Did you know that even in Piedmont there are canyons? Well yes, in Antigorio Valley, in the province of Verbano-Cusio-Ossola, there are a series of gorges dug into the granite by streams that in the past flowed downstream of the Toce Glacier and called Orridi di Uriezzo.
The Orridi are characterized by a series of large sub-circular cavities separated by narrow and tortuous passages. The walls are all sculpted by niches and grooves produced by the whirling and violent motion of waterfalls. At certain points they get so close that from the bottom they do not allow the view of the sky.
South Gorge: called by the locals Tomba d’Uriezzo,[2] is the most spectacular, about 200 m long and 20 to 30 meters deep
North-Eastern Gorge: about 100 m long and about ten deep, very narrow at some points
Western Gorge: less characteristic, formed by two distinct sections.
A fourth gorge, which takes the name of Vallaccia, is located just below the Church of Baceno, but is difficult to access and ends with a jump on the river Devero.
