British Yangmolong 2007

Yangmolong (6,066m) is one of the few remaining unclirnbed 6,000m peaks in Sichuan, and only appears to have had one previous 'official' attempt. To acclimatise, this team made the first ascent of an unnamed peak of 5,596m (GPS reading) between Dangchezhengla (5,847m) and Peak 5850, and then a new route from the north on Dangchezhengla, joining the Japanese route at the summit ridge. Then, in deteriorating weather, they made an attempt on the north face of Yangmolong, but found that it was steep and difficult with serac barriers. They reached 5,400m before retreating.
