Skiing inbounds off a convex rock feature. Partner went down, noted the slabby feeling of the snow, and skied out cautiously. I followed doing the same, and an unknown third person came up behind us without the same caution and released the slab while I was on slope. I was carried about 10-20m, never above my waist. Tweaked an ankle but otherwise fine.
Clear crown maybe 30-50cm tall (hard to say. I didn't go back up to check)? Over 10 but under 50m wide. Definitely storm snow that detached. Unsure if this slid on a crust
