This is the direct variation to the 2nd pitch of the Northwest Books and the continuation of the 5.9 corner system on the first pitch. From the top of the 1st pitch of the Northwest Books (assuming you've built your belay above the 5.9 corner), head straight up the left facing corner instead of breaking off right up the "wide" crack. Continue past a ledge and climb the next short and steep corner which deposits you on the left side of the big ledge that is the top of the normal route. Unrope from here and head for the descent.

This pitch was originally covered in moss and dirt, but thanks to some hours of brushing it's now in pretty good shape. There are a couple bushes still in the crack (hence the route name), but they are easy to climb around.
