7m. This is a former route from the 1956 Volume 2 Climbs on Gritstone (Sheffield Area) Guide - Page 164 - Route no. 17. The route follows the dirty, V-angled chimney on the left wall of Broken Buttress Climb. Caution was required when using the large flake and associated chockstones, however these fell to the ground in the late 1960's.
