2025-08-20 - At least two people were killed and two others injured when rocks fell on the descent of the Égratz on the RN 205 near Chamonix in Haute-Savoie, France, Le Dauphiné libéré reported. The accident happened late in the day as motorists were descending from the valley toward Passy.

The report says a car carrying four members of the same family was struck by the falling rock. The two people in the front seats were injured, one seriously and one lightly, while the two rear passengers, identified as the couple's son and daughter-in-law, died. That casualty breakdown makes clear that this was a single-vehicle tragedy with a family at the centre of the impact.

French officials moved quickly to close the downhill direction of the road and establish diversions. The excerpt says the tunnel and alternate routes were affected, that rescue teams were on site and that experts judged the slope to be unstable. Those operational details explain why traffic disruption lasted beyond the immediate impact of the rockfall.

Le Dauphiné says 36 firefighters and 21 law-enforcement officers were deployed, and that an official on site described the event as dramatic. The source also reports that the damaged vehicle could not yet be reached, underscoring how dangerous the scene remained after the initial impact.

The road near Chamonix and Passy is a mountain corridor, which helps explain why slope stability is central to the incident. Still, the source does not provide a final geological cause, and the article should avoid saying more than the experts in the excerpt were prepared to say.

The verified story is therefore a mountain-road disaster with clear human consequences: a rockfall on the RN 205 killed two family members, injured two others, forced a closure and brought a large emergency response to an unstable slope.

The mountain-road setting is central because rockfall risk is not unusual on alpine routes, and the excerpt makes clear that authorities believed the slope was still unstable after the crash. That is why the road closure and diversion details are part of the story rather than side notes: they show the emergency was still unfolding.

The family composition inside the car also matters. The source says the victims were a single family group, with parents in front and a son and daughter-in-law in the rear. That gives the tragedy a clear human shape without needing any additional personalization or unsupported biography.

The article should avoid pretending the rockfall cause is known. The report says experts were still working and that the vehicle had not yet been reached when the scene was described. That means the most accurate tone is one of confirmation and restraint: two dead, two injured, and a road that remained too unstable for normal traffic.

The route closure through one of the main Chamonix approaches also meant the incident had an immediate tourism impact, even if the source does not quantify it. It is enough to say traffic was interrupted and motorists were diverted while the site remained dangerous.
