these anticlines was deeply eroded by the pre-Uitenhage rivers, 

 which had east and west courses. The Uitenhage sediments filled 

 up the pre-Uitenhage valleys, and partially embedded the Zwarte- 

 bergen and Langebergen, and when they emerged from the water 

 they rose as a continuation of the main southern drainage slope ; 

 the result was that the Karroo rivers continued their courses across 

 the newly emerged sediments, and by the gradual removal of these 

 the rivers worked their way down to the underlying buried surface 

 of folded rocks. The Gouritz Eiver system is thus a superimposed 

 one as regards the country south of the Great Karroo, and by the 

 diversion of the Buffels, Meirings Pooi't, and Traka Eivers into the 

 Gamka, came to have its present form.
