Located to the right of Bonzo Dog Band, look for the chimney start to the little roof. Or climb the arÍte to the roof. To pull the roof locate the vertical finger crack and finish it by connecting it with the top of Axe of Dog. If you start via the Axe of Dog and finish via the cracks at the roof, this is a very stout, wild, and excellent climb!
The main route for me here is Axe of Dog, but Ass of Dog shares the same start. Move left at the horizontal and follow a short crack up and then back right. Worth doing, much easier than Axe. With Stacy and Danny.
