Aiguille de Bionnassay

ag de bion 1
The Auiguille de Bionnassay is a great ice and snow route, involving a mix of both rock and ice climbing. The approach was via the Conscrit hut where we spent a night. Then we continued on by climbing just below the Domes de Miage, to access the remote Durier hut @3400m. From here we began early the next day, climbing up the steep rock and ice face, to reach the summit of Bionnassay @4052m. The crest of Bionnassay is a wild, classic snow arete which is very narrow and super exposed. The steep and long North face of the peak drops 4000ft to the left, to the Glacier de Bionnassay. To the right drops to the remote Glacier de Bionnassay Italien. We continued to traverse along the knife edge ridge (in high winds!), before finally connecting us to the Dome du Gouter @4304m. We then descended down the standard Mont Blanc route.
