New Kansas Tertiary Terrane—Adams. 303 
North Canadian and Beaver creek in what is now Oklahoma, 
is of the same age as the beds on the Cimarron in Kansas. The 
localities at which he observed outcrops are in the vicinity of 
Alpine and from them he obtained leaf impressions, fragmen- 
tary remains of fishes, small gasteropod shells, and diatoms. He 
also reported the proximal end of an ulno-radius bone of a 
camelid. This fossil he regarded as determining the age of the 
beds to be Loup Fork. The chalky beds he described as a 
“lacustrine marl.”’ 
The localities which were examined by Cragin were vis- 
ited by E. C. Case who reported his observations as “A Geo- 
logical Reconnaissance in Southwestern Kansas and No Man’s 
Land” (Kansas University Quarterly, Vol. II, page 143.) 
He found fragments of bones which could not be determined 
generically and obtained a collection of leaves which were 
referred to the genera Smilax, Sapindus, Ficus, Platinoides, 
and Populus. 
The purpose of this note is to record the occurrence in 
Kansas of the terrane first described by Cragin, and to call 
attention to this locality as a field which is promising to a 
careful collector. From what I have seen of the Tertiary of 
the great plains I am inclined to believe that the beds at Alpine | 
and on the Cimarron will prove to be older than Loup Fork. 
In this opinion I am supported by evidence afforded by its. dis- 
cordant relation to the mortar beds, and by the general re- 
semblance of the formation to the White River.
