A. C. Peale — Application of the Term Laramie. 47 



He also believed that the u area for the solution of the 

 question [the relations of the well-defined Cretaceous group 

 with the Lignitic] lies in the Laramie plains and westward 

 towards Salt Lake."* It was intended that the name should 

 cover all localities in which the beds occurred. If any locali- 

 ties should be considered as typical localities they would be 

 those mapped by us along the Front Range in eastern Colo- 

 rado, and by King along the Range in Wyoming. That 

 Clarence King had no type localities of the Laramie plains in 

 his mind is also evident from the fact that immediately fol- 

 lowing his definition of the Laramie he gives as localities of its 

 occurrence the following in eastern Colorado, just north of the 

 area in which the Hayden Survey was at work : 



Parks Station, Colorado, 



6 or 7 miles west of Carr's Station, Colorado, 



West of Greeley, Colorado, 



Crow Creek, Colorado, and 



Platteville, Colorado. 



These are followed by references to "good exposures of 

 Laramie " east of Separation, and at other localities along the 

 line of the Union Pacific and in northwestern Colorado, f 



King refers to the exposures in Colorado as follows : " The 

 upheaved sedimentary rocks along the eastern foothills of 

 Colorado Range offer several admirable sections from the base 

 of the Cretaceous far up into the series, and these exposures 

 have formed the subject of continued study by Dr. F. V. 

 Hayden and the late Prof. F. B. Meek. The section, as elabo- 

 rated by them, has been constantly re-observed by us with 

 such concurrence of result that we have cheerfully adopted 

 their nomenclature from the base of the series up to the sum- 

 mit as defined by them. "J 



King, after summarizing the Cretaceous series as defined by 

 Meek and Hayden up to and including the Fox Hill Group, 

 says : § 



" Here, with those who follow Hayden, the Cretaceous 

 series comes to an end. Conformably over this [Fox Hill 

 Group] lies the group which Hayden and I have agreed to 

 call the Laramie, which is his Lignitic Group, and is con- 

 sidered by him as a transition member, between Cretaceous

fit is interesting to note that Carbon, Wyoming, does not appear in the 

 list, and that Carr's Station is only about 24 miles east of the lower end of 

 the Laramie hills, while the other localities are within short distances to the 

 east and southeast of the mountains.
