Watson’s Dodd is a fell in the English Lake District, a minor rise on the main ridge of the Helvellyn range in the Eastern Fells, but a prominent shoulder on the west side of that range.

Fell high and barren landscape feature

A fell is a high and barren landscape feature, such as a mountain range or moor-covered hills. The term is most often employed in Fennoscandia, the Isle of Man, parts of Northern England, and Scotland.

England Country in north-west Europe, part of the United Kingdom

England is a country that is part of the United Kingdom. It shares land borders with Wales to the west and Scotland to the north-northwest. The Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight.

Lake District mountainous region in North West England

The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests and mountains, and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The National Park was established in 1951 and covers an area of 2,362 square kilometres. It was designated a UNESCO World Heritage Site in 2017.


At its foot is the imposing crag of Castle Rock, on which rock climbers have developed some 60 named routes.


Seen from the west, Watson’s Dodd is a noticeable shoulder on the Helvellyn ridge, north of Sticks Pass. The summit stands on the main ridge of the Helvellyn range at the point where the south-west ridge of Great Dodd and the north-west ridge of Stybarrow Dodd meet and merge. From this point a shoulder drops into the valley of the How Beck at Legburthwaite. This shoulder, part of the High Fells of St John’s Common, is sharply defined by the deep valleys of Mill Gill to its north and Stanah Gill to its south. It slopes gently to around the 500 m contour, and then drops more steeply into the valley over a number of rocky crags. Just before reaching the valley, part of this shoulder rises again to the high, precipitous crag known as Castle Rock. [1]

Great Dodd mountain in United Kingdom

Great Dodd is a mountain or fell in the English Lake District. It stands on the main ridge of the Helvellyn range, a line of mountains which runs in a north-south direction between the lakes of Thirlmere and Ullswater in the east of the Lake District. Great Dodd, with a height of 857 m is the highest of the fells in this range to the north of Sticks Pass.

Stybarrow Dodd mountain in United Kingdom

Stybarrow Dodd is a mountain or fell in the English Lake District. It stands immediately north of Sticks Pass on the main ridge of the Helvellyn range in the Eastern Fells, which is situated between the lakes of Thirlmere and the Ullswater.

On the eastern side of the ridge the deep valley of Browndale Beck separates Great Dodd from Stybarrow Dodd, so that Watson’s Dodd has no eastern flanks at all [2] other than its triangular summit plateau.

The highest point on Watson’s Dodd has an elevation of 789 m, a prominence of only 11 m above the slight depression separating it from Stybarrow Dodd. [3]

Watson’s Dodd stands on the main watershed between the Derwent river system to the west, and Ullswater (and the Eden river system) to the east. Streams on the west are now captured by a water leat and diverted into Thirlmere reservoir. [1]

Drainage divide Elevated terrain that separates neighbouring drainage basins

A drainage divide, water divide, divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighbouring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be harder to discern.

Ullswater lake in the English Lake District

Ullswater is the second largest lake in the English Lake District, being approximately nine miles long and 0.75 miles wide with a maximum depth of slightly more than 60 metres (197 ft). Many regard Ullswater as the most beautiful of the English lakes; it has been compared to Lake Lucerne in Switzerland and it is a popular tourist destination. It is a typical Lake District narrow "ribbon lake" formed after the last ice age when a glacier scooped out the valley floor and when the glacier retreated, the deepened section filled with meltwater which became a lake. A total of three separate glaciers formed the lake. The surrounding mountains give Ullswater the shape of a stretched 'Z' with three distinct segments that wind their way through the surrounding hills.

Thirlmere reservoir in the United Kingdom

Thirlmere is a reservoir in the Borough of Allerdale in Cumbria and the English Lake District. The Helvellyn ridge lies to the east of Thirlmere. To the west of Thirlmere are a number of fells; for instance, Armboth Fell and Raven Crag both of which give views of the lake and of Helvellyn beyond. It runs roughly south to north and is bordered on the eastern side for much of its length by the A591 road and on the western side by a minor road. It occupies the site of a former natural lake: this had a fordable waist so narrow that it was sometimes regarded as two lakes. In the 19th century Manchester Corporation constructed a dam at the northern end, raising the water level, flooding the valley bottom, and creating a reservoir to provide the growing industrial city of Manchester with water supplies via the 96 mile-long Thirlmere Aqueduct. The reservoir and the aqueduct still provide water to the Manchester area, but under the Water Act 1973 ownership passed to the North West Water Authority; as a result of subsequent privatisation and amalgamation they are now owned and managed by United Utilities, a private water and waste water company.

Castle Rock

Standing at the top of the Vale of St John’s, the nearly vertical Castle Rock juts out from the hillside with rock faces on three sides. The castle-like profile is made still more picturesque by a garland of mixed woodland around the lower slopes. This rock has attracted the admiring views of visitors since the start of tourism to the Lakes. Thomas West in 1778 referred to the valley ‘nobly terminated by the castle-like rock of St. John’. [4] Jonathan Otley in 1823 knew the rock as ‘the massive rock of Green Crag, sometimes called the Castle Rock of St. John's’. [5] The Scottish lawyer and novelist Sir Walter Scott, wrote his romantic narrative-poem The Bridal of Triermain in 1812. In this, Castle Rock appears as the setting for the Enchanted Castle from which the hero, Sir Roland de Vaux of Triermain, must rescue the maiden, Gyneth. Triermain was the name of a fiefdom in the barony of Gilsland in north-east Cumberland; a pele-tower near Birdoswald still bears the name. [6]

Thomas West was a Jesuit priest, antiquary and author, significant in being one of the first to write about the attractions of the Lake District. Partly through his book, A Guide to the Lakes, the Romantic vision of the scenery and wilderness of the north of England took hold, ushering in a period of continued tourism in the Lakes.

