Snow on a mountainside can suddenly shift from calm to destructive force, as seen in the 1999 Galtür Avalanche. The process starts as invisible forces push against fragile layers buried beneath the surface. Tension rises as the snowpack shear strength threshold nears its breaking point. Suddenly, the weak bond ruptures and the snowpack collapses in a violent surge. This roaring mass hurtles down valleys at speeds reaching 250 km/h, reshaping the landscape. The enormous energy released by the avalanche transforms the mountain’s surface and leaves areas abandoned by humans. Follow for one real science fact every day.
