It is hardly necessary to draw attention to the fact that in travers- 

 ing the Bulkot mass we have passed through the heart of a section 

 equivalent to that from Kalabagh to Koonja Gulee ; and it will be 

 readily understood from the way the dip varies as the core of the 

 ridge is approached how risky would have been the construction of a 

 section out of the surface indications supplied by the gulee ridge 

 exposures. 



In a north-easterly direction the Trias and Jura-Cretaceous beds 

 Parallel sections in exposed in the above section continue along the 

 the same ridge. t> e( i f t h e Hurroh and eventually join up with 



the same beds observed descending from the western slopes of 

 Kamur. No good exposures there were visited by us. To the south- 

 west, however, the northern side of the Hurroh valley is rich in num- 

 bers of beautiful exposures, the Cretaceous band being particularly 

 finely represented. The Trias platform sometimes projects a long 

 way out from the hill-side as represented below fig. 23, and having a 



moderate dip at the surface, 

 the outcrops V up the 

 stream-beds and sometimes 

 as near Dukkun and Gou- 

 ruh display complex fold- 

 ing towards the heart of 

 the ridge. 



Beyond Suttoruh under 



the crags of Balkooh the 



lie has changed and the 



Fie No 23. Trias and Jura-Cretaceous 



are inverted at the surface so that they climb up the hill-spurs 



instead of the ravines. 



Particularly beautiful is the aspect of the Cretaceous band, with 

 its black fossils standing out in relief on the pale orange coloured lime-
