The height differentials are beyond belief.
"A diagrammatic 400 km north-south cross-section through the southern portion of the country at approximately 21° 30’ E (i.e. near Calitzdorp in the Little Karoo), showing the relationship between the Cape Fold Mountains (and their geological structure) and the geology of the Little and Great Karoo, as well as the position of the Great Escarpment. The colour code for the Karoo rocks is the same as those used in the above diagram. The heavy black line flanked by opposing arrows is the fault that runs for nearly 300 km along the southern edge of the Swartberg Mountains. The Swartberg range owes some of its great height to upliftment along this fault line. The subsurface structures are not to scale.
