From email: "My partners and I were booting up a couloir near abiathar and a large cornice fell and landed shortly below us in our bootpack. Spooked the hell out of us. We acknowledged the danger of those cornices before booting up, decided that it was probably safe due to relatively low winds and cool temps, and decided to go for it. In hindsight, we wonder if it was much warmer on the ridge near the cornice (we were in the shade), maybe we underestimated the ridgetop winds, or maybe we just got unlucky.
The cornice broke up a bit on some rocks before landing in our couloir, but there still vehicle sized chunks raining down. If we had been 5 minutes slower on the ascent we may have been killed."
