Shooting cracks, wind slab with some hallow feeling underneath. Dug 3 hand shears on chair peak basin. One on the lower apron that had 0 Concerns. At 4800 dug two more on the NE aspect and found a deep 2.5-3 foot slab on top of a graupel layer that did come out with ease. We rode an adjacent chute that the only had a small wind slab layer with a solid amount of sluff that my partner and I were able to release and manage well.
