KAMET AND SPITI. 203 



route to Tsaprang by the Tsang Chok La", as I traversed the strata 



mostly at right angles to their strike, and so obtained a better view of 



the stratigraphy of the area. 



Between the Jidh Ganga and the Hop Ga*dh I traversed nothing 



but fold after fold of much shattered haimantas; 

 Folds of haimantas. . , . , 



possibly some other members 01 the palaeozoic 

 group may have been inclosed in strips in some of the folds, but if so, 

 I could not separate them in the map from the haimantas, which is 

 the prevailing formation. They are mostly purple quartzites, green- 

 ish-grey phyllites and conglomerates. Being not only folded but 

 much shattered, their dip is most confusing, but there is a general 

 strike from south to north or south-east to north-west observable. 

 Between the second pass ("pass to Muling, etc.") and the upper 

 Hop Gddh I passed Jessie's Lakes (.fig. 6), calm sheets of wate r 

 caused by the damming up of the valley by glacial debris, and sur- 

 rounded by snow-capped rugged hills, formed of quartzites and 

 slates of the haimantas. 



After crossing a third and rather rough pass, I reached the upper 

 Palaeozoics of the Hop Ga*dh, and with it other members of the 

 upper H<5p Gadh. palaeozoic group. Both lower and upper Silu- 



rian I could recognize ; also the dark concretionary limestone of the 

 devonian is here represented, the whole dipping to north-east. 



'lhe Hop G£dh itself appears to correspond with a long line of 



fault, which may or may not be the continuation 

 Hop Gadh fault. J J 



of the great Niti fault; at all events it is in the 



line of strike of the latter, and the probability of these two fcaults 



being one is considerable. 



When moving down the valley of the Hop Gddh, I found that the 

 left side (see fig. 29) of the valley is almost entirely made up of 

 the older palaeozoics, whilst the right side presents the steep cliffs 

 of rhaetic, or rhaetics with trias below. 



A very good section through the latter I obtained in crossing the 



Section through trias ru gg e d cliffs on the right side of the valley to 



and rhaetic. Dogkwa Aur camping-ground. The first climb
