In reply to gribble: Gribble, probably not a new route, so many people have claim new routes when 'lost' on Dream it will have been climbed before and will again. I would say there were claim annually in the Petes Eats new route book.
Sorry about that. Still look on the bright side you can still go back and climb dream again. Although I recommend the abseil to the ledge and then Concrete Chimney/Dream combo for the best outing on the slab.
