Mont Granier (1,933m) is a limestone mountain located between the départements of Savoie and Isère in France. It lies in the Chartreuse Mountains range of the French Prealps between the towns of Chapareillan and Entremont-le-Vieux. Its east face overlooks the valley of Grésivaudan and Combe de Savoie, and the north face overlooks Chambéry. At 900 meters tall, Mont Granier has one of the highest cliffs in France.
Catastrophic 1248 Landslide
In the year 1248, between November 24–25, a mass of limestone resting on marls slid into the valley, causing a massive landslide that destroyed many villages and caused over a thousand casualties, although the numbers are still debated.[1][2] This event created the sheer 700 m north face of the mountain.
Five villages were partly or completely destroyed by the avalanche:
- Cognin
- Vourey
- Saint-André
- Granier
- Saint-Pérange (also called Saint-Péran)
Two villages were partially destroyed:
- Myans
- Les Murs (Les Marches)
The 1248 Landslide was one of the biggest and deadliest landslides in Europe.
January 9, 2016, Landslide
In the night of between January 8–9, 2016, a part of the northwest pillar crumbled towards Entremont-le-Vieux, where residents woke up at 5 in the morning. The collapse was of about 70,000 cubic meters of rock. The last debris were stopped by trees within 300 m of the closest houses, lying in the hamlets of Brancaz and Tencovaz.
