Mont Blanc — rockfalls due to heat

On 21 August 2026, it was reported that the Mont Blanc massif had been destabilized by summer heat and rockfalls. The day before, on 20 August 2026, a rockfall above a Swiss ski resort had raised fears of another Blatten-style disaster. Alpine hikers and climbers should treat high routes and approaches to resorts as dangerous and check with local clubs or rescue services before setting out.
