NOTE: Not well described in recent guidebooks. They say that it lies in the Heaven Walls cutting but actually it is on the L (uphill) side of the fairly broad level you follow as you approach the cutting from the ruined building above the Yellow Wall incline rather than in the cutting itself. Also, it is on a barrel-shaped slab rather than a rib. Finally three bolts are mentioned but the 1990 (Nick Harms) guide noted that 2 had been stolen. At present only one bolt is visible from below.
The Mere Giggle (E1 5b) - Up and right from the 2nd bolt
The Sniggering Smear (E1 5c) - Left from the second bolt
The Biggest Joke (E1 6a) - Straight up!
