Avalanche: NW Couloir

My partners and I were on the summit around 1:30. Temperatures were cool the sun was bright and there was no wind at all. We decided to ski the NW Couloir after evaluating stability on the way up. We could see The snow in the cirque had been slightly wind effected. We felt the most problematic area on descent would be the chutes at mid slope. After skiing the top 1000' we reconvened atop the chutes. The skiing was Sublime to this point and the snow was not sluffing and felt stable. The quality and stability to this point lowered my guard. My bright idea was to straight line the chute to stay away from the thin spots and stay light. As soon as I started a turn the slope spider webbed and the slab picked up speed. I tried to ski off the slab but eventually I was knocked off my skis but was able to dig the edges into the bed surface and arrest. The slide ran quite a distance below me. A very humbling experience and one to learn from.
