Seatallan is a mountain in the western part of the English
Topography
The Western Fells occupy a triangular sector of the Lake District, bordered by the River Cocker to the north east and Wasdale to the south east. Westwards the hills diminish toward the coastal plain of Cumberland. At the central hub of the high country are Great Gable and its satellites, while two principal ridges fan out on either flank of Ennerdale, the western fells in effect being a great horseshoe around this long wild valley.[1] Seatallan is an outlier of the southern arm.
The main watershed runs broadly westwards from Great Gable, dividing the headwaters of Ennerdale and Wasdale. Travelling in this direction the principal hills are Kirk Fell, Pillar, Scoat Fell, Haycock and Caw Fell. Haycock sends out a long southern ridge terminating in Seatallan.
Seatallan begins at the Pots of Ashness, a broad grassy depression to the south of Haycock. From here a stiff ascent up what may have been a landslip[1] leads directly to the summit. The top of the fell resembles a truncated cone, cut off at an angle and sloping away to the south. This cone in turn stands upon a much broader upland plateau which stretches away five miles (8 km) to the south west. The River Bleng forms the entire western boundary, beginning on the slopes of Haycock and then flowing out in a huge loop to the south west. It finally joins the Irt and continues on to the sea at Ravenglass. The extremity of the Bleng's circuit, near to Gosforth, is given over to lowland cultivation and although belonging topographically to Seatallan could hardly be termed fellside. Higher up the south western shoulder are conifer plantations, both along the Bleng and above the Irt. Open fellside begins two miles south west of the summit.
To the east of Pots of Ashness is the valley of Nether Beck, flowing to
Seatallan's most prominent feature is Buckbarrow, the 400-foot (120-metre) rampart of crags on the southern edge overlooking lower Greendale and Wast Water. Buckbarrow is given a separate chapter in Alfred Wainwright's The Western Fells, and is thus classed as a Wainwright, despite having virtually no topographic prominence of its own. That convention is followed here. Above Buckbarrow are the minor tops of Glade How and Cat Bield, leading onto the great south west shoulder. Seatallan has other areas of much less impressive crag above the upper Bleng (Raven Crag) and Nether Beck (Winscale How).
Geology
Much of the fell is covered in deep drift deposits, but the underlying rock is generally the plagioclase-phyric dacite lava referred to as Seatallan Dacite. Above the Bleng are large areas of diorite, while around Buckbarrow there are outcrops of the andesite Birker Fell Formation. Minor intrusions of rhyolite and basalt have been located to the north.[3]

Ascents
Indirect ascents via Buckbarrow begin from Harrow Head. An alternative bypasses the subsidiary summit to gain Cat Bields from the south west. From Greendale the gill can be followed almost to the tarn, before branching off up the grassy slopes of Seatallan. If preferred Middle Fell can be used as a stepping stone onto Seatallan from the same point. Finally from Nether Beck Bridge the route to Haycock can be used, turning west via Lad Crag Beck to the summit.[1][4]
