Grasmoor

Grasmoor is a mountain in the north-western part of the Lake District, northern England. It is the highest peak in a group of hills between the villages of Lorton, Braithwaite and Buttermere, and overlooks Crummock Water.

Grasmoor is distinguished by its steep western flank, dropping dramatically to Crummock Water. This face is however not suitable for rock climbers as there is little clean rock, although Alfred Wainwright describes a challenging route up the face in his '' Pictorial Guides to the Lakeland Fells''.Alfred Wainwright: ''A Pictorial Guide to the Lakeland Fells, Book 6, The North Western Fells'': Westmorland Gazette (1964): To the east the fell is linked to others by Crag Hill and Coledale Hause. Grasmoor is also home to the most extensive scree slopes in the North Western Fells.

Name

Grasmoor takes its name from the Old Norse element ''grise'', meaning wild boar. This element appears in other Lake District place names, including Grisedale Pike and Grizedale Forest.

Topography

The North-Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north–south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter Pass and Newlands Pass, includes Grasmoor.

The highest ground in the North-Western Fells is an east–west ridge in this central sector, beginning with Grasmoor above Crummock Water and then gradually descending eastwards over Crag Hill, Sail, Scar Crags and Causey Pike. Grasmoor has the greatest elevation, although Crag Hill stands at the hub of the range.

From the valley floor near Little Town at the eastern end, the ridge requires of gradual ascent to attain the summit of Grasmoor. Starting at the shores of Crummock Water in the west, the same is achieved by a single slope of scree in less than a quarter of the distance. Grasmoor is Lakeland's terminal height ''par excellence''.

The summit is at the west end of a broad, gently domed promenade of moss and short grass, with a narrowing in the middle where the deep bowl of Dove Crags bites into the northern face. To the east of this plateau are broad smooth slopes descending to a wide unnamed col at . This connects onward to Crag Hill. At the western end the summit area narrows, culminating at the subsidiary top of Grasmoor End () which crowns the western face. Great fans of scree descend to the lakeside road below. Grasmoor has one minor ridge which descends south-westward over Lad Hows () before a steeper fall to the valley floor.

To the south of Grasmoor is the valley of Rannerdale, which flows to Crummock Water between Lad Hows and the neighbouring Wandope. This drainage is supplemented by Cinderdale Beck, separating Lad Hows from the main body of the fell. The northern flank of the ridge stands above Liza Beck, in the valley of Gasgale Gill. This stream also makes due west for Crummock Water, but is diverted northward by the low top of Lanthwaite Hill to join the Cocker after its exit from the lake. An area of lowland to the north-west is thus annexed to Grasmoor from the natural territory of Whiteside.

Geology

The surface rocks of Grasmoor are composed primarily of the Ordovician Kirkstile Formation. These are laminated mudstone and siltstone, typical of the Skiddaw range.British Geological Survey: 1:50,000 series maps, ''England & Wales Sheet 29'': BGS (1999) There is no history of mining beneath the slopes of Grasmoor.Adams, John: ''Mines of the Lake District Fells'': Dalesman (1995) The bowl of Dove Crags is one of the largest glacial combs or cirques in the Lake District, yet has no tarn, but dry hollows noted as curious by Alfred Wainwright. This cavity has originated or been enlarged by a very large landslip (rock slope failure)which over at least the last 20,000 years has been displacing the Liza Beck northwards, narrowing Gasgale Gill valley and provoking the unusually extensive scree slopes of Whiteside.

Summit

The top of the fell lies toward the western end of the summit plateau, marked by a huge sprawling cairn. There are many smaller cairns and the top is characterised by sheep-mown grass. The view is extensive although robbed of some foreground by the extent of the summit. All of the major Lakeland ranges are in sight with the exception of the Far Eastern Fells, with High Stile above Crummock Water perhaps the highpoint. This is best seen from the western end of the plateau.Bill Birkett: ''Complete Lakeland Fells'': Collins Willow (1994):

Ascents

The obvious way is direct up the screes from Lanthwaite on the Crummock Water road, picking through the rock scenery above to appear on Grasmoor End from the north west. This involves of ascent in about . From the same starting point a detour along Liza Beck/ Gasgale Gill can be used to give access to the northern slopes. A way can then be found almost direct to the summit around the rim of Dove Crags. From Rannerdale a choice of routes arises, either climbing the Lad Hows ridge or following Red Gill a little to the west. Finally Coledale Hause can be used to gain the main ridge between Crag Hill and Grasmoor. This can be reached from Lanthwaite or as the first objective of a longer march from Braithwaite in the east. Coledale Hause connects to Hopegill Head and the fells to the north, providing further indirect possibilities.

Protection

Grasmoor is within Buttermere Fells Site of Special Scientific Interest which is also within Lake District National Park. The land surface of Grasmoor mountain is owned by the National Trust.
