Graham and his companions next attempted a nearby peak, which they believed was the one marked on the map as A21, now known as Changabang. They made an ascent by the West Ridge, which Graham described as a fair climb, but [one that] presented no great difficulties. Modern observers, however, agree that whatever mountain Graham climbed it was not Changabang, which from the west presents a sheer wall which was not climbed until 1976, and certainly not the easy ridge that Graham described. It is more likely that he was on the wrong mountain; possibly a subsidiary summit on the southern ridge of Dunagiri.
