The Northwest Buttress team has summitted the north summit of Denali at 19,470′.  They left their high camp at 16,400′ yesterday and finished climbing the last section of the Northwest buttress to the north summit.  They were out of communication but contacted a Mountain Trip team camped at the 17,200′ camp on the West Buttress via FRS radio to report their success.  They were on the way down and reportedly a few hours from their camp when they made contact.  All sounded well, and they are surely sleeping late today and eating fat meals to celebrate.
