Stepped onto the edge of a cross-loaded start zone at the top of an obvious avalanche path on the south side of Trundle Point and released a wind slab extending from ski tips 30 meters into the path. Deepest point of the crown was approx 20cm. Ran full path 500m picking up what looked like some more wind deposits on the way. Did not appear to step down to any other layers from our safe vantage point. No skiers caught.
