Great Sca Fell

The Skiddaw Group is a group of sedimentary rock formations named after the mountain Skiddaw in the English Lake District. The rocks are almost wholly Ordovician in age (Tremadoc through Arenig to Llanvirn epochs) though the lowermost beds are possibly of Cambrian age. This rock sequence has previously been known as the Skiddaw Slates, the Skiddaw Slates Group and the Skiddavian Series. Its base is not exposed but in its main outcrop area, it is considered to be in excess of 5,000 metres (16,000 ft) thick though less elsewhere. It consists largely of mudstones and siltstones with subordinate wacke-type sandstones. Their main occurrence is within the northern and central fells of the Lake District, either side of the major ENE-WSW aligned Causey Pike Fault, but inliers are found at Black Combe in the south of the Lake District and at Cross Fell in the North Pennines.

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".

Brae Fell is a fell in the English Lake District, situated 12 kilometres (7+1⁄2 miles) north of Keswick it reaches a height of 586 m (1,923 ft) and is regarded as part of the Caldbeck Fells along with High Pike and Carrock Fell even though it has ridge links to the Uldale Fells. It forms part of the Skiddaw Group SSSI, a Site of Special Scientific Interest for its ecology and geology. The fell's name has Scottish overtones and translates from the Scots language as a hillside or slope. Its northern flanks face the Scottish Borders country across the Eden Valley and Solway Firth.

Meal Fell is a small fell in the northern region of the English Lake District, it is situated seven kilometres (4+1⁄4 miles) south-west of the village of Caldbeck and is one of the four main Uldale Fells (the others being Longlands Fell, Great Cockup and Great Sca Fell).

Lowthwaite Fell is a hill in the Northern Fells of the Lake District in England. It is a grassy eminence, rising to a height of 509 metres (1,670 ft), above sea level, on the ridge between Longlands Fell and Great Sca Fell.

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.

Great Cockup is a fell in the northern region of the English Lake District, one of the four Uldale Fells (the others being Longlands Fell, Great Sca Fell and Meal Fell).

Longlands Fell is a small fell in the northern part of the English Lake District. It is situated in the high ground known as the Uldale Fells, 5.5 kilometres south west of the village of Caldbeck. It reaches a height of 483 m (1,585 ft) and it is (along with Binsey) the most northerly fell in the Lake District.

The Dash Valley is a small valley in the English Lake District. It has only one dwelling, Dash Farm, the fields of which spread right across the valley. The valley is flanked on the northern side by Great Cockup, and on the southern side by Bakestall, part of the Skiddaw massif. At the head of the valley Dash Beck, the river which flows through the valley, falls dramatically forming Dash Falls (aka Whitewater Dash), which Wainwright called the finest succession of falls in the Lake District. A private road leads up the valley to Dash Farm, and a track branches off this and goes all the way up the valley, past Dash Falls to Skiddaw House, a former shepherd's hut now used as a youth hostel. The upper part of the valley is in the Skiddaw Group SSSI.

Bakestall is a fell in the English Lake District, it is situated seven kilometres (4+1⁄4 miles) north of Keswick in the quieter, even secluded northern sector of the national park known as ‘Back o’ Skiddaw’.
