the Karen valley, the fault appears to terminate in a sharp synclinal 

 of the Nari beds, which is again seen on the southern side of the great 

 limestone cleft known as the Sahar Dat, 1 where the Sahar stream 

 traverses the southern continuation of the Piro range, which a little 

 further south joins the main Khirthar range to the westward, the syn- 

 clinal which separated them dying out. Water appears in several 

 streams, e.g., Mogrio and Trappen, along the line of this fault, the 

 general direction of which, south of the Kenji Nai, is from 15° to 35° 

 west of south, to the northward nearly north and south. 



The southern portion of this fault is evidently along a synclinal,

higher ranges the tendency appears to he towards faulted anticlinals. 

 In many places north of Dharyaro the east face of the main range 

 consists of a cliff, from the crest of which the beds dip at a low angle 

 westwards on the top of the range ; whilst from the bottom of the cliff 

 there is a steeper dip to the eastward, and the presence of a fault is 

 shown by the occurrence of Nari beds on the eastern slope. 



Although faults are not numerous, they were perhaps more common-

 a broken anticlinal as that 

 represented above, and it is continued for some distance up the gorge 

 of the stream above Chushang. Another small fault, seen in a cliff

 through the Khirthar limestone. The name of the Sahar stream is omitted on the Revenue 

 Survey map.
