Glacier de Taconnaz

Glacier de Taconnaz is a massive ice formation on the northern slopes of Mont Blanc, extending across several kilometers and framed by steep rock walls. Its distinctive crevasses and seracs shape the landscape and create an impressive display of alpine geology.

The ice has existed for thousands of years as part of the Mont Blanc massif's complex ice system. Through the 20th century, scientists closely tracked its movement and changes, making it an important window into climate history.

The glacier draws mountaineers and visitors who come to experience the raw power of ice and stone at high altitude. Its name carries Celtic roots that reflect the ancient connection between the land and the people who have lived in its shadow for generations.

Approach with caution, as seracs can break and trigger avalanches at any time. Visitors should only come with experienced guides and proper equipment, respecting any blocked areas due to hazards.

The glacier moves continuously downslope under gravity, creating constant cracking and fracturing at its surface. This active behavior makes it a living system that constantly changes and reshapes itself.
