Spent 4 days approaching the mountain to 18,000 feet to the Alpamayo Col camp and summited on day 5. Got caught in a white out and was battling a sickness. My water froze and was with a partner who didn't allow me to eat. Became extremely exhausted and started passing out as I was climbing. Topped out just as things were getting crazy. Climbing through the cornices was quite intimidating with all the exposure down below. Threw up a bit on the way down and climbed down in the dark. The views were outstanding. Certainly a hardy mans mountain.
