Armancette Glacier

Armancette Glacier originates from the Dômes de Miage at around 3,700 meters altitude and forms a valley glacier within the Mont Blanc massif. The terrain displays typical glacier features such as crevasses, seracs, and moraines that shift with the seasons.

This glacier formed during the Ice Ages as part of the Mont Blanc ice system and served for centuries as a known passage for high-altitude mountaineers. Like many Alpine glaciers, it has notably retreated in recent decades due to climate change.

Local mountain guides lead expeditions through this area, sharing traditional Alpine mountaineering knowledge with visitors who come to experience high-altitude climbing.

Accessing this glacier requires advanced mountaineering skills, specialized equipment, and experience with crevasse rescue techniques. Weather conditions change rapidly at this altitude, so careful planning and current local information are essential before any climb.

The meltwater from this glacier feeds the Nant d'Armancette stream and Armancette Lake, often displaying a distinctive milky color from glacial sediment. This appearance reveals the active erosion processes the glacier performs as it slowly moves through the massif.
