The north face of Chamlang, nearly 2,000 meters high and culminating at 7,200 meters, is one of the last great unclimbed faces in the Himalayas. Benjamin Védrines, who had scouted the face during a previous ascent of Chamlang in 2019 with Nicolas Jean via the northeast couloir, decided to tackle it with Charles Dubouloz, a very strong mountaineer but a novice at high altitude. Snow slides, suspended bivouacs, pitches of mixed climbing and vertical ice… The gamble paid off for the Frenchmen, who opened a new route, "À l'ombre du mensonge" (1,600m, 5+, m5+, 90°), after four intense days on the north face—a magnificent first ascent of a coveted summit, as a duo, in alpine style.
