The largest hill range is that which stretches from Bredasdorp 

 north-eastwards to Cape Infanta. Honing Rug, south-west of 

 Bredasdorp is really a continuation of this range. 



Near Bredasdorp the range is about eight miles from the coast, 

 but it gradually approaches the latter towards the east, until it finally 

 forms cliffs above the shore between Cupido's Kraal and Cape 

 Infanta. The range is over five miles wide in parts, and probably 

 exceeds 500 ft. in height ; it forms a barrier between the " Duine," as 

 the low-lying country between it and the sea is called, and the 

 " Ruggens." Both on the north and the south side it rises by steep 

 slopes like escarpments, and is traversed by deep kloofs running 

 parallel with the general trend of the range. On the north, the

Ruggens are of the usual undulating type of country, but on the 

 south of the range the land is remarkably flat, resembling a shore- 

 terrace. The level country is now covered by thin limestones 

 and sand-dunes, through which the same rocks which form the 

 Ruggens, namely the Bokkeveld and Witteberg beds, occasionally 

 appear. Along the present coast-line the sand-dunes, in places 

 transformed into limestone, are very similar in mode of occurrence 

 to the inland limestone range of Bredasdorp, and it is possible that 

 the latter was similarly formed along an ancient coast-line, and that 

 the sea has since receded. At any rate it is beyond question that 

 the inland limestone ranges are of a much more ancient date than 

 those along the present coast.
