The Bletterbach or more recently rio of the Leaves is a South Tyrol canyon that is located at the foot of the White Horn near the village of Aldino and is the largest gorge in the province. The term “Bletterbach” has its root in the retoromano plau which, in connection with the Indogermanic word plou means to flow, that is, flowing water. This canyon is very interesting from a geological point of view, as you look at the structures of the deep gorges and
at the same time the creation of the Dolomites
