shales determine the age of the beds. Mt. Good- 

 sir (11,676 ft.; 3,565 m.) is the highest in the 

 Rocky mountains near the railway. A glimpse 

 of this peak can be seen on the left of the rail- 

 way at about five miles (8 km.). 



Ottertail escarpment, showing Chancellor formation forming talus-covered, undulating 

 surface; Ottertail limestone in cliffs; and Goodsir shales on gradual slopes. 



8-2 m. Ottertail — Alt. 3,696ft. (1,127 m.). Forsome 



13- 1 km. distance on either side of the station the railway 

 cuts through highly sheared Chancellor shales 

 and slates which are here characterized by 

 their silken lustre and purplish gray color. 

 The river now flows almost due south at the 

 bases of Mt. Hurd and Mt. Vaux. 

 15 m. The railway turns sharply through an angle of 



24 km. 120 degrees to the northwest around the end 

 of a ridge of Upper Cambrian limestone. The 

 river continues to the south for about two miles 

 (3-2 km.) and then makes a similar sharp 

 bend to the northwest. At this bend is Wapta 

 falls, formed in the highly sheared, steeply 

 tilted Upper Cambrian slates. The Beaver- 

 foot valley extends to the left of the railway, 

 and was the course followed by Kicking Horse 

 river in pre-Glacial time. The stream course 

 was diverted largely by morainal obstructions.
