Ansel Adams paid tribute to Sella's greatness in a 1946 article for the Sierra Club Bulletin when he wrote, "with Sella's sensitive insight and response the magnificence of mountains is distilled into a high order of expression."

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. The gentler southern side rises only a few hundred metres above the glacier of the same name: Lysgletscher.The Zumsteinspitze (Punta Zumstein in Italian) (4,563 m) is a peak in the Pennine Alps on the border between Italy and Switzerland. It is a subpeak of Monte Rosa.
