1818 - la débâcle du Giétro
Directed by Christian Berrut2019 72mDocumentary, Drama,
1818, a particularly harsh winter. The Giétro glacier blocked the River Dranse until suddenly the ice gave way and a 32 metre high wave submerged the Val de Bagnes. Thanks to engineer Ignaz Venetz, an even worse catastrophe was avoided. The disaster led to the birth of glaciology and climatology.
