GLACIAL GEOLOGY OF THE SARATOGA QUADRANGLE 35 



that Miller 1 has reported evidences of an interglacial epoch in the 

 cutting of the gorge at Stony creek in the course of the Hudson, 

 and also in the case of the gorge at Conklingville in the course of the 

 Sacandaga river. 



THE EPOCH OF FLOODED WATERS 



There are conclusive evidences that after the ice had disappeared 

 from the area of the Saratoga quadrangle an epoch ensued charac- 

 terized by a flooded condition of the principal drainage streams of 

 the region. The old drainage axis extending from Corinth south- 

 ward across the quadrangle was again occupied by a river — a 

 stream of large volume and powerful currents. This stream swept 

 away a portion of the morainic dam south of Corinth and, following 

 the course of the present Kayaderosseras creek, eroded a broad 

 channel in the glacial till and, in places, cut through the till to bed- 

 rock. The stream discharged into Lake Albany at West Milton, 

 there depositing its sediments and building an extensive delta, now 

 represented by the Milton plain. 



At the same time flooded waters occupied the newly opened Hud- 

 son channel from Corinth eastward. They rapidly reduced, through 

 erosion, the impeding barriers in the bed and on the slopes of the 

 nascent valley, shaping it to its present features. 



We have now to consider the evidences of the occurrence of 

 these flooded streams of late glacial times : 



1 Portion of recessional moraine eroded and leveled by pow- 

 erful currents of water. The road which crosses Sturdevant creek, 

 2 miles south of Corinth, after ascending the slight hill to the east 

 of the creek, crosses a level area the surface of which is thickly 

 strewn with cobbles and boulders. Many of the stones have been 

 gathered, in clearing the ground for cultivation, and thrown together 

 in heaps, or used in making walls for fences. In some places, how- 

 ever, they have been left in their natural distribution and lie at the 

 surface of the ground in great numbers. In general they have the 

 smoothed and rounded forms of water-worn cobblestones. At its 

 eastern limit the leveled area is sharply marked off from the hills 

 of the morainic belt ; in part, by a somewhat steep and straight bluff 

 composed of the morainic materials. 



It is evident that this leveled area is a portion of the moraine 

 that has been reduced by the work of currents, the finer materials
