Matterhorn mountain is situated in the Pennine Alps on the border between Switzerland and Italy. It is one of the most famous and distinctive of all Alpine peaks. The Matterhorn is a pyramidal-shaped colossus, standing at a skyline-dominating elevation of 4478 metres (14,690 feet tall) which makes it the sixth highest mountain in the Alps and in Europe. Its four steep faces rise above the nearby glaciers and face the four compass points, North, East, South and West. Although not the highest peak in the Alps its fame is due to its almost impossible shape; an unusual landform with a summit that appears to extend over its North face, making it look like a cobra about to strike.

The first successful ascent of this iconic peak was on July 14, 1865 by a team led by English illustrator, climber and explorer Edward Whymper. He had previously made several unsuccessful attempts on the summit. The climb was marred by tragedy as four team members lost their lives in a fall just below the summit during the descent. The second ascent occurred just three days after Whymper's triumph, from the Italian side. The mountain's difficult north face wasnÂ’t climbed until July 31 and August 1, 1931

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 kilometer (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 meters (3,600 ft) ice-covered wall, rising up from the Grenzgletscher. The gentler Southern side rises only a few hundred meters above the glacier of the same name: Lysgletscher.
