While the update is a bit difficult to understand, we believe that this audio was called in by the June 17 Denali West Buttress team, who are camped at 7,800′. It is highly likely that the team spent today bringing a cache of gear and supplies to the top of Ski Hill at 10,500′, to bury for later on in their expedition. Caching and back-carrying (going back to retrieve buried caches from a higher camp) are cornerstones of long, expedition-style climbing, which enables teams to carry enough food and supplies for long periods of time spent on a route. Caching helps to mitigate the amount of weight the climbers will have to carry at any given time.
The weather should remain clear for at least two more days, hopefully allowing the team to progress up to Camp 2 at 11,200′.
If you can make more sense of the audio than we can, please let us know in the comments.
