Mardale Ill Bell
Mardale Ill Bell is a fell in the English Lake District, rising to the south west of Haweswater Reservoir. It stands on the watershed between Mardale and Kentmere and is the highpoint of the south-eastern ridge of High Street, midway on its course to Harter Fell. Topography. The head of the Kentmere valley lies to the south-west of the fell with rough slopes leading down over scree to Kentmere Reservoir. Mardale Ill Bell sends out a short grass-topped spur, Lingmell End, which splits the head of the valley into two. The north-eastern face  of Mardale Ill Bell forms the craggy backdrop to Blea Water. This perfect corrie tarn is the deepest in the Lake District at 207 ft. Its outflow feeds Haweswater, joining with that of a second tarn, Small Water. Between the two, Mardale Ill Bell throws out the rocky spur of Piot Crag. Two tiers of crag drop down to the confluence at Mardale Waters. South-east of the summit a rough narrowing ridge drops to Nan Bield Pass at 2,100 ft, before rising again over rocky steps to Harter Fell. Nan Bield was the ancient trading route between Kentmere and  the now drowned village of Mardale Green, submerged by the raising of Haweswater in the 1940s. Near the shore of Small Water on the descending path are a number of stone shelters, pointers to the earlier importance of the pass. These each provide refuge for one person "in extremis", entrance being via crawling. North-west from Mardale Ill Bell the grassy ridge crosses a wet depression and then expands into a wide plateau, triangular in plan. High Street and Thornthwaite Crag are at the other two corners, with the Roman road crossing north to south. Summit. The summit has two  large cairns on grass, the northern one being the top. The view westwards is confined by higher fells but the Ill Bell ridge and Coniston range are seen to good effect. Blea Water and Small Water can be brought into sight from the rim of the crags. Ascents. The most popular routes of ascent are on the Mardale side. From the road end Nan Bield pass can be used, or the impressive scenery of Piot Crag can be attained from the shore of either Blea or Small Water. From Kentmere, Nan Bield provides the obvious route, although a pathless climb  up to the top of Lingmell End is possible.
