Can canyons also exist in Piedmont? Well yes, in the Antigorio Valley there is a series of canyons carved into the granite by torrents that in the past flowed downstream of the Toce Glacier and called Orridi di Uriezzo. About 12,000 years ago, this was the site of the Toce Glacier, in whose valley numerous streams and waterfalls flowed, eroding the rock over time to form this particular and fascinating natural spectacle that we now call 'Orridi di Uriezzo'. The narrow valleys, tortuous tunnels and gorges that can be admired today were formed once the glaciers disappeared. The drying up of the various streams fed by the glaciers left room for a veritable canyon that can be visited on foot today.
