Photo @Cory Richards // @adrianballinger on the windswept North Ridge of Mt. Everest. Today we begin our summit attempt without the use of supplemental oxygen in earnest. Hopefully, we will reach the summit on the 24th of May. Failure is a real possibility as climbing without Os dramatically decreases our chances of success and increases the possibility of dire consequence. Days like the ones ahead are when you are thankful to have a rock solid partner with you and a steadfast team behind you.
