The neglected reddish wall to the south of the walk-in track, between the Lower Crags and Woodwind Wall. As with Woodwind Wall, Red Tier has a longish straight section running at right angles to the Ramparts, and reaches a
point at its easterly extremity before continuing in more broken fashion southwest towards Rawnsley Bluff. The ‘point’ at Red Tier is indented by a pair of smaller walls forming a square corner. This is where most of the routes are, and the corner is called Duck Bill.
