So I was scoping the beta photos for the Dutchman and noticed this line. It looks like it starts above Lamb's Slide, anyone know what this is called or have any beta on it?

that would be the upper right branch of lambs slide.
don't know of any other names... if you climb zumies thumb,
you rap into it.

Thanks Cor, I think it may also be called Zumie's Couloir. Seems to be pretty obscure, if anyone else has any beta I'd appreciate it.
