UKC

I was wondering if anyone could help with identifying the location of an old photo - hopefully this will be easy for people familiar with the area, but I've never been and there's little info provided with the picture. 
I'm assuming it was taken somewhere on the Yorkshire Moors, as it's from a collection of pictures my mum took when doing a dissertation on dry-stone walling in the area (coming up to fifty years ago now, but that's nowt to geology) . And it looks like it features a pretty distinctive rock that I imagine locals would recognise in a trice. Any ideas?

Allthough I cant be specific it looks very much like the sort of thing you find at Bridestones near Dalby forest

The only area in the NYM with stones like that is, as ebdon says is the Bridestones in grid sq, 87/91.

Is your mother's dissertation on-line anywhere?  50yrs ago I know, but I'm also a drystone waller - had to ask!

Possibly one of the Doubler Stones on Ilkley Moor West.

Spot on I think! https://www.realyorkshireblog.com/post/ilkley-to-the-doubler-stones-loop-wa...

Ignore my reply - I misread Yorkshire Moors for North Yorkshire Moors.

I agree too. The rock looks too dark for it to be at the NYM Bridestones

Same here, I clearly have North York Moors on the brain.  The above suggestion looks spot on.

Outstanding - I hoped the UKC hive mind would come up trumps, but that was even quicker than I was expecting. Thanks very much all!

To Billhook - I doubt the dissertation's online, I'm afraid, at least not in a form my mum would have been involved with. It was through Leeds Uni, I believe; possibly they have a digitised version, but it seems a long shot. I'll try to remember to ask next time I see her.

Thanks TeeBee.
