Monte Rosa itself lies near the intersection of a great north and south ridge, extending from the Balfrin through the Mischabelhörner, and the highest peaks of the mountain itself, to the Vincent Pyramide, and thence through the range that bounds the Val de Lys, nearly to Ivrea, with the transverse range lying between the Dent d'Herens and the Pizzo Bianco near Macugnaga.
