Getting onto the DC was much more exposed and tenuous than I had expected - for me I'd say it was the highlight of the route.
We started out at 1am ahead of everyone else but were soon overtaken by guides as we made a wrong turn trying to get around the huge crevasse that had opened up at the bottom of the Cleaver. From there on we were jostling for position with them, arriving at the summit together at about 8am.
Aside from fighting with my two best friends all the way up, and getting caught in a bad storm under a lenticular cloud on the Muir snowfield, it was great. And I wouldn't have had it any other way.
