Bhatnara. 



Beyond that up the little valley near Bhatnara in a cul de sac 

 with the steep ascent to Changla above, the Jurassics (south-eastern 

 band) splay out over the hill-side shewing great quantities of 

 Gieumal sandstone for a while, until the glen closes in still more* 

 and the south-east band of the Jurassics vanishes under a covering of 



Nummuhtics, as drawn Fig. 27, 

 and the section coincides with 

 the Changla section. 



Towards the south-west the 

 doubled Jura-Triassic bands con- 

 tinue in regular order from near 

 Nugree for about 6 miles. The 

 section through them as seen 

 south-east of the ridge above 

 Chinali from north-west to 

 south-east is as follows : —
