and the greater part of the lower slopes on the right side of the Sila- 

 kank stream. 



The snow-covered, ice-skirted peaks of the Chango (20,216') are 



also formed partly of the dark limestones of 



The Chango. 



this system (see sect. 1, pi. 3). At the latter 

 locality I touched the devonians in only one place, namely, at the 

 upper part of the Daldakharak No. 1 glacier, which has scooped 

 out its trough in the carboniferous system. The angular debris with 

 which the surface of the glacier is covered and which spread in 

 an enormous fan several thousand feet to the valley below are 

 entirely composed of fragments derived from the upper carboni- 

 ferous quartzite (8), the red Crinoid limestone (7) and the dark 

 blue G?>W-liiriestone (6). The higher slopes of the Chango are 

 practically inaccessible, excepting here and there, but fortunately 

 the colours of the several divisions are so distinctive, that I was able 

 easily to trace the approximate boundary of the beds along the east- 

 ern slopes of the Chango, as seen from the opposite heights. 



The range which extends in a south-easterly direction from the 



South-west of the Silakank stream to the Milam passes, and which 



Silakank. forms the north-eastern buttresses of the Duna- 



giri and the Nandadevi, all bear a cap of carboniferous rocks, resting 



on a base of older palaeozoics. 



The highest part of the range east of the Kharbasiya gorge, the 

 Marchauk and Hoti peaks, consists of the highly coloured upper 

 carboniferous beds, and a zone of the CVr^Z-limestone (6) crops up 

 below it, show r n both on the map and the sections 2 and 3, pi. 3. I 

 found that the CW^Z-limestone (6) with its base has suffered so much 

 by contortion, jointing, and faulting that it would have been impossible 

 to record graphically all the detached portions of the formation in the 

 rugged and snow-covered area of enormous peaks. The lines in the 

 map, of course, illustrate the distribution of rock-zones only diagram- 

 atically. 



Fossil traces are distributed throughout this formation, though 

 good specimens are rarely met with in the Niti area.
