SAND AND GRAVEL 



Surficial deposits of sand and gravel are v^idely distributed in the 

 State and supply most of the needs for such materials in local build- 

 ing, engineering and metallurgical operations. The molding sands 

 of the Hudson river region also have an extensive sale outside of 

 the State. 



The sand and gravel deposits are mainly of glacial origin, as the 

 whole territory within the limits of New York, in common with the 

 northern section of the United States east of the Rocky mountains, 

 was invaded by the Pleistocene ice sheet which removed all the 

 loose material accumulated by previous weathering and erosion and 

 left on its retreat a mantle of transported boulders, gravels, sands 

 and clays. In places these have the character of unmodified drift, 

 or morainal accumulations in which the materials are more or less 

 intermixed, and are then of little industrial value. But more gen- 

 erally the deposits show a sorted stratiform arrangement due to 

 their having been worked over by the glacial streams and lakes. 

 Such is the condition in many of the larger valleys like those of the
