In reply to k.shark:
not climbed but had a good look at it on the way up to organ pipe wall a couple of weeks ago. looked fair for a 4, yes its steep but you can get a good rest on the right half way up. I think the issue is that south gully of the black wall and quartzvein scoop are very soft for 4! of course ice forms differently every time so the exact line and steepness will vary, as is the case with any icefall. likewise there will be a difference between taking the line of least resistance and most resistance of at least a tech grade so it will be partly up to you how easy or hard you make it
