Less powerful than the other routes on the Cobble Roof, but still bouldery. The classic 5.13a... in the Box, seems a bit stiff for the grade.
Start up somewhat insecure vertical climbing for a couple of bolts. Where the angle steepens move right then up into an undercling then jugs, finishing with a big move to the first horizontal. You can rest here or if you are a knee-baring master use the next hole to rest in. A couple of moves takes you up to that hole and a knee-bar off of a smooth cobble. Work out of the hole on jugs, then sidepulls and finally crimps, finishing with a big move to a softball sized cobble out left. Make the very powerful clip or blow it off. The next bit traverses right for about 8 feet to an almost flat 4 finger pocket and your next clip. Pretty much all the holds through this section are small crimps or terribly sloping, some foot trickery is helpful. Once in the pocket, head up and slightly right to a golfball sized cobble pinch and make a dynamic move to a positive 3 finger edge. More edges take you up the face past another bolt to the anchors.
