This expedition flew into basecamp yesterday evening, and are most likely moving to camp 1 at 7,200′.  Most expeditions do what is called single-carrying at the lower elevations on Denali; this is when a team will carry all their gear and food at once in a single massive effort to move camp and supplies.  Up higher teams switch tactics to double-carry, when supplies are carried ahead of camp to keep the loads reasonable.  Single carrying at altitude becomes too taxing, and carrying loads high and sleeping low aids climbers in acclimatization.
