18m. Found in the northern zawn on the same wall as Boj Wolb. At the left hand end of this wall there is an obvious break running the full length of the wall. The Grin follows this in its entirety from bottom left to top right. A better (read cleaner) start can be made up the first 10 feet of Boj Wolb to the break then follow the break rightwards to where it thins leading to a tricky step and better holds.
