Grizzly couloir

First time on grizzly couloir! Skin track already set but partially filled in by wind drift in the alpine. Breeze approx 20km/hr from SW above 2500m during the ascent. Wind affected snow on Ridge leading up to summit - ski crampons were useful from approx 2300m. Boot pack from around 2500m on variably supportive snow . Wind slab on south east aspects noted at ridgline. Ski/board tracks noted from yesterdays party and slough run out at bottom, slab approx 15cm thick noted at edges of couloir. Belayed entry of first skier with a few big jump turns at the top. Snow felt supportive, minor sloughing in the upper portion and becoming firm down towards the choke. Soft powder on upper grizzly slide path. Creek not filled in completely down low.
