Details

There are 5 viable routes from Thunacar Knott

The Wainwright guides indicate “ridge routes” from each fell and although this is useful, it doesn't always allow for effective route planning. The routes shown here are the Wainwright ridge routes (indicated with ) plus any other viable routes (indicated with ), not necessarily linked by a ridge. This list provides a more comprehensive network of potential routes that can be used when planning days out on the fells.

All routes have been plotted in the OS Maps app. The distance, ascent and time values are those given for the plotted routes. Time values are for moderately fit walkers without breaks. They should therefore be considered minimum values for the purposes of route planning.

Notes

Thunacar Knott is a central hub of the Langdale Pikes and near neighbours. With a little planning, it's possible to combine this fell with all those listed here, plus Loft Crag, into a single day walk, bagging seven Wainwrights in the process.

Classification

DoBIH No

Local

Birkett, Fellranger, Synge, Wainwright

Birkett

Lake District hills over 1,000ft listed in Bill Birkett's Complete Lakeland Fells. There are 541 Birketts, 211 are also Wainwrights.

Fellranger

Lake District hills included in Mark Richards' Fellranger walking series, a set of eight volumes inspired by the Wainwright guides. There are 230 Fellrangers, 209 are also Wainwrights. This is a curated list, not based on height criteria.

Synge

Lake District hills over 300m listed in Tim Synge's The Lakeland Summits. The book aims to list every significant summit over 300m in height within the National Park, 646 in total. It includes all 214 fells in Wainwright's Pictorial Guides, including Castle Crag at 290m.

Wainwright

Lake District hills included in volumes 1-7 of Wainwright's A Pictorial Guide to the Lakeland Fells. There are 214 Wainwrights in all. This is a curated list, not based on height criteria.

National

Nuttall, Subsimm

Nuttall

Hills in England and Wales that are at least 2,000 feet (610m) high and with a drop of at least 15m on all sides, as published in the two volumes of The Mountains of England and Wales by John and Anne Nuttall. There are 169 Nuttalls in the Lake District, 114 are also Wainwrights.

Subsimm

British hills that are at least 600m high and fall short of a drop of 30m on all sides by up to 10m. There are 12 Wainwrights in this class.

Notes

The highest point at Thunacar Knott is at the southern cairn and that is the top for all classifications except for Wainwright, who preferred the northern top.

Members, formations and groups

Member

A smaller unit of rock that shares common charateristics and features, often used in geology to describe specific layers within a formation.

Formation

A larger unit of rock that is distinct from other formations above and below. A formation may include two or more members.

Group

A stratigraphic unit that includes two or more associated formations that are usually contiguous or contain significant features in common.

Suite

A geological unit containing intrusive, highly deformed, or metamorthic rocks of the same type, lacking discernable stratification.

Complex

A geological unit containing intrusive, highly deformed, or metamorthic rocks of different types, lacking discernable stratification.

Notes

These volcanistic sedimentary rocks were laid down in shallow seas. They are predominantly formed from sandstone (coarse-grained) and siltstone (fine-grained) units. They may be interbedded with tuff, lapilli-tuff, breccia and conglomorate, and may also include andersite sills.

Details

Daylight, dawn, dusk and midday

Daylight

The period of Daylight begins at sunrise and ends at sunset.

Dawn and dusk

The given figures are for Civil Dawn and Civil Dusk. These mark the start and end of Civil Twilight, that period before sunrise and after sunset when there is still enough light in the sky to easily undertake most outdoor activities without artificial light. However, do bear in mind that light levels during twilight will vary depending on cloud cover. Before dawn and after dusk, a headtorch is recommended.

Midday

Midday is the point, half way between sunrise and sunset, when the sun is at its highest point in the sky. Midday is also known as Transit or Solar Noon and may not be the same as noon in Civil Time (12 o'clock).

Notes

Aim to complete your walk before sunset, leaving the evening twilight period as a buffer in case the walk takes longer than expected. Always carry a headtorch.
