 The ridge is narrow to the east of the summit, rising over a series of knolls between the gradually diverging valleys.Westward it broadens considerably, swinging southward around the head of Codale Tarn before becoming indistinct in the general rising ground towards Sergeant Man and the High Raise massif.Codale Tarn is a shallow pool, its original outlet blocked by a moraine so that it now overflows via a rock lip.
