It is a newly cleaned crack up left by Swinging Affair.
look on MP.
I am pretty sure it was overlooked because the level of filth was a overwhelming cascade of crap. I think it is a cool climb.
The 2nd pitch has a cool few moves on it but the upper section dulls it down. I considered some bolted routes on the slab, or even a 2nd pitch for Swinging affair, there is a nice finger crack over there, but the slabs above are too easy.
