Grey Knotts is a
fell A fell (from Old Norse ''fell'', ''fjall'', "mountain"Falk and Torp (2006:161).) is a high and barren landscape feature, such as a mountain or moor-covered hill. The term is most often employed in Fennoscandia, Iceland, the Isle of Man, pa ...
in the English Lake District. It is situated one kilometre south of the B5289 road as it crosses the Honister Pass. It is well seen from mid- Borrowdale as it rises above Seatoller. Grey Knotts reaches a height of 697 metres (2287 feet) and is part of a ridge which ascends from the woodland behind Seatoller and continues south-west and then south for four kilometres to Great Gable. The fell's name really only applies to the summit rocks, but has been adopted for the entire fell with the high ground in this area, locally known as Seatoller Fell on

Topography

Grey Knotts is a "Wainwright" fell and also qualifies as a Nuttall, but this must be considered a borderline case, as it barely has the required 15 metres of

(then called Plumbago) mines. The mine was started in the 16th century by German immigrants; the graphite found was in a very pure form and in those early days was used only for marking sheep. Later, however, graphite was found to be suitable for lining the casting moulds for cannon and musket balls, which caused its value to soar in the 17th century, as England, France and the Dutch Republic built up their armies. The graphite was also used in

Ascents

Grey Knotts can be ascended from Seathwaite or Seatoller in Borrowdale or from the top of the Honister Pass. The route from Seathwaite goes up Newhouse Gill thus allowing the walker to inspect the old graphite mines while the path from Seatoller has to use the B5289 road for a kilometre before going onto the fell and following a wall for some distance then climbing the northern end of Raven Crag to reach the summit. Grey Knotts is often climbed from the top of the Honister Pass which gives the advantage of starting at a height of 356 metres (1167 feet). Walkers often use Grey Knotts as a stepping stone for the ascent of Great Gable from Honister Pass also passing over the adjoining fells of Brandreth and Green Gable on the way.


Summit

The top of the fell is dotted with grey tors of rock and two of these give the fell twin tops of equal height, the eastern top has an Ordnance Survey
