Souther Fell is a fell in the English Lake District. It stands to the south of Mungrisdale village in the Northern Fells. It is most famous for the appearance of a "spectral army", said to have been seen marching along its crest on Midsummer's Day, 1745. No such force was in the District at the time.
Mousthwaite Comb is a geographical oddity. To the north of the depression, running eastward, is the River Glenderamackin. To the south of the col, flowing westward is the same river. In the intervening time the Glenderamackin has run for six miles, surrounding Souther Fell on three sides like a moat. The Comb provides it's only dryshod connection to other ground and even this is almost cut off by the tributary of Comb beck on the southern slope.
The far northern end of the ridge falls quite steeply to a bend of the Glenderamackin, across which is the village of Mungrisdale. The eastern flanks are quite smooth and towards the south have been enclosed to provide pasture land. Southernfell, Far Southernfell and Hazelhurst are the farms here. At the southern end, on the turn of the ridge, is the rockier slope of Knotts, falling toward the main Keswick to Penrith road.
The western side of the fell stands above the enclosed valley of the Upper Glenderamackin, looking across to Bannerdale Crags. Souther Fell has two principal tops and each stands above a patch of scree and rock on this face. A footbridge crosses the river just north of Mousthwaite Comb, the only reliable crossing between here and Mungrisdale village.
26 sober and respected witnesses were assembled to view the proceedings and later testified on oath to what they had seen. The next day Souther Fell was climbed and not a footprint was found on the soft ground of the ridge.
The only scientific explanation ever offered was that this was some bizarre mirage or reflection of the army of Bonnie Prince Charlie, that day exercising on the Scottish coast.
This being the last of the Northern Fells in that direction, the view across to the Pennines is uninterrupted. The Lakeland view peeps around the looming presence of Blencathra, taking in Great Gable, the Scafells, the nearer Helvellyn range and a portion of the Far Eastern Fells.
