Guess where?

Cool, its clearly small berg, although the rock looks like it might be basalt, so it should be in the Sub-Alpine zone, probably around 2300m, but really (unless its on some obscure branch off a path I've been on) it doesn't look like somewhere I have been before (despite my previous comment, but the southern berg is really easy to spot), so I'm going with Bushman's Nek area, and lets go with Bushman's Nek Pass as a guess...

My guess would be the waterfall near the top of the gully directly opposite Mzimkhulu Cave. i.e. The gully you would ascend to continue traversing the little berg in a Northerly direction. There is a path marked up that gully on the maps, but as is usually the case for the Southern Berg, no path in reality.

Probably several other similar gullies to this in the southern berg so this really is just a stab in the dark for me...

ok, that explains why it looks so familiar, its in the hidden valley (since that forms the border between garden castle and bushman's nek. I'm going with Rob's Cave.
