Of course this is the more traditional take on the formation. most images show the rocks bathed in full light just about an hour before sunset. I was on location in the winter when the sun set in the notch of the Cockscomb allowing for great light right p until about 10 minutes before sunset.
Walking out in the dark would have been a real challenge and even a little bit dangerous with out my hand held GPS. The terrain, slick rock and washes is an easy place to get completely lost. Once the sun set the temps dropped as well, plummeting to well below freezing. This flash froze any of the melt water on the slickrock making hiking a difficult and dangerous prospect in several locations.
