Overview
Mont Blanc, meaning "White Mountain" in French, is the highest mountain in the Alps and the highest in Western Europe, with a summit elevation of 4,809 meters. It lies on the border between France and Italy, and the surrounding massif also extends into Switzerland.
Geography and Physical Features
Mont Blanc is a heavily glaciated peak with several major glaciers descending from its summit, including the Mer de Glace, the largest in France. The massif is composed primarily of granite and gneiss and features numerous spires, ridges, and serracs that have made it a center of European mountaineering.
Significance
Mont Blanc is widely regarded as the birthplace of modern mountaineering. The first successful ascent in 1786 by Jacques Balmat and Michel Paccard is considered the beginning of the sport of alpinism. The Chamonix valley at its foot remains a global hub for climbing, skiing, and mountain culture.
Notable Facts
The Mont Blanc Tunnel, completed in 1965, runs beneath the mountain for 11.6 kilometers and connects France and Italy. The summit elevation can vary by several meters from year to year due to snow and ice accumulation. The Tour du Mont Blanc, a 170-kilometer trekking route, circumnavigates the massif.
