SAND AND GRAVEL 



The sand and gravel industry is represented in every section and 

 nearly every county of the State. The deposits of these materials 

 are so widespread that usually the ordinary demands of each com- 

 munity, so far as building purposes are concerned, can be met from 

 supplies close at hand. 



The sand and gravel beds of the State belong mainly to the 

 Pleistocene formations, accumulated as the result of the great ice 

 invasion which moved from north to south and reached as far 

 south as northern New Jersey and Pennsylvania. This ice sheet 

 swept the rocks bare of their former mantle of disintegrated material 

 and in its place left a covering of transported boulders, gravels, 

 sands and clays. These deposits, when laid down directly by the 

 ice as ground moraine, are so intermixed as to have little or no 

 industrial value. Such unmodified drift covers a considerable por- 

 tion of the area, especially of the hilly country; in the valleys and 

 lowlands the ground moraine has been removed by stream action or 

 concealed below beds of sorted gravels and sands that were laid 

 down in bodies of standing water whose existence in most cases was 

 incidental to the flooded waters of the Glacial period. In some of
