NO. I FORMATIONS OF BEAVERFOOT-BRISCO-STANFORD RANGE 49 



Canyon, also westward facing cliffs of the Brisco and Stanford 

 Ranges and the sections exposed near the head of and in Sinclair 

 Canyon, British Columbia, Canada. 



Derivation. — Name derived from Beaverfoot Range. 



Character. — Thick-bedded, cliff-forming, rather coarse, gray dolo- 

 mites, weathering to a light gray color and rough surface. 



Thickness. — Estimated to average 400 feet (121. 9 m.). 



Organic remains. — Lists on p. 13. 



Observations. — This formation is a fine horizon marker from the 

 north to the south ends of the Beaverfoot-Brisco-Stanford Range, a 

 distance of over 100 miles (160.9 km.). Burling in his section assigns 

 numbers 1-13 to the Beaverfoot, but it is quite evident that he has 

 included strata (9-13) that belongs elsewhere {ante, p. 6). 



Dr. Kirk's report on the Beaverfoot (Richmond) fauna is given 

 ante, p. 13. 



Sabine Formation 

 (a synonym of mons formation) 



Prof. S. J. Schofield suggests the name Sabine ^ " for the fos- 

 siliferous Upper Cambrian formation that conformably overlies the 

 Elko formation," on Sabine Mountain, which is in turn overlain by 

 the Devonian limestone. I found the fauna of the fossiliferous forma- 

 tion (Sabine) to be that of the lower Mons formation of the Ozar- 

 kian ^ and that of the limestones above to be Silurian and not Devonian, 

 also that the probabilities are that the " Elko " formation is not the 

 true Middle Cambrian Elko of Schofield but the representative of the 

 Upper Cambrian Lyell formation of the region north of the Bow 

 Valley-Kicking Horse Canyon area. 



The identification of the fossils, found by Schofield, as of Upper 

 Cambrian age is in agreement with their general character, but at the 

 time the strong resemblance of the lower Mons fauna to that of the 

 Upper Cambrian was unknown. The name Sabine appears to be a 

 synonym of Mons. 



WONAH OUARTZITE 



Type locality. — Southwest slope of Wonah Ridge of Sinclair Moun- 

 tain above Sinclair Canyon, at the northern end of the Stanford 

 Range, British Columbia, Canada. 



Derivation. — Name derived from Wonah Ridge. 



Character. — Thick-bedded, white to grayish-white quartzite.
