Good skiing on Aemmer's couloir. Fast travel conditions to Lake Annette and to the base of the couloir, bootpacking was generally boot-top. Descent offered good ski quality, mostly soft conditions inside the couloir. Very quiet morning up there with very little wind.
Found a skiff of wind slab (only 3-5 cm thick, easy to break apart) as we neared the top of the couloir but less than we were expecting.
