[parks] presidential ADDRESS 41 



Schofield's report on the Cranbrook Map area which appeared 

 in 1915 is indicative of work somewhat farther west; and is an ex- 

 cellent example of a just combination of stratigraphie and economic 

 geology. The Palaeozoic strata are classified as follows: — 



schofield's table of the palaeozoic of cranbrook 



Mississippian Wardner formation 



Devonian Jefferson formation 



Middle or Upper Cambrian Elko formation 



Middle Cambrian Burton formation 



A comparison of these tables shows that there is room for further 

 correlation. The Permian age of the Upper Banff shale and the 

 Mississippian age of the Lower Banff limestone is questioned. Burling 

 differs from Walcott in certain views regarding the Cambrian sequence, 

 but while much remains to be done it is apparent that the stratigraphy 

 of the Palaeozoic of the mountains has received much attention and 

 wonderful advances have been made during the first two decades of 

 this century. 



The Palaeozoic stratigraphy of the western geosyncline can be 

 but briefly mentioned. We have seen that Dawson recognized the 

 Carboniferous age of the Cache Creek series and thus laid the foun- 

 dation for future development, with which is connected the names of 

 Charlee Camsell, N. L. Bowen, S. J. Schofield, and L. D. Burling. 



The Mesozoic and Tertiary formations have likewise been 

 examined in detail, particularly the former on account of the associa- 

 tion with coal. It is almost unnecessary to state that again we are 

 deeply indebted to the workers in the coal fields. Since 1900 the 

 Cretaceous has been subdivided and strata of Jurassic and Triassic 

 age recognized. In the Rockies and foothills of the southern section 

 we have now the following sequence of the Mesozoic: — 



mesozoic formations of the ROCKIES AND FOOTHILLS 



Cretaceous 



Upper Ribboned sandstone 



Kootenay coal measures 



Lower Ribboned sandstone 

 Jurassic 



Fernie shale
