Thank you. A headwall block, like a large chockstone? I have trouble recalling much of what I wound up doing, but I do vividly remember being daunted by something very much like that.
My ascent was August 2014, so no snow--I made it up the initial crack, but I don't know if the supposed 'improvements' had been made at that time, or what they consist of. I've seen photos of the snowbank just to the west of the notch in spring/early summer conditions, and it does look easier.
I found ice on some of the final 400 rocks, even in August, but can't remember it posing much trouble, given due caution. I went down the main trail, so I didn't have to contend with it on a descent.
