Very nice and bizarrely over-looked wall just right of the start of Equilibrium. Climb up the obvious arching undercut feature and gain the ledge, either with a super long reach for the tall, or by a spicy dyno. The landing is not too bad - 3 pads and a spot makes it safe as houses. There is a good hold in the back of the ledge - once you get this you can either scuttle off right into the chimney and escape, or mantle the ledge to an obvious jug and then scuttle off. The mantle is dirty and pretty 'engaging', so you're best off finishing on the ledge as the mantle adds little difficulty, but is plenty scary!
Hard to grade, so I'll say 7b, but its going to be a lot harder for the short. Its a really nice feature on some very good quality rock, and well worth doing. Just in time for the guidebook......oh......
