The River Glenderamackin, the Glendermackin or Glendermackin Beck is a watercourse in Cumbria, England. It is a headstream of the Greta. The river rises on Mungrisdale Common north of Blencathra and drains much of the eastern and southern sides of the mountain. The river runs east, then north before sharply turning south at the village of Mungrisdale, skirting almost all around the bottom of Souther Fell. Latterly, the river turns west to the north of Hutton Moor End and the Trout Beck joins it at Wolt Bridge to the south of Lowside. Not too far away it is soon swelled again by the waters of Mosedale Beck next to Dobson's Bridge. The Glenderamackin continues past Threlkeld, at which point it conjoins with St. John's Beck to form the River Greta.

St. John's Beck is a river in the Lake District of Cumbria, England. The beck has its beginning as an outflow of Thirlmere, whence it flows northwards through St. John's in the Vale, towards Threlkeld, where it meets the River Glenderamackin to form the River Greta.
