lol, that's cool with the climbers!
I have a similar sort of shot of the devils tower where there's 4 climbers. I think they might be a bit harder to see. They are sort of climbing up the middle in the shadow, there are 3 on the tower, and one standing beside a tree, I'd have to zoom the picture more to show the 4th person, but I'm afraid the shot was taken in JPEG and with a poor lens, so that's about as good as the shot gets.
please excuse the picture, was taken back in the day before I knew anything about cameras. (still don't really)
