On the occasion of the 150th anniversary of the first ascent of the Aiguille Verte, the Compagnie des Guides de Chamonix is producing a film retracing the major dates of this summit which is so dear to it. 'La Verte' has been the object of desire for many mountaineers for a century and a half. Big names have paraded in search of this 4122 meter summit: Edward Whymper, Michel Croz, Albert Mummery, Armand Charlet, Marco Siffredi... La Verte has had a strong impact on the history of mountaineering, inspiring Gaston Rébuffat who warned the future contenders for this summit: "Before the Verte you are a climber, in the Verte you become a mountaineer".
