175m, 5 pitches. Central line of South Buttress off Heather Terrace. Sustained with good variety. 5 pitches - the fifth of which involves negotiating an overhang which is what probably takes it to HS and around 4b/c. Pitch 2 fairly exposed but easy climbing up chimney. Potential to link to Bubbly Wall or Arete Clim which avoids overhang.
