  • Description 

    This route is located in a SW facing alcove just south of the summit tower. It is not quite visible in the Green Thumb photo on the Green Thumb rock page, however if you walk 50' south from where that photo was taken you would see this alcove.

    The vertical crack in the back of the alcove is Green Crack (5.8+). This route is the crack a few feet right of Green Crack that diagonals up and right. I would give this route 3 stars if it wasn't so short. The route is 50' long or less. Move left at the top and rap back down off a small tree.


    Mostly thin stuff, stoppers and small cams.

    I would rename this "Fingerless Crack", because, at least for me, it's too thin for fingers until the very top.....There is a nice face just right of Diagonal Finger Crack that can be toproped at about 5.8, maybe easier. The first moves are the hardest. It's strange that this is easier than the crack just to the left. This face may be "L.A.S.T." listed as 5.8 in Rossiter's guide and as location unknown.

    I have very small hands and fingers and was climbing it on "tips" technique for the bottom half, or sometimes locking my first pinky knuckle. No less, the feet are good and the climb is quite fun. Small gear is the order of the day and perhaps this route is not for beginning leaders, as such.

    Fun and aesthetic line... too bad it's not longer! A set of TCUs and RPs were perfect to sew it up, and there's an optional 0.75 cam placement for the final crack. Very worthwhile if you're in the area.

    Awesome climb! Too bad it's so short.... Would be a total classic if the business lasted more than just 25 feet. Even so, it is well worth the hike, and the gear (offset RPs, blue/black Aliens), while small, is bomber. Great way to get more mileage in after the third!
