Chamlang is a mountain in the Nepalese Himalayas, near Makalu. It lies in the southern section of the Mahalangur subrange of the Himalayas. Chamlang has an elevation of 7319 m. In 2021 a new, direct line up the sheer north face was climbed by two French mountain guides, Charles Dubouloz and Benjamin Vedrines. Climbing just as a pair, the route, which they named 'In the Shadow of Lies', took them four days to complete and included ice up to 90°.
