 GEOLOGY OF SARATOGA SPRINGS AND VICINITY 



BY 



H. P. GUSHING AND R. RUEDEMANN 

 INTRODUCTION 



BY H. P. GUSHING 



The presence of a group of well-known springs whose waters 

 are of a somewhat unusual type, has long given prominence to 

 the region about Saratoga. A variety of causes has recently 

 increased this prominence and rendered it desirable that the 

 geology of the region should undergo more thorough investiga- 

 tion than it had ever received, in the hope that light might be 

 shed upon the question of the origin of the waters and the dura- 

 tion of the supply. 



It was the original plan to include in this report the geology 

 of the Broadalbin quadrangle, next west of Saratoga, which 

 was assigned to Dr W. J. Miller, but later developments led to 

 the abandonment of this plan and Doctor Miller's report has been 

 published separately.^ That work was done in close association 

 with our own, and in addition Doctor Miller also mapped some 

 30 square miles in the extreme northwest corner of the Saratoga 

 quadrangle. This service is emphatically acknowledged since the 

 country concerned is unsettled and difficult of access, and the aid 

 was rendered at a time when the writer was unable to engage in 

 field work as laborious as that which this district entailed. With 

 this exception. Doctor Ruedemann and myself are responsible 

 for the mapping. Much of the territory we have seen together.
