70m, 2 pitches.
An impressive, freestanding, square-cut fin of rock marks the right-hand end of Chatter Buttress. The fin is defined by a distinct gully on the left-hand side, Noe Gully and a deep chimney, Thunderbolt Chimney, on the right. Climb the gully via a narrowing to the base of the fin then continue up the left hand, easy gully.
