Carboniferous and Permian are well represented north of the Cason di Lanza Pass with rich fossil records: plants, bivalves, brachiopods, but also large amphibians’ footprints.
This geotrail is laid out on the slopes of Monte Zoufplan and lets the observer examine the transition between the Dimon Formation
The route allows you to reach sites of great beauty, such as the Alpine lake of Bordaglia, and to take in the evident signs left by the Hercynian and Alpine Orogenies and by the erosive action of glaciers in the landscape.
This geo-excursion lets the observer examine the karst phenomena that characterize the limestone outcrops of the Alta Valle (upper valley) of the Bût torrent. The itinerary also leads to the karst source of the Fontanon and to one of the caves that form the complex subterranean system of the mountain overlooking the village of Timau.
Along this route you will be able to observe aspects linked to landslides, erosion and the accumulation of debris.
The Las Calas gorge is a natural monument carved out of the rock by water, which has polished it, creating evocative scenes. Along the way we can observe also the result of the enormous forces in action during the two orogenies and the crustal deformations that shaped the outcropping rocks.
