§ 7. Beaverfoot Formation (" Halysites Beds "). 



McConnell ^ refers the " Halysites Beds " to the Silurian, recording 

 the presence of Holy sites catemdatus, Favosites, Zajjhrentis ?, and 

 some badly preserved gastropods, and this reference has been 

 accepted by subsequent writers. In 1913 Allan ^ records the close 

 resemblance of the " Halysites Beds " to the Intermediate limestones 

 (Devonian), near Banff, but he leaves them in the Silurian. 



At the meeting of the Geological Society of America in the winter 

 of 1915-16, the writer exhibited fossils from these " Halysites 

 Beds ", and presented a short communication ^ annoimcing their 

 correlation with the Richmond, a reference which was confirmed 

 by those who examined the fossils. This was the first recorded 

 identification of Richmond fossils in the Canadian Cordillera, and, 

 curiously enough, the fossils secured included one specimen of 

 Beatricea almost identical with one of the Beatriceas from the 

 nearest previously known Canadian Richmond — Stony Mountain, 

 near Winnipeg, Manitoba. 



The beds to which the term " Halysites Beds " have been applied 

 are in this paper called the Beaverfoot Formation from their typical 

 exposure in the crest of the Beaverfoot Range above Mons, which is 

 on the Kootenay Central Railroad, 15 miles south of Golden, British 

 Columbia. Reference to the section (§ 4) will show that the formation 

 is separable lithologically into two portions ; (1) the cherty limestone 

 series forming the exposed top (Beds 1-9 of the section), and (2) 

 the quartzitic series forming the base (Beds 10-13 of the section). 

 Only the upper portion, which becomes increasingly thin-bedded 

 and shaly as one goes down in the section, has so far proven 

 fossiliferous, and is referred to the Richmond. The lower portion, 

 arenaceous shales and quartzites, may prove separable from the 

 formation. 



§ 8. Glenogle {" Graptolite ") Shales. 



The first mention of the graptolite shales is by McConnell in 

 1887,* who says : " Easily accessible sections of the graptolite shales 

 close to the railway may be found in the bed of a small stream which 

 joins the Wapta from the north about half-way between Palliser
