Scafell Pike also has outliers on either side of the ridge. Lingmell, to the north west, is invariably regarded as a separate fell, while Pen, 760 m (2,500 ft), a shapely summit above the Esk, is normally taken as a satellite of the Pike. Middleboot Knotts is a further top lying on the Wasdale slopes of Broad Crag, which is listed as a Nuttall.
