The Tauern Window is a geological sensation. The highest mountains in the Hohe Tauern region consist of rock strata that would otherwise be found in the lowest geological layers of the Alps. The Tauern Window lets you see these deep layers on the surface. It provides a view of the Earth's history stretching over millions of years. There are four massive gneiss cores at the centre of this geological window. These were created from liquid magma and formed the famous peaks such as the Grossvenediger and Hoher Sonnblick.
