Descrizione

From the bivouac of Alpe La Colma, descend to Premosello along trail VBAA40, on a visible track, first through mountain pastures, then into a broadleaf forest, reaching the alpine pastures of La Motta (1139 m) and La Piana (999 m). Just beyond the centre of Alpe La Piana, you reach the starting point of the Colloro-Bacino-Alpe Lut-La Piana municipal road at an altitude of 960 m. Take it and then go downhill up to the junction for Alpe Lut, at an altitude of 800 m. At the junction, take the mule track that climbs to the right, reach Alpe Lut and, along trail VBAA38A, return to the municipal road and follow it to Colloro (500 m). In Colloro, continue along via Fontana del Bosco, to the far western side of the village. From here, along trail VBAA36, go down to Premosello and take trail VBAA00 that runs along via Cuzzi. Leaving Premosello along via Cuzzi, the route reaches the geological observation point dedicated to peridotites, which belongs to the geological trail of Vogogna-Premosello. After a short segment on SP 166 of Ossola Valley, the itinerary runs along the above-mentioned thematic route towards Vogogna (trail VBAA00D), climbing the rocky crags facing the valley floor of the river Toce, up to the ancient fortress of Rocca di Vogogna. The route goes further, along trail VBAA34A, to the hamlet of Genestredo (340 m) and from there, on a steep mule track, it reaches the Castle and the historic centre of Vogogna, where the leg ends.

Interest points

Between Vogogna and Premosello you can follow a geological itinerary equipped with didactic panels. The trail offers the exceptional opportunity to "cross" the continental crust, observing rocks that formed at different depths and in different periods. Along the equipped itinerary you pass from the European paleocontinent, involved in the genesis of the Alps (50 - 30 million years ago), to the African paleocontinent that preserves rocks and structures formed about 300 million years ago; at the same time you "descend" to the contact between the crust and the mantle, generally located at a depth of 30-35 km, here exhumed by tectonic processes. The route, equipped with explanatory didactic panels, climbs from the castle of Vogogna up to the Fortress and then it continues along the rocky crags overlooking the Toce plain up to Premosello. In the westernmost part, the route crosses the phyllite rocks deformed by friction along the Canavese Line, a strip along which the alpine construction overlapped the most ancient southern area of the Alps. A little further on, you can observe the direct contact between the rocks of these two areas (Schists of Fobello and Rimella and granulites of the deep crust of the Ivrea Verbano area). From a panoramic viewpoint, located on "sheepback" rocks, you can observe the pre- and post-glacial morphology of Toce Valley. After coming across the pseudotachylites, testimonies to ancient earthquakes, at the eastern end you can reach the contact between granulites and peridotites, which represents the discontinuity of Mohorovicic (or "Moho"), that is, the crust-mantle contact.
