Synopsis top ↑

Austria and the Alps — these are two words which are inseparable, although from a geological viewpoint two entirely different worlds meet here — Europe and Africa. Searching through the millions of years of the Earth's geological history, one realizes that the various rocks forming the Alps reflect many different turbulent scenarios; tropical coral reefs, ice-filled valleys, deep oceans, shallow tidal-shelf areas, lava spilling volcanoes — all occurred together with violent earth-quakes and drifting continents. This, and much more is involved in the scenario that will be revealed as we travel through time over the wide range of the Austrian countrvside.
