Stoney Middleton?!

Got it in one :) It's the keyhole cave inside windy ledge.
Next question is - the cave has a right branch, which were were in (in a keyhole shape) and comes out round the back of the arete of Aurora, and a left branch, which is a less consistent shape. The left branch splits, and we didn't go further than that, as the left option was wet and the right one looked a little small - do either of those come out anywhere?

Think the left branch goes to Toms cave if i have my topography correct.

The left branch split, so would that be the left branch of the left branch or the right branch of the left branch? :)

You sure its not Gaylords Buttress?

Yes Mr King we all know how familiar you are exploring tight tunnels whilst wearing a brown hat...

You look like you are doing a poo.

According to 'The Caves of the Peak District' its real name is Bossen Hole, and the left hand branch becomes too tight, no mention of it splitting?

Ig does, but it also says the right branch emerges on the west side of the cliff, when I'm sure it should say East.

and why no helmet? caving is dangerous!

No helmet? We used to do the through trip without lights.

If you do it without a torch, its surprisingly easy to miss that right turn to Aurora.

strange looking creature this one.
