9m, 2 pitches. 1) 4m. Start to the far left, around the corner from
'Treebeard Routes' and left of the oak. Climb the steep, reassuring chimney and finish left through good pockets, passing the sapling on your left, to a brambly ledge belay (optional).
2) 4a, 5m. Quest out right onto the North Wall and gain the well-protected horizontal break beneath the roof. Traverse right, protecting your second as you see fit, and cross the line of Revision Stress Arete, before finishing via the original route.
An enjoyable (if slightly tenuous) line, of which the exposed second pitch is an obvious highlight.
