 river-deposit, here consisting of sand, hardened by deposition of silica till it is a 

 compact mass of yellow quartzite ; the rounded surfaces of the weathered blocks are 

 wind- and sand-polished. In the distance the high-level plateau is well shown, 

 and there is an isolated flat-topped hill in the centre, similar to that from which 

 the photograph was taken.
