Mungrisdale Common lies north of Blencathra of which it is an outlier. Gently graded grassy slopes fall from Atkinson Pike, Blencathra's northern summit. Upon meeting the head of Blackhazel Beck, the shoulder divides in two, the northeastern arm connecting to Bannerdale Crags and the north western branch continuing to descend to Mungrisdale Common. Beyond an almost imperceptible depression the reascent is only 6 ft.
