Glacial Burst at Tête Rousse
- When
- 11 July 1892
- Where
- Tête Rousse Glacier
An underground water pocket in the Tête Rousse Glacier burst on the night of 11 July 1892, initiating a flood in the valley above Saint-Gervais-les-Bains.
The event occurred on the slopes of Mont Blanc, specifically within the Tête Rousse Glacier. The sudden release of water dammed by the glacier caused an outburst flood that swept through the immediate valley, passing through the hamlet of Bionnay where some buildings survived.
