Here's a couple more photos that fit the "crux in the dark" category.
They are from John and I's line on Nantina Point last season.
As to how much daylight this time of year, the more pertinent question is how many sets of extra headlamp batteries do you bring.
These are low on the pitch, and unfortunately don't show the WI6/M6 crux section up a little higher.
