Topography

Grey Knotts is a “Wainwright” fell and also qualifies as a Nuttall but this must be a borderline case as it barely has the required 15 metres of prominence
Topographic prominence
In topography, prominence, also known as autonomous height, relative height, shoulder drop , or prime factor , categorizes the height of the mountain's or hill's summit by the elevation between it and the lowest contour line encircling it and no higher summit...

All the highlights of Grey Knotts are situated on the eastern (Borrowdale) side of the fell, Raven Crag, known as Gillercombe Buttress to rock climbers
Climbing
Climbing is the activity of using one's hands and feet to ascend a steep object. It is done both for recreation and professionally, as part of activities such as maintenance of a structure, or military operations.Climbing activities include:* Bouldering: Ascending boulders or small...

, it is a popular area for bouldering
Bouldering
Bouldering is a style of rock climbing undertaken without a rope and normally limited to very short climbs over a crash pad so that a fall will not result in serious injury. It is typically practiced on large natural boulders or artificial boulders in gyms and outdoor urban areas...

 using the large amount of large boulders that have become detached from the main crag, there are also several conventional climbing routes up the main crag. Gillercomb (spelt like this on map) is a fine example of a hanging valley from which issues the stream of Sour Milk Gill which descends into Borrowdale in a series of picturesque cascades.

Geology

The principal rock types are the plagioclase

Andesite is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. In a general sense, it is the intermediate type between basalt and dacite. The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. Magnetite,...

Graphite Mine

Also on the Borrowdale side of the fell at the upper end of Newhouse Gill at grid reference is the site of the former Borrowdale graphite
Graphite
The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Ancient Greek γράφω , "to draw/write", for its use in pencils, where it is commonly called lead . Unlike diamond , graphite is an electrical conductor, a semimetal...

 (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 Holland built up their armies. The graphite was also used in pencil

. The mine closed in 1891 after new techniques meant that graphite no longer needed to be so pure, so the Borrowdale mine became uneconomic.

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 and view

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 trig point
