Original description, 27 August 1936:
"A route was made up the centre of the Western Buttress starting halfway between the foot of the Central Gully and the start of the West Central Route. 300ft of easy slabs were climbed, then a traverse made to 60 feet to the left on a grassy ledge followed by 200 feet of steep slabs and another exposed traverse of 100 feet to the left across a trap dyke to a grass ledge (belay). 250 feet of very steep and exposed slabs with good holds were then climbed and the point where the West Central Route meets the Trap Face Route arrived at. The climb was continued up the Trap Face Route to the summit.
This gave a climb of 1100 feet entirely on slabs and without any unduly difficult pitches.
Good weather, 100 feet line, rubbers. Time 4 1/2 hrs."
