Flower Couloir, Bow Summit

Snowpack felt stable and good. Stickier on alpine sun aspects but good and soft on north aspects and treeline. One very localised whump on top of a roller / mound with some small exposed rocks - assumed rocks underneath and exposed area with recent snowfall and wind affect the cause, no other signs of instability.

Skier triggered size 1-2 avalanche in the Flower Couloir about 4 turns down the Couloir. Slope had recently slid already - within a few weeks as debris was visible along the slope already. Felt very stable bootpacking with a layer of fresh snow over existing consolidated layers & debris perhaps about 20-30cm. No sun exposure and a north aspect but steep slope. Skier slid the entire length of the Couloir and was able to self rescue at base of the slope. Burried lower body but able to stay on top as it was a shallow run out over existing debris.
