Watch François Cazzanelli & Giuseppe Vidoni establish 'Bianco Invisibile' on Aiguille Blanche de Peuterey

On 7 March 2025 François Cazzanelli and Giuseppe Vidoni made the first ascent of Bianco Invisibile on the east face of Aiguille Blanche de Peuterey (4112m) in the Mont Blanc massif. The pair set off at 4:30 a.m. from the Peuterey hamlet in Val Veny, skinned up for 1,600 meters, then established the 800m climb past difficulties up to 6c, M7, AI5.

Bianco Invisibile tackles a line between Vols Incertains (Sébastien Ibanez, Baptiste Obino 2022) on the left and the route put up by Arnaud Clavel and Matteo Pellin on the right and ends at the col at 3900m.

The climbers returned to their starting point at 11:30 p.m., exhausted but thrilled with their single-day ascent. "It was a beautiful, long day in the mountains — 18 hours of ski mountaineering, rock climbing, mixed climbing, and ice climbing. A bit of everything, just as we like it. And on a mountain that’s fallen a bit into oblivion."
