In reply to Offwidth:
As an aside, and probably a dumb question but what does "climber's left" mean (in this case).
"Skier's left" is on the left when facing downwards. Normally "climber's left" I would regard as on the left when facing inwards and upwards. But what, as in this case, if the climber is descending and therefore maybe facing outwards and downwards?
