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. Topography Souther Fell is the eastern extremity of Blencathra, a continuation of the arm that runs down from the summit over Doddick Fell and Scales Fell. A smooth slope falls eastward from Scales Fell to the col of Mousthwaite Comb at . The ridge then turns northeast for two miles along the summit of Souther Fell. 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 its 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. Geology In common with much of the Northern Fells, the Kirk Stile Formation of the Skiddaw Group predominates. This is composed of laminated mudstone and siltstone with greywacke sandstone and is of Ordovician age. The "Spectral Army" of Souther Fell On the evening of Midsummer's Day 1745, a line of marching troops, cavalry and even carriages was seen travelling along the summit ridge of Souther Fell. The ground over which they appeared to move was known to be too steep
