Natural cornice release between the upper small couloir and summit. SZ1.5 roughly ran 100-150m. The lower col between the "tit" and Charles Stewart S also ran natural SZ1.5 also suspected cornice trigger running an estimated 100m but in less steep terrain. (Sunday jan 9th) Monday jan 10th high W/SW winds still transporting plenty of snow into lee slopes. Wind slabs very prominent in alpine. Lee sides of alpine ridges seemed to have softer slabs more reactive than windward slabs.
