RECONNAISSANCE IN ARIZONA AND WESTERN NEW MEXICO ALONG THE 

 SANTA F£ RAILROAD 



BY N. H. DARTON 



[Abstract] 



The reconnaissance was made for the purpose of ascertaining the prospects 

 for deep wells to supply water to the railroad and settlements along its line. 

 The region examined was from ten to forty miles wide, and in this area the 

 principal structural and stratigraphic features of formations from Cambrian 

 to Cretaceous were determined. 



This was followed by the reading of 



GEOLOGIC STUDIES IN THE ALASKA PENINSULA 

 BY WALLACE W. ATWOOD 1 



[Abstract] 



Detailed work was done in the vicinity of Chignik, Balboa, and Herendeen 

 bays and on the island of Unga. The Balboa-Herendeen Bay district was 

 selected as a type area in the peninsula, and detailed studies were pursued in 

 the hope of working out a key to the general geologic conditions of this portion 

 of Alaska. 



The formations exposed include the Upper Jurassic, Lower and Upper Cre- 

 taceous, marine and fresh-water Eocene, Miocene, possibly some Pliocene and 

 Pleistocene, and recent Kenai plants were found associated with marine in- 

 vertebrate shells of Upper Eocene age. 



Vast quantities of igneous rocks have been intruded into the sedimentary 

 series, and overlying a portion of the area there are volcanic tuffs and basic 

 flows of post-Miocene age. 



Coal occurs in the Upper Cretaceous and Eocene. Gold and copper prospects 

 were examined at several localities.
