Europe's highest waterfalls dropping in three tiers over 380m. As it's a glacier fed waterfall, the highest flow is usually in the middle of Summer when the ice is melting, and it occasionally even freezes in the Winter during very low flow.
The different rock types that caused the waterfall to form originate around 100 million years ago, when the African tectonic plate began drifting North, towards the Eurasian plate. In the process, rock layers were lifted giving rise to the Alps over millions of years.
In the course of the plates colliding, underlying rock layers were pushed up in some places. Today these layers otherwise found far down in the Alps form the highest peaks of the Hohe Tauern (the region where the waterfall is found).
