KAMET AND SPITI. 205 



up the steep triassic cliff (pi. n) is difficult, and even dangerous in 

 places, but the remainder of the way to the grazing grounds of 

 Dogkwa Aur is easy enough over rolling dip-slopes of upper rhaetic. 

 The actual section of the trias and rhaetic differs in no-wise from 

 those already described from Niti, of which they are only the north- 

 western continuations. I found here and there at the very base of 

 the cliffs which form the right side of the Hop Gcidh, upper carboni- 

 ferous white quartzite (8), overlaid by black Productus shales (9). 

 And the latter are invariably followed by the entire trias, grandly 

 developed, with the Otoceras beds (10) at their base. Fossils are 

 common, and had I had more time at my disposal I might have made 

 a very fine bag there, only I was daily sorely troubled by the Tibetan 

 guard, which had discovered me in the Hop Gadh, and whose object 

 was to prevent my onward march to Tsaprang, and eventually 

 Gartok. After days spent on various reconnaissances across the 

 undulating rhaetic hills around Dogkwa Aur, I had finally to give up 

 further explorations in that "direction, not on account of Tibetan 

 obstruction, but owing to the cow T ardice and scheming of my Indian 

 followers. 



The march back I accomplished by the Tsang Chok La* (see pi. 

 Return march to ll )) which affords a fine view over the grand 

 g " cliff of trias and rhaetic, not less than the 



palaeozoic sequence of the Tsang Chok La range or Jelukhaga. The 

 dip of the latter sequence seems normal and below the triassic cliff, 

 but there is good evidence higher up the Hop G3dh that a fault, 

 probably a fold fault, does run along this valley, for we have in places 

 upper carboniferous white quartzite (8), pushed over lower silurian 

 Cora I -limestone (4), and possibly higher up, east of Jessie's lakes^ 

 over the haimantas. 



The remainder of the march to Nilang brought me over the section 

 already noticed. I should have liked to examine the area north and 

 north-east of Nilang very much more in detail, but that was impos- 

 sible ; the ground is already claimed by Tibet as part of the province 

 of G'nari Khorsum, or Hundes, and Tibetan guards were black-mail-
