Guess where?

I'm guessing its Injisuthi Pass, based on the clearly ascendable chimney.

Devil's Knuckles?

Edit: Actually - something about that photo doesn't fit the knuckles... too much of a grassy band? Anyway, I'm changing my guess to that gully route you did on the Rhino earlier this year.

So knuckles is close, lets see, passes in the very southern Berg that include rock faces and I do not recognise. Well considering I have had a failed attempt on 50% of Garden Castle's passes, all of which where south of Rhino, I know its not Mzimude (which I seem to recall Intrepid saying he's never done ), its definately not Bollard or Wilson, and its clearly not Mashai. Rhino Pass was already eliminated. That leaves Bushman's Nek Pass (which I beleive has no rock faces), Bushman's Pass, Thamathu Pass (which has no rock faces), Walkers's Pass (plausible), Iscitula Pass (I doubt it), Tsepeng Pass (cosidering what the area around that pass looks like, I doubt it), so unless its something really odd like Jonathan's Gate Pass, it could only otherwise be north of the Rhino...

So, based on the above, the only plausable option I can come up with is Walker's Pass, specifically the cave gully. However, your comment about it being warm is obscure, which one is warm...

In that case its easy, its that group of 3 peaks at the bottom of Rhino peak, don't know all 3 names, but the one is called the Little Rhino.

Yay, I finally get one of these right!

Ok, this one is either really easy or really hard, not sure...

Clue?

Think of the nickname of a character in the book/movie Spud...
