In the Bletterbach canyon there are rocks which come from the important transitional period from the Palaeozoic to the earlier Mesozoic era. Especially the Permian sediments are famous throughout the world on account of their various reptile tracks.

The oldest stratum is the Bozen quartz porphyry, formed around 260 million years ago. The youngest stratum is the sarl-dolomite, which is about 240 million years old.
