THE EARLY TERTIARY VOLCANOES OF THE 

 ABSAROKA RANGE* 



It is, I suppose, accepted by many geol- 

 ogists that volcanic energy has played an im- 

 portant part not only in bringing about the 

 present configuration of the Rocky Moun- 

 tains, but in building up the entire northern 

 Cordillera, stretching from the Front Kange, 

 along Colorado, Wyoming and Montana, 

 westward to the Pacific Ocean. Over this 

 wide area the volcanic phenomena of Ter- 

 tiary time present a varied and complex 

 mode of occurrence, offering from different 

 points of view many problems of geological 

 interest. These problems have been vigor- 

 ously attacked both in the field and in the 

 laboratory, and something has been accom- 

 plished tending toward their final elucida- 

 tion. The literature upon the subject is 

 already voluminous, being scattered widely 

 through the publications of oflflcial reports, 

 both State and National, and in the pro- 

 ceedings of scientific societies. While I de- 

 sire to call your attention to some of these 

 features, I do not propose to summarize the 

 work that has already been done in this 

 direction in a manner which is perhaps 

 usual on occasions like the present. Neither 

 do I wish to review the field from my own 

 standpoint, possibly because, although much 

 has been accomplished, such a vast amount 

 of work remains to be done that the broad
