Pfad der Pioniere 02: Überraschungstäter

When earth and rock material mix with water during heavy rainfall and fall downhill, this is referred to as a debris flow or a debris flow. Due to the large mass and the usually high speeds, debris flows have a destructive effect. On 16 November 2002, a debris flow from Val Rascher carried 40,000 cubic metres of bedload and deposited it in the area of Post 2. That's about 6000 truckloads. The largest stone blocks weigh over 100 tons. The debris flow has knocked down around 1200 trees.
