50 WYNNE : TRANS-INDUS EXTENSION OE THE PUNJAB SALT RANGE. 



From this place to Mulla Keyl the same general features are seen. 

 General features con- A strong cliff-line of nummulitic limestone occu- 

 tinued to west. pying the crest is more than usually tilted, dip- 



ping northwards at the peak called (on the map) Shekh Nikka Zyarut, 

 and from beneath this the thick light-coloured sandstone first appears, 

 then the Jurassic groups, and below these, near the foot of the hill, are 

 occasional exposures of the Ceratite shales or limestones and the underlying 

 carboniferous group. 



All along the southern foot of the range lies the broad zone of boulder 

 ground ; while to the north, beyond a long narrow valley called the 

 Khwurra-darra, coinciding with the strike of the rocks, and at its head 

 continuous with part of the Baroch-darra, rises the Shingarh range, hav- 

 ing heights of 4,836 and 4,926 feet. Still further north on the other side 

 of the Lawagarh stream is a parallel, but much lower, spur from the 

 Lakargarh scarp. 



All these last-named mountains are formed of the same Siwalik beds as 

 border the Chichali range elsewhere, conglomerates prevailing mostly in the 

 highest part of the group, and massive sandstones forming the rest, except 

 a narrow band of older-looking red clays and gray sandstones just near 

 the base, low down in the scarp facing the Chichali range itself. The bare 

 sandy surfaces of the Shingarh peaks are visible from a great distance, 

 and it is evident there is barely sufficient variety of texture among its 

 beds to mark its stratification and give it the ridge-like form it pos- 

 sesses. 



The section across this range, in figure 4 (at p. 58), is reduced from 

 that given on Colonel Walker's map, and with the sub-divisions of the 

 older part of the series added. The dip of the tertiary sandstones 

 (Siwaliks) did not appear so high as those given in the original section, 

 otherwise as a general representation it seems to express the features.
