All is quiet from Everest this evening which means all of our teams have tucked in for the night. We received word that the Bouka family has successfully made it to Camp 2.

In addition, Camp 3 will soon be in rotation. The Ice Doctors and Sherpa have fixed the lines which means our team will now start carrying and caching oxygen to use on the upper reaches of the mountain.

Curious about the use of oxygen on Everest? Here is a little more background how we approach and allocate oxygen. In general, we run an oxygen flow of 3L/min or more while climbing, and 1L/min sleeping. This equates to about 8 bottles per climber, which means a lot of oxygen has to move up the mountain! We are proud to use hyper-efficient and state-of-the-art oxygen masks which help all of our climbers and Sherpa make the most of each oxygen bottle while on the mountain.
