Kindergarten Couloir

Attempted to ski kindergarten couloir. Low to moderate avalanche risk, with large cornices overhead. Started a bit late and only made it to the apron at 10am when it started to get noticeably warm. The apron was full of avy debris and large rollers (potentially from failed cornices?). Avoided the overhead hazard on the ascent into the coulior, however we noticed sluffing and either rock fall or cornice fracture during the ascent into the choke of the couloir. There was an overhanging cornice feature at the top of the couloir climbers left. Decided it wasn't worth the risk to try and ski the couloir. We skied the avalanche path on the other side of the lake which was heavy and crusty near the bottom and wind affected light powder at the top.