Walter Scott 18th/19th-century Scottish historical novelist, poet and playwright

Sir Walter Scott, 1st Baronet was a Scottish historical novelist, poet, playwright and historian. Many of his works remain classics of both English-language literature and of Scottish literature. Famous titles include Ivanhoe, Rob Roy, Old Mortality, The Lady of the Lake, Waverley, The Heart of Midlothian and The Bride of Lammermoor.

<i>The Bridal of Triermain</i> poem by Walter Scott

The Bridal of Triermain is a rhymed, romantic, narrative-poem by Sir Walter Scott, written in 1813.

The association with Walter Scott’s poem has sometimes led Castle Rock to be called Castle Rock of Triermain, especially by rock climbers in order to distinguish it from another Castle Rock in Gloucestershire.

Climbers have discovered and named over 60 routes up the rock. The precipitous North Crag (75 metres / 246 feet high) was first climbed by Jim Birkett on April Fools' Day, 1939, by a route called Overhanging Bastion. [7] Since 2011 the North Crag has been considered dangerous because a large crack has opened up at the top creating the potential for a massive rockfall. [8] South Crag (35 metres / 115 feet high) is less steep, sunnier and quicker-drying, and holds the less difficult routes. [9]

The summit of Castle Rock has an elevation of 339 m (1,112 ft), with a prominence of 29 m (95 ft) from the fellside behind it. [3]

The summit of Watson’s Dodd is a grassy triangular plateau which slopes gently to the east and is bounded by paths on all three sides. Its highest point, at the western apex of the triangle, is marked by a small cairn. [2]

The view from the summit is ‘sumptuous’. [6] Standing to the west of the main ridge, the summit gives a panoramic view from Blencathra and Skiddaw in the north, round to the Coniston group in the south. The view extends over Thirlmere to the central fells, and is bounded by the western and northwestern fells. On a clear day the hills of south-west Scotland are also visible. [6]


Routes to the top begin from the B5322 road, where parking is available at Legburthwaite or at Stanah village hall. There are no marked paths up the fellside. Keeping to the crest of the ridge (after avoiding the initial rocky crags, or after visiting Castle Rock if wished) leads unfailingly to the summit cairn. [6]

The summit may also be visited by following the well-used paths along the main Helvellyn ridge, though many ridge walkers appear to bypass the summit.


The rocks of Watson’s Dodd are all part of the Borrowdale Volcanic Group, formed on the margin of an ancient continent during a period of intense volcanic activity, roughly 450 million years ago in the Ordovician Period. [10] [11]

Within that group, the bulk of the rocks forming the fell belong to the Birker Fell Andesite Formation. These rocks are among the earliest of the volcanic rocks of the Borrowdale Volcanic Group, and are part of a thick succession of andesite sheets which now outcrop in a wide band around the western and northern sides of the Lake District. [12] These sheets were formed by successive eruptions of mobile andesitic lava from shallow-sided volcanoes. [11]

Between the individual lava flows may be beds of volcaniclastic sandstone, sedimentary deposits formed from the erosion of the volcanic rocks. The geological map shows small deposits of this on the fellside, as well as some lapilli-tuff resulting from a more explosive eruption. [12]

After the eruptions of the Birker Fell Formation the composition of the erupting magma changed from andesitic to dacitic, and as a result the nature of the volcanism became more explosive. [11] In the area to the north of Sticks Pass the Birker Fell andesites are overlain by the Lincomb Tarns Tuff Formation. This formation is one of the most widespread of the volcanic rocks of the Lake District; it seems that the whole district was buried beneath at least 150 m of densely welded ignimbrite, a rock formed from pyroclastic flows of very hot gas and rock. This formation must represent a series of eruptions of truly exceptional magnitude, accompanying the formation of a volcanic caldera, probably in the area around where Helvellyn stands today. [10] :55

On Watson’s Dodd this formation is represented by two members. The Tarn Crags Member makes up Castle Rock, as well as a thin layer higher up the fellside at about the 650 m contour. [12] [13] It is a coarse-grained dacitic lapilli-tuff. Above this thin layer are rocks of the Thirlmere Tuff Member, which covers the top of the fell. First is an area of volcaniclastic breccia, which forms a series of small rocky outcrops on the fellside, and above this is a thick sheet of welded rhyo-dacitic lapilli-tuff in which the individual pieces of semi-molten lava (the lapilli) were flattened under the weight of deposits above them. This rock weathers to a white or pink colour, but it is covered by the smooth grassy turf characteristic of Great Dodd, Watson’s Dodd and Stybarrow Dodd, all of which are covered by the same sheet. [12] [13]


Watson’s Dodd. Dod or dodd is a dialect word of unknown origin, but is common in hill names in the Lake District and the Scottish Borders for bare rounded summits, either free standing or subsidiary shoulders to higher neighbours. [14] :396 [15] The Watson whose name this fell commemorates is unknown. There may (or may not) be a connection with Watson’s Park in the same parish of St John’s. If so, since that name is first recorded in 1734, Watson must have lived no later than the early eighteenth century. [14]
