I also bought 'Geological Journeys' to assist me when attempting to interprete the earth's structure and it has made my trips more informative.  Tok Tokkie - Enjoyed your interpretation and your photos.

Does anyone one have photos of faults in SA?

charlw, unfortunately many (most) faults are not easily seen. The fault line may be hidden by loose sediment (like windblown sand, as on the Cape Flats, hiding the Milnerton Fault), except for when there was very recent movement. Google the San Andreas Fault and you'll see stunning photos of actual displacement along that massive fault.
Also erosion may partly erase signs of the fault where there was vertical displacement on the surface.
Also, remember that faults may occur deep in the crust and do not necessarily translate to the surface.

Let's go into the mountains...there's likely to be peace and quiet
