The accident took place on the Col des Montets.
It was his wife who was aware of the relief.
The PGHM gendarmes in Chamonix evacuated the victim in the early afternoon with a helicopter.
Careful in the mountains
Probably by the heat wave, falling rocks and landslides this summer were numerous on the Mont Blanc.
One of the most spectacular took place a few days ago on the edge of the cosmic.
In the middle of the summer it was Goûter's corridor that was not recommended by the landslides against the mountaineers. "The warning" was lifted mid-August.
