Lepsius tunnel

The Lepsius tunnel near Innsbruck - Hötting was excavated around 1910 on the instructions of the Berlin geographer Karl Georg Richard Lepsius and under the supervision of Otto Ampferer . He was able to prove that there must have been at least two ice ages and not just one. The Höttinger Breccia is at this point underlain by a moraine and overlaid by another, so there must have been a long-lasting non-glacial deposit between the two glacier-related sediments.

Locality

The Lepsius tunnel is located along the Geologensteig above the Innsbruck Alpenzoo at approx. 750 m above sea level in the eastern Weiherburggraben ( Tuffbach ) . The breccia gives the old field name Auf den Grauem Stein for today's Hungerburg .
