one obtains an extended view in the heart 

 of the Selkirk synclinorium. On the right 

 and in front are the structural features so far 

 noted. On the left, at the eastern end of 

 Cougar mountain the Nakimu limestone is 

 conspicuous in a steep rock-slope bare of 

 vegetation. Farther west, to the limit of 

 vision, the mountains are composed of the older 

 Beltian strata, dipping monoclinally to the 

 northeastward. 



Leaving Glacier, the train descends to the 

 "Loop", where the Selkirk tunnel will emerge 

 at its western end. On the left a brief view 

 is obtained of the Bonney glacier; on the right, 

 a closer view of the gray Nakimu limestone 

 on the western slope of the Cougar valley. 

 One kilometre beyond the Cougar watertank, 

 the limestone can be seen, continuing on the 

 regional strike over the col between Green 

 peak and Ross peak. The Caves of Nakimu 

 (Caves of Cheops) are irregular tunnels occupied 

 by Cougar creek in a subterannean part of 

 its course along the limestone. Here we have 

 the most westerly outcrop of this invaluable 

 guide to the stratigraphy of the Selkirks. 



For the next 5 kilometres the train runs over the 

 Cougar formation, here distinctly more massive, 

 homogeneous, and quartzitic than on the eastern 

 slope of the Selkirk range. To right and left, 

 heavy beds of white quartzite, interrupting 

 the dominant, gray and rusty strata, can be 

 seen. A narrow synclinal wrinkle affects the 

 95 m. general monocline about 1 kilometre west of Ross 

 153 km. Peak station and, in good light, can be 

 discerned in the high bluff on the left. 



Four kilometres beyond Ross Peak station 

 (94-2 mis.), the quartzitic Glacier division 

 of the Selkirk series conformably overlies the 

 dark-coloured metargillites of the Albert Canyon 

 division. The position of the contact between 

 98 m. these two contrasted formations can be seen 

 158 km. on the slope southeast of Flat Creek station.
