One finger hard wind slab failed on top of graupel layer toward the bottom of the new storm snow. Unintentionally triggered when my partner was stepping out a platform for a kick turn. Broke at our feet. There was a party of three below us but they were tucked away under the cliffs to the skier's left. 8" on the flanks and 24"+ in the center. We triggered it near the deepest part of the slab.
