314 THE OUDTSHOORN AREA 



the road to Waai Kloof from Worcester, and in a railway 

 cutting just outside Worcester Station. 



Between the Langebergen and Zwartebergen a very 

 considerable tract of country in the divisions of Oudt- 

 shoorn and Willowmore l is occupied by the sandstones 

 and conglomerates of this series. The longest area 

 extends from the west or right bank of the Gamka 

 River below Calitzdorp to near Tover Water Poort, a 

 distance of over seventy miles, but near Meiring's 

 Poort the width of the area is very small, under a mile ; 

 south of Coetzee's Poort the width is over twelve miles. 

 Along the northern edge of the area the conglomerates 

 He directly upon the Cango series ; but east of Meiring's 

 Poort they rest upon the Table Mountain sandstone 

 along the northern edge, and upon the Table Mountain 

 and Bokkeveld series on the south. The Olifant's and 

 Gamka Rivers flow for a considerable distance in rocks 

 belonging to this series. 



The conglomerates between Coetzee's and Potgieter's 

 Poorts closely resemble those at Enon. They are red 

 rocks, and weather into curiously rugged crags with 

 numerous small caves, and at places two caves on 

 opposite sides of a crag have met, with the result that 

 the crag has a hole through it. These conglomerates 

 were deposited against steep banks formed by the older 

 rocks. The conglomerates as a whole lie at the bottom 

 of the basin, or rather they crop out on its edge, and 

 are probably continuous under the sandstones and 

 shales that occupy a wide area within the basin. Very 

 probably the conglomerates were in part formed near
