Travercing slope known the surface snow would sluff off on higher deg slope. skier pushed fracture of slide then choped with ski pole breaking remaing snow infront of him in 30 cm sections. Snow was expected We cut an 8ft wide 4ft thick 4ft deep cornice on the slope, no reactivity noted. (fun to do tho)
