326 PAIGE AND KNOPF STRATIGRAPHIC SUCCESSION IN ALASKA 



development of Jurassic and Tertiar}' sediments and the presence of 

 workable commercial coal in such a remote district seem of sufficient im- 

 portance to warrant the presentation of the following facts : 



Scope of the Paper 



An attempt will be made to give a brief statement of the stratigraphic 

 succession in the area traversed. It should be stated that diverse parts of 

 the field were covered by the writers respectively, and that the observa- 

 tions thus made were therefore in part supplemental. While the fauna of 

 Mesozoic age was almost in its entirety collected in the region east of 

 Chickaloon creek, the flora of the Kenai (Upper Eocene) was found on 

 the lower Matanuska river and on Chickaloon creek. 



Distribution of the Terranes

 and MesQ^pip ggdiments trends riorthwest across Matanuska valley aboiit
