Matterhorn - Geography

Geography

The Matterhorn has a pyramidal shape with four faces facing the four compass points: the north and east faces overlook, respectively, the Zmutt valley and Gornergrat ridge in Switzerland, the south face (the only one south of the Swiss-Italian border) fronts the resort town of Breuil-Cervinia, and the west face looks towards the mountain of Dent d'Hérens which straddles the border. The north and south faces meet at the summit to form a short east-west ridge.

The Matterhorn's faces are steep, and only small patches of snow and ice cling to them; regular avalanches send the snow down to accumulate on the glaciers at the base of each face, the largest of which is the Zmutt Glacier to the west. The Hörnli ridge of the northeast (the central ridge in the view from Zermatt) is the usual climbing route.

Well-known faces are the east and north, visible from Zermatt. The east face is 1,000 metres high and, because it is "a long, monotonous slope of rotten rocks", presents a high risk of rockfall, making its ascent dangerous. The north face is 1,200 metres high and is one of the most dangerous north faces in the Alps, in particular for its risk of rockfall and storms. The south face is 1,350 metres high and offers many different routes. The west face, the highest at 1,400 metres, has the fewest ascent routes.

The four main ridges separating the four faces are the main climbing routes. The least difficult technical climb, the Hörnli ridge (Hörnligrat), lies between the east and north faces, facing the town of Zermatt. To its west lies the Zmutt ridge (Zmuttgrat), between the north and west faces; this is, according to Collomb, "the classic route up the mountain, its longest ridge, also the most disjointed." The Lion ridge (Cresta del Leone), lying between the south and west faces is the Italian normal route and goes across Pic Tyndall; Collomb comments, "A superb rock ridge, the shortest on the mountain, now draped with many fixed ropes, but a far superior climb compared with the Hörnli." Finally the south side is separated from the east side by the Furggen ridge (Furggengrat), according to Collomb "the hardest of the ridges the ridge still has an awesome reputation but is not too difficult in good conditions by the indirect finish".

The border between Italy and Switzerland is the main Alpine watershed, separating the drainage basin on the Rhone on the north (Mediterranean Sea) and the Po River on the south (Adriatic Sea). The Theodul Pass, located between the Matterhorn and Klein Matterhorn, at 3,300 metres, is the lowest passage between the Valtournenche and the Mattertal. The pass was used as a crossover and trade route for the Romans and the Romanised Celts between 100 BC and 400 AC.

While the Matterhorn is the culminating point of the Valtournenche on the south, it is only one of the many 4000 metres summits of the Mattertal valley on the north, among which the Weisshorn (4505 m), Dom (4545 m), Lyskamm (4527 m) and the second highest in the Alps: Monte Rosa (4634 m). The whole range of mountains forming a crown of summits around Zermatt. The deeply glaciated region between the Matterhorn and Monte Rosa is listed in the Federal Inventory of Landscapes and Natural Monuments.
