We rode the East face the 24th and today, and conditions were very very good. Light powder in the trees with no obvious instability issues other than dry loose in isolated steep terrain. Today there were wind whales pointed east at the ridge line above the face and bowl that formed since the 24th. We stayed away from the skier's right side of the slope, away from the line we skiied the 24th.

On the 24th one of our group ski triggered a windslab avalnche on the far skier's right of the East face, D1.5 R2 running for about 400-500ft vertical. The slab broke about 5ft above the skier, but he was easily able to ski out if it. The wind slab was very soft, about 13 cm of fist hard slab running on fist hard snow. The slab broke on about a 40 degree slope, on a convex rollover. With hindsite, I didn't realize there was a wind slab since it was so soft, and we got over confident since our first run down the mellower part of the slope didn't have any windslab that we noticed. The main thing it was a windloaded slope, easily identifiable after the fact. Luckily it was a good learning experience instead of anything worse.
