Blackfoot series 



Type locality of Blackfoot series : Canyon of North fork of Blackfoot 

 river, where the entire section is exposed. 



The red beds of the Camp Creek series rest conformably on the lime- 

 stones of the Blackfoot series, about a mile above the mouth of Camp 

 creek. The contact between the two formations can be traced for many 

 miles to the north, south, and southeast. At Camp creek the Blackfoot 

 limestones are broken by a fault in the canyon valley of Danaher creek, 

 but to the south, 10 miles west of south of Scapegoat mountain, the entire 

 section of the limestone is shown conformably beneath the Camp Creek 

 terrane in fine exposures in the canyon of the north fork of Blackfoot
