Despite a prominence of well over 300 metres, Lyskamm is sometimes considered to be part of the extended Monte Rosa group (in fact the Dufourspitze is only 107 metres higher). But visually Lyskamm is a huge massif, composed of two summits: the Eastern Lyskamm and the lower Western Lyskamm, separated by a long ridge, both lying on the border between the Swiss canton of Valais (north) and the Italian region of the Aosta Valley (south).
