In reply to NBR:
We were there yesterday. The most popular areas (Apple Arete, Elliott's, etc) are all clean. Slightly less popular but still starred areas (Moyer's Climb, Byne's Crack) were green and damp (wet in the case of Byne's) despite it having been dry for almost a week. I suspect a combination of dew and trees made it damp - by October the leaves should have fallen so it might dry out quicker.
Everywhere seemed to have a lot more heather than I remember from previous visits, even the cracked slab right of Apple Arete had lots (but now has slightly less!).
