Mungrisdale Common

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).

Lake District High Fells is a Special Area of Conservation (SAC) in Cumbria, England, which was designated in 2005. It is a multi-site SAC with an area of 27,003.07 ha (104.2594 sq mi) consisting of 10 separate sites including the summit of Scafell Pike, which at 977 m (3,205 ft) is the highest mountain in England. The SAC takes its name from the English Lake District and "Fell", the local word for a mountain. It protects 16 habitat types listed in the European Union's Habitats Directive. As is usual with SACs in England, the protected areas are also covered by Site of Special Scientific Interest (SSSI) designations. The ten component sites are as follows: Armboth Fells SSSI Birk Fell SSSI Buttermere Fells SSSI Helvellyn & Fairfield SSSI Honister Crag SSSI Pillar & Ennerdale Fells SSSI Scafell Pikes SSSI Shap Fells SSSI Skiddaw Group SSSI Wasdale Screes SSSI (Wast Water is a separate SAC protecting the lake) Additionally: River Derwent & Tributaries SSSI (overlaps the SAC) River Eden & Tributaries SSSI (overlaps the SAC)

Skiddaw Group SSSI is a site of special scientific interest in the Lake District High Fells, England. Its shape is approximately an irregular circle centred near Great Calva, with an area of 10,256.3 hectares (39.600 sq mi). The high ground creates a watershed between the Caldew Operational Catchment with water flowing north towards Carlisle, and the Ellen and West Coast and Derwent Operational Catchments flowing towards the west coast at Workington and Maryport. The area includes the Skiddaw Forest nature reserve. The SSSI is designated for its flora and fauna, and for its geology. The geology includes the Skiddaw Group of sedimentary rock formations, and the Caldbeck Fells former mining area. Fells above 2,000 feet (610 m) include High Pike, Carrock Fell, Knott, Great Calva, and Bowscale Fell. The highest peaks are in the Skiddaw area, including Skiddaw itself, Long Side, Carl Side, Little Man, Lonscale Fell and, further east, Blencathra. The SSSI is divided into a patchwork of "units" which are used as the level of geographic detail for reporting overall features and conditions. Each unit is identified by the Ordnance Survey grid reference at the centre of the unit, its area in hectares, the date it was last surveyed, and the drainage catchment it is located in. For example Bassenthwaite Common, which is unit 27, is nearly 700 ha (2.7 sq mi) centred at NY252299 in the Dash beck catchment. The habitat is there is dwarf shrub heath which, when surveyed in November 2010, was in an "unfavourable – recovering" condition.

Great Calva is a fell in the Lake District, England. It is in the Northern Fells, lying roughly at the centre of this region of high ground. As a result, it is distant from roads and quite remote by Lakeland standards. Great Calva stands at the head of a major geological fault running through the centre of the Lake District, and so from the summit it is possible to see all the way south over Thirlmere. The subsidiary summit of Little Calva lies to the west. It is in the centre of the Skiddaw Group SSSI.

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.

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

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.

Knott is a mountain in the northern part of the English Lake District. It is the highest point of the Back o'Skiddaw region, an area of wild and unfrequented moorland to the north of Skiddaw and Blencathra. Other tops in this region include High Pike, Carrock Fell and Great Calva. The fell's slopes are mostly smooth, gentle, and covered in grass, with a few deep ravines. It stands a long way from a road and requires a long walk across the moor top get to it; this, as well as the fact that it is hidden from the rest of the Lake District by the two aforementioned giants, make it one of the most unfrequented tops in the Lakes. When it is climbed it is most often from Mungrisdale or from the north via Great Sca Fell. The word Knott is of Cumbric origin, and means simply "hill".

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.

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.

Naddle Beck is a minor river of Cumbria, England. Rising beneath Dodd Crag, Naddle Beck flows northward to meet the River Greta. The major tributary of Naddle Beck is Shoulthwaite Gill, which drains the eastern side of High Seat and Bleaberry Fell. Mere Gill joins Shoulthwaite Gill beneath an old fort on Castle Crag. Other tributaries of Naddle Beck are Brown Beck and William's Beck.

Lonscale Fell is a hill in the English Lake District. Its pointed second top is instantly recognisable, standing at the eastern end of the Skiddaw massif. The fell is easily climbed from Keswick or from Skiddaw House to the north. Although now primarily a sheep pasture, it once saw considerable mining activity beneath the long eastern wall of crag.
