Dom, Mountain summit in Valais, Switzerland

The Dom is a 4,546-metre summit of the Mischabel group in the Pennine Alps, rising between Randa in the Mattertal and Saas-Fee in the Saastal. Its upper half is snow-covered, with dark gneiss ridges breaking through; a glacier, the Fee Glacier, lies below the east face. The normal route starts at Randa (1,407 m) and climbs 3,100 metres to the top.

The first ascent was made on 11 September 1858 by John Llewelyn Davies with guides Johannes Zumtaugwald, Johann Kronig and Hieronymous Brantschen via the Festigrat (north-west ridge). Davies published an account in Peaks, Passes and Glaciers. In 1875 the 1000-metre east face above Saas-Fee was climbed by Johann Petrus with Alfred and Walter Puckle and hunter Lorenz Noti. Arnold Lunn and Josef Knubel made the first ski ascent on 18 June 1917 by the Hohberg Glacier.

The name Dom refers to Canon Josef Anton Berchtold of Sitten cathedral, who carried out surveying work in the area in 1833; it is also recorded that he called the whole Mischabel massif "Dom". The neighbouring peaks were formerly known as Mischabel, an old German dialect word for pitchfork, after their close-set summits.

The standard route requires approximately 3,100 meters (10,000 feet) of elevation gain without mechanical assistance. Climbers should arrive well-prepared with Alpine experience and good physical fitness for the technical sections.

The Dom is the highest summit of the Mischabel massif, the tallest mountain group lying entirely in Switzerland. Its normal route from Randa gains 3,100 metres on foot, the greatest height gain of any Alpine 4,000-metre peak, with no mechanical lift on that side.
