The crucial letter box hold visible next to Duncans' backside on "Two Stump Wall" and you also get an idea of the pocketed nature of the Leven Schist and that the boulder is quite big. Bouldering mats recommended.
Stumped. From the wall center go up to a good edge, move up and back left to join the above route 6a (V3) ***
Pocket Rocket. Step off the pointed rock left of the undercut crack onto the steep slab and move directly up 6a+ (V3) **
Right edge crack. Use the obvious under cling and careful feet to the obvious niche avoiding the temptation to cheat SS 6a (V2)
Pocket Wall. Just above the Block is an obvious and attractive pocketed slab
SS variation. Start low on the left moving across to a down facing nose then up and onto the slab above 6b (V4) **
