156 "WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB, 



The cliff-sections above the marl^ where not disturbed by sHpping^ 

 show the same series, the hard sandy dolomitrc 

 Cliffs. 13608 forming the cHff edge, overlaid by the " salt- 



pseudomorph zone/^ and this again by the con- 

 glomerates and sandstones of the "olive group/' the whole covered 

 over by the nummulitic plateau-limestone. Where this spreads over 

 the higher portions of the ground, under the action of the atmosphere 

 and rain, its fretted, gnarled and jagged surface forms narrow tortuous 

 channels, in which one can walk more than waist deep, and which are 

 most difficult to cross when covered by scrub jungle. 



At the head of the western Kusak glen, not far from the village of 



Batli, the cliffs exhibit the series as follows — the

The " olive group " seems here to be very thick in some localities, 

 and very thin in others. It consists of dark gray and olive sandstones, 

 olive-black shales and some beds of red shale, doubtfully referred to this 

 group on account of slipping, these probably forming the top of the 

 group below. Conglomerates of metamorphic pebbles occur as usual. 

 Some red sandstone and shaly bands also appear just beneath the 

 nummulitic limestone, but they are of subordinate character, and the 

 coal shales, if present, are generally concealed by the talus at the foot o£ 

 the limestone scarp. 



The old fort of Kusak, a stronghold of the Sikhs, is perched upon 



the lofty and precipitous southern end of a spur 



^"''^* from the plateau (see fig. 23, PI. XVII). The 



neighbourhood is much disturbed by slips or small faults, and the pre-
