GLACIAL GEOLOGY OF THE SCHENECTADY QUADRANGLE 13 



course, due to the filling up of its channel, beginning near Schenec- 

 tady, with deposits of Glacial age, it took possession of this portion 

 of the Ballston channel as far as Aqueduct and from there on cut a 

 new channel in the rocks. 



The location of the buried channel .of the preglacial Mohawk 

 from near Schenectady eastward has not been determined. >he 

 borings already referred to indicate that there is a depression in the 

 bedrock in the locality north of South Schenectady. Along a line 

 extending from the bank of the river, at a point about three-fifths 

 of a mile west of the Schenectady waterworks to a point near South 

 Schenectady no rock was struck. Unfortunately the borings were 

 made only to a depth of 195 feet above sea level, so that the vertical 

 extent of the depression was not determined.
