20. Slightly calcareous, coarse, massive-bedded sandstones. 30 9.1 



Total Mount Whyte formation 762 232.2 



St. Piran Formation 

 Massive, purplish-colored quartzitic sandstones 20 to 30 feet 

 (6 to 9.1 m.), and then light gray quartzitic sands 

 with occasional bands of greenish, finely arenaceous 

 shale to debris at foot of cliffs. 



The above section is characteristic of the cliffs for 

 a long distance to the northwest of Bow Pass, and 

 also of the cliffs on the west side of the Upper Pipe- 

 stone River, and for twenty miles (32.2 km.) or more 

 on the west side of the Sififleur River north of Pipe- 

 stone Pass. The massive Eldon limestones cap some 

 of the higher points and ridges, but I did not attempt 

 to measure the section until the Saskatchewan Valley 

 was entered. The character of the cliffs and mountain 

 slopes is illustrated by plate 77. 



CLEARWATER CANYON AREA 



This section (D. on map, pi. 26) near the head of the Clearv^ater 

 Canyon is 33 miles (53.1 km.) east-southeast of Glacier Lake section ; 

 20 miles (32.1 km.) south-southeast of Siffleur section; 54 miles 



*A small fault of from 50 to 70 feet (15.2 to 21.3 m.) here cuts the section, 

 but the two parts are exposed in the cliffs facing north and above the talus 

 slopes of a small glacier.
