I've been checking out a line recently going up the centre of what I think must be this wall. Any ideas of what's been climbed on it? Where does the traverse go?

The traverse goes right into a widening crack feature near the arete. I think there's something E4ish up the middle of the wall but I'm not sure where it starts and there's at least one harder line heading up and left through the overlaps toward the top. Sorry to be vague, Doug Hall is the man who'll know.

I thought he was probably the best person to speak to! I'll try and get in touch with him and see what he knows, thanks.
