I would imagine that the sheep was 'shopped in as it wouldn't last 5 seconds on that rock, but I found this on for the actual place in question.
wedged between the walls of a mountain crevice in norway is a rock called kjeragbolten. the rock is often stood on by tourists for a crafty photograph whilst attempting not to look down at the 3000ft+ drop. i?m assuming the sheep/goat in the picture below was a local.
on further inspection, that sheep could well be real as you can just about see that there is a lower level either side of the rock, making it a useable bridge.
