Walked upon this along the beginning of the NW blunt ridge of Will's Hill. Could be either a remote skier trigger from a some tracks on the ridge before us or a small cornice drop. I suspect more on the side of remote trigger. Heavily windloaded. South facing of the ridge had HS 30-40cm while north facing was close to HS 3m. Was able to get very large and deep shooting cracks while walking on the ridge.
