Aiguille de Bionnassay, Alpine peak in Saint-Gervais-les-Bains, France
The Aiguille de Bionnassay rises to 4,052 meters in the Mont Blanc massif, featuring a prominent snow and ice ridge between France and Italy.
On July 28, 1865, Edward Buxton, Florence Grove, and Reginald MacDonald, accompanied by guides Jean-Pierre Cachat and Michel Payot, completed the first ascent.
Mountain guides maintain alpinism traditions on the Aiguille de Bionnassay by passing their knowledge of climbing routes to subsequent generations of mountaineers.
The Durier Hut at Col de Miage serves as the main starting point for mountaineers attempting to climb the Aiguille de Bionnassay.
Three major glaciers originate from the Aiguille de Bionnassay: the Bionnassay Glacier, the Italian Bionnassay Glacier, and the Miage Glacier.
