Monte Rosa is a mountain massif in the eastern part of the Pennine Alps. It is between Italy's (Piedmont and Aosta Valley) and Switzerland's (Valais). Monte Rosa is the second highest mountain in the Alps and western Europe, after Mont Blanc.

Lyskamm, also known as Silberbast, is a mountain (4,533 m (14,872 ft)) in the Pennine Alps lying on the border between Switzerland and Italy. 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 1 kilometre (0.62 mi) long ridge, both lying on the border between the Swiss canton of Valais (north) and the Italian region of the Aosta Valley (south). The northern side of the mountain is an impressive 1,100 metres (3,600 ft) ice-covered wall, rising up from the Grenzgletscher.
