There's a ledge under the curtain & overhang (near the bottom) with a belay bolt. You'll survive an avalanche if you belay the leader from there. Otherwise, you're a sitting duck. (I always cringe when I see folks belaying at the very bottom, like it's a sport climb at a gym or crag.)
Followed Brian (dunsum) up this climb after doing White Nightmare. Very similar to the climb to the right--they're both worth doing. Can get pretty picked out due to the traffic, but it's still a lot of fun. I think this means its typically in WI4 condition, but it CAN be harder.
