DESCRIPTIVE GEOLOGY: NUMMUL1TIC ZONE. 



211 



In the above section the complete absence of Spiti shales, and the 

 shadowy representation of the Gieumal sandstone, are peculiarities 

 which render the tracing of them, and of the boundary between the 

 Trias and Grey limestone, a difficult matter. 



TheSerh hill 

 has little of in- 

 terest attaching 

 to it. The junc- 

 tion in this case 

 between the 

 Trias and Num- 

 mulitics appears 

 to be a fault, but 

 that face of the 

 hill is so cover- 

 ed with brush- 

 wood and thorny 

 jungle that the 

 absence of the 

 Jura-Cretaceous 

 could not be 

 d etermined 

 every where. 

 Fig. 31 gives a 

 view of this hill 

 from the summit 

 of Janomar.
