Not sure I should mention it and spoil the fun but there is a snopes page explaining that the jumper wasn’t taking as much risk as you’re led to believe because there’s a ledge under him just out of the shot.
(Google for “snopes canyon leap”)
And get there EARLY or you will be at the back of the line for taking shots. Been lucky enough to be there twice. My rubbish shots from there are part of why I got interested in this hobby. The sights and colours are amazing. I think the scale of the place is what makes it hard to shoot too. Best memory …. being charged by a heard of mountain goats when they heard my camera click :-)
