My Wife and I decided that we'd follow the easiest approach as described by Handren as we were short on light, but shortly after the two large pines the cairns died and we were confused as to where we should be. Instead, we descended to what we thought was the 4th class approach pictured in the Handren guide (middle approach) and followed that.
The photos and GPS track contained here were captured on the descent in the hope it might avoid others getting lost.
The GPS track (N.B. - don't rely on this by itself, use your own judgement!) is available to download here:
