Weissmies

Weissmies is a mountain summit in the Pennine Alps that rises to 4017 meters in elevation. Several glaciers cover its northeast, southeast, and west sides, shaping the terrain and the routes available to climbers.

The first recorded ascent of the mountain took place in 1855, when Jakob Christian Häusser and Peter Josef Zurbriggen climbed a route across the Triftgrat. This climb marked the beginning of mountaineering activity on the peak.

The name Weissmies comes from the local dialect and refers to white moss or snow cover that marks the summit throughout the year. This name reflects how people in the region have long understood and described the mountain's appearance.

To climb the mountain, climbers typically use the Hohsaas cableway, which reaches 3100 meters and serves as the starting point for the northwest route. From there, the summit is reachable over several hours of climbing, and mountaineering experience is needed.

The mountain's elevation decreased from 4023 to 4017 meters over recent decades due to glacial changes. This measurement shows how climate shifts affect alpine topography and influences its ranking among Switzerland's highest peaks.
