Nice one.
I'm surprised this doesn't get done more. That ski down from just below the summit of Torment was great. I'm sad we missed the couloir to Moraine Lake but that would have added another couple thousand vert and we were satisfied with what we had.
I believe we skinned up through the step. It looked steeper than it was. The crux is transitioning from the couloir to the glacier, which I don't think we even had rope to protect. I remember it feeling a little spicy.
EDIT: We actually did have rope, I just checked the photos. We didn't end up using it though.
