Unclimbed peaks
A team of Sherpas made the first winter ascent of K2, the world’s second-highest mountain. Are there any mountains left to climb?
— Gangkhar Puensum, a 24,836ft peak in Bhutan, remains unclimbed. Bhutan banned attempts to reach its summit in 1994, for religious reasons.
— Muchu Chhish, a 24,591ft peak in Pakistan, defied attempts in 1999 and 2014.
— Karjiang I, a 23,691ft peak in Tibet, was the subject of an unsuccessful attempt in 2001.
— Mount Kailash, a 21,778ft peak in Tibet, was nearly climbed by a British expedition in 1928. Reinhold Messner was invited to climb it in the 1980s but declined. A permit for a Spanish team was refused in 2001.
