Guess where?

Well, I can give you a list of passes it definitely isn't

I'm going to go with a wild guess and go with Mohlesi Pass. It looks southern Berg-ish, but I don't see giveaways on which pass it is.

Btw I have been able to upload on Mozilla, just only on a newer version.

Any chance this is 'Ice waterfall' near the top of Buttress pass?

The waterfall near the top of Icidi Pass?

Ntshintshini Pass? It would explain why you say I definitely haven't done it

Ntshintshini is at Vergelegen - apparently its hard to find. It tops out on the north side of a large waterfall near Mqatsheni Peak.

Ok - lets see, passes which top out to the right (true left) of a waterfall. There aren't many of these - there is Rockeries, Cockade (which I have stood at the top of and looks nothing like that), Ships Prow (definitely not), Ntshintshini and Amakehla. I'm not aware of any others. Literally every pass I have done tops out true right of a river or isn't on a river.

So my next guess, based on your clue Rockeries - but I don't think I'm right.
