 on its eastern flank. 



A few yards west of the crossing of Bath 

 creek there is a good exposure of Cambrian 

 basal conglomerate. It encloses fragments of 

 the underlying slate, but the exact contact 

 with the Pre-Cambrian is not visible along 

 the railway. 

 122-2 m. Kicking Horse Pass (The Great Divide) — ■ 

 195-5 km. Alt. 5329 ft. (1,625 m.). This is the con- 

 tinental divide. The pass, discovered by 

 Sir James Hector in 1876, is a saddle-like 

 depression about two miles broad carved out 

 by the ice. The grade from the pass to the 

 west into Kicking Horse valley is very much 

 steeper than it is to the east into the Bow valley. 

 To the right of the pass is Mt. Bosworth 

 in which there is exposed nearly 9000 feet 

 (2743 m.) of Lower, Middle, and Upper Cam- 

 brian strata. The Bosworth section was exam- 

 ined by Walcott (5) in 1908, this being the 

 first attempt to subdivide the Cambrian of 

 the Canadian Rocky mountains into form- 

 ations. From this point it will be seen that 

 the structure in the western slope of the Rocky 

 mountains represents the western limb of a 

 monocline; whereas the Cambrian basal con- 

 glomerate is exposed near the divide, the rocks 

 are Ordovician and Silurian in age in the last 

 range to the west. 

 125 m. Hector — Alt. 5,207 ft. (1,587 m.). The 



200 km. stream entering the lake at this point is Cataract 

 brook. It drains Lake O'Hara and Lake 

 McArthur, and glaciers on Mts. Victoria, 

 Huber, Hungabee, Odaray, Cathedral and 

 Stephen. Wapta lake at the right of the 

 railway is the main gathering basin for the 

 headwaters of Kicking Horse river. Below 

 the end of the lake the river has cut a canyon 

 through the Middle and part of the Lower 

 Cambrian formations. 

 128 m. From this point there is an excellent view 



204-8 km. of Yoho valley, a glacial U-shaped depression, 

 which heads in the Yoho glacier. The valley
