Unknown location, do you know?

excellent :¬) is it me or is that the rope around his neck?

If I was to guess I would say it's the top of Amen Corner on Gimmer, but I really can't remember what the top of it looked like. I've only been close to it on other routes, never at the corner itself. Hopefully someone can tell me if they agree or (more likely) that I'm wrong.

Hard to tell due to lack of background ...

Looking at the background, it doesnt look to be in the right position for gimmer

It's not amen corner, I recall that does not have a big nose at the top of it, just a big slab that goes off left

It could be the Wainstones on the North York Moors.

Hi,
Thanks, this was home ground for them so North York moors is a very positive suggestion

The slab below him looks like concave wall at the Wainstones, so that would make the route Wall and ledge route or Ridge route, great photo. G

It's the top few moves of Tiny's Dilemma at the Wainstones - he may have started up Morning Wall or Rookery Nook as these routes all share the finish.
