Fromage's info is correct. My climbing partner, 3 buddies who skinned up to help with rescue, Patrol and SAR did a superb job. The rescue was well coordinated and efficient. We experienced a 20-30cm human triggered wind slab which built in the Bryant Chair Basin below and just South of the Chair Peak rap gulley during the course of our climb of the N face of Chair. My partner and I attempted self evac but failed secondary to my joint instability and shock. We were met at approx the thumb tack maybe 600 feet below the deposition zone. Tx at HMC for L radial fx, L fibula fx, L calcaneous dislocation, R 8th rib fx, R quad lacs, R facial lacs, bilatera peri orbital contusions. Deep gratitude for the assistance and support. Full report being sent to NWAC. More info as recovery allows.
