Arnison Crag is a fell in the Lake District, an outlier of the
Fairfield group in the Eastern Fells and looks down on Patterdale
village and the upper reach of Ullswater.
Although properly a
north eastern ridge of Birks and having little topographical prominence,
Arnison Crag was classed as a separate fell by Alfred Wainwright in his
Pictorial Guide to the Lakeland Fells.
Birks, which is itself a
satellite of St Sunday Crag, resides on a southwest to northeast ridge.
Below the summit and about half way down the main slope, a level
spur juts out eastward and then curves around to the north to run
parallel with Birks.
At the far end of this subsidiary ridge is
the rocky summit of Arnison Crag. The slight col where the Arnison Crag
ridge connects to the flank of Birks is Trough Head.
To the east
of Arnison Crag is the lower portion of Deepdale and the settlement of
Bridgend. This flank is rough and includes Aiken Crag and the face of
Arnison Crag itself, just below the summit.
To the west,
separating the fell from the main ridge of Birks, is Hag Beck. This
flows northward from Trough Head, passing through the woods of Glemara
Park before issuing into Grisedale Beck just above the main road.
Glemara Park was once a deer park and now contains much broadleaved
woodland and a retaining wall which is still largely intact.
ridge from Trough Head to Arnison Crag is fairly level and passes over a
series of knolls. One of these, about hafway along, is the true summit
at 1,446 ft (441 m).
North of the summit, the ground drops
steeply over two tiers of rock outcrop, the lower one being Oxford Crag.
Arnison Crag meets the valley floor directly behind Patterdale village.
The summit is a low rock tower, attractively seen from the
surrounding valleys but there is only a very small cairn due to the lack
of available stone.
The view is largely restricted by higher
fells, but with the Fairfield and High Street fells well seen.
Ascents can be made from Patterdale village, either direct up the nose
of the ridge, or by curving round to the west and following the Glemara
Trough Head can also be reached from either Deepdale
or Hag Beck, providing an approach from 'behind' the summit.
Arnison Crag is often climbed as the first part of the ascent of St
Sunday Crag. From here the walker can either circuit Deepdale via
Fairfield, Hart Crag and Hartsop above How or swing north around
Grisedale, taking in Dollywaggon Pike, Nethermost Pike and Helvellyn.
