Introduction 



The Cretaceous which underlies the Canadian plains is so nearly un- 

 disturbed that no great difficulty has been experienced in tracing over 

 large areas the diiferent horizons found. Near approach to the Rocky 

 mountains is, however, accompanied by serious foldings in the strata, so 

 that the foothill region requires detailed study before the formations can 

 be accurately mapped. The discovery of coal at several horizons renders 

 iihis folded area of interest on account of the many chances that the lower 

 horizons bearing the best grade of coal may there outcrop. 



The reported discoveries of petroleum in the southern portion of 

 Alberta were given great publicit}*" and the producing fields of Colorado 

 were cited as examples of what might be expected at almost any point 

 along the front of the Rocky mountains. The desirability of a study of 

 this region is thus quite evident, and last season one party was located 

 in the foothills south of the main line of the Canadian Pacific railway. 

 The work was intrusted to Mr D. D. Cairnes and considerable progress 

 was made in his examination. To correlate the several formations, fos- 

 sils were collected, but many are of plants which have not been studied yet.
