Up ahead, Jian Jian rests his weight on his ice axe as we make the final push to the summit, which is visible on the left. It's a long, strenuous hike to the top of Haba, with no technical climbing. Check out the long line of climbers ahead of us. Many of them started out from base camp around 2:30 a.m. We started at 7:30 a.m. Our guide was wicked fast.
